Volumetric Vinegar Analysis

Experiment 9 and 10: Volumetric/Vinegar Analysis Abstract: The goal of the experiment that was conducted was to figure out both the molar concentration of NaOH and the standard mole ratio of the NaOH solution. In order to find the concentration of the NaOH solution, volumetric analysis was used. In volumetric analysis, a titration mechanism was utilized in order to find the reaction that the base will end up having with KHC8H4O4. , also known as KHP. Phenolphthalein, which is the indicator that was used in this experiment, assisted in figuring out at exactly what point was there neutralization.The indicator turns the solution into a bright pink color once neutralization has occurred. In experiment 10, the average molarity of NaOH that was found in experiment nine was used in order to find out if the vinegar that was being used in the experiment contained around the same percent mass of acetic acid that is found in regular vinegar. The experimental value of NaOH that was used was 1. 0 425 grams and the molarity of NaOH was found to be 0. 089 m/L of NaOH. Towards the conclusion of the experiment, the average percent mass of acetic acid was calculated and found to be 1. 695%.Regular house hold vinegar’s average percent mass of acetic acid usually ranges to 4-5%. Based on the percent mass of acetic acid obtained in the experiment, the vinegar that was used in experiment 10 was clearly not house hold vinegar. The hypothesis for this experiment was, if the average percent mass of acetic acid ranged between 4-5%, then it is house hold vinegar. However, due to the results from the experiments conducted, this hypothesis was rejected. In order to obtain the results that the groups were searching for, titration was used in both experiments to find the answer.The method of titration involves the measurement of KHP and NaOH. Afterwards, the volumetric analysis was used, with the indicator included. The experiment starts by finding the measurements of KHP. The indicato r was added later on, and then the titration began with the NaOH solution. It was apparent once the solution was neutralized because the indicator caused the solution to turn bright pink. The experiment also required the utilization of volumetric mass in order to find the percent mass of acetic acid in vinegar.The mass of vinegar is then titrated along with the indicator endpoint with the sodium hydroxide solution. In order to find the average acetic percent mass of vinegar, the concentration found in NaOH in experiment 9 was utilized together with the known volume of NaOH. Materials: Please refer to Experiment 9 and 10 on pages 127-136 and 137-142, of Laboratory Manual for Principles of General chemistry 9th Edition by J. A. Beran. The only deviation that was performed during this experiment was the two to three extra drops of the indicator phenolphthalein in order to distinguish a titration point.Results: Experiment 9: Data: |Table 1: Measurement |Trial 1 |Trial 2 | |Mass of KHC8H 4O4.

Avg. Percent Mass of Acid in Vinegar (%): 1. 65%+1. 74%/2= 1. 695% Discussion: The experiment began by adding NaOH to the mixture of deionized water and KHP in the beaker. The H+ ion that is found in KHP, reacted to the OH- ions that are found in the NaOH solution, even as more of the Na OH continued to be added into the mixture.When there turned out to be an abundance of NaOH, there were no longer any H+ to be added to KHP. As a solution, the extra OH-ions were found in the NaOH solution was used to make the indicator activate and make the solution turn pink. It was imperative that the solution be mixed the correct way. If it was not mixed the correct way, the results from the experiment will be inaccurate. If the reading had proven to be inaccurate because of that mistake, the volume of the NaOH solution mixed with the KHP will eventually get neutralized to a point where the numbers in the results would be very off.Two trials were done in this experiment in order to ensure that that mistake never happened and the volume of NaOH was found. Once the solution had finally been able to neutralize, the moles of the KHP were found and ended up being equal to the moles of NaOH. This information allowed for the molarity to be found. The average molarity that was in NaOH ha d been found in experiment 9, it was . 089 M. Both experiments 9 and 10 seemed to have similar traits because both of them involved titration. The titration was used in order to find the number of moles that was found in the acetic acid of the vinegar solution that was used.The normal amount of acetic acid found in household vinegar is between 4-5%. The experiments helped determine that household vinegar was definitely not the vinegar that was being used since the acetic amount that was found was 1. 695%. Conclusion The hypothesis was proven in the first experiment because the base of NaOH did end up neutralizing KHP’s acids. The indicator turned the solution pink; therefore the hypothesis in the first experiment was not rejected. The experiment involving the molarity of NaOH was very close in numbers. The molarity that was given was . 1 M, and the molarity that was found in the experiment was . 89 M. The hypothesis for the second experiment was â€Å"If the average percent mass of acetic acid ranged between 4-5%, then the vinegar that was being used for the experiment was household vinegar. † However, since the average percent mass of acetic acid resulted as 1. 695%, which was lower than household vinegar; this caused the hypothesis to be rejected.

Coffee Bean Essay

The Coffee Bean & Tea Leaf was founded by Mona and Herbert Hyman and it is established in Los Angeles, California in the year 1963. The first Coffee Bean & Tea Leaf were established here in Malaysia in 1997. The company offers a wide variety of its own signature beverages that ranges from coffee to non-coffee drinks and launched their very own signature drink; â€Å"The Original Ice Blended† in 1989 and has been the main highlight of its company ever since. We will take a look into the possibility of bringing in a new product that could be a mainstay for the Ice Blended range that is already available here in Malaysia. Currently, the range of its Ice Blended drinks is limited to several coffee and non-coffee drinks. Although from time to time Coffee Bean has been introducing promotional and seasonal Ice Blended drinks, none of these drinks will be served in the main menu after that the promotion is over. With this. Although a majority of Malaysians like to drink coffee oriented drinks, With the introduction of the Honeydew Ice Blended to the market, it will help boost the challenge of bringing in new flavors for the market. Situation Analysis The Coffee Bean & Tea Leaf is entering its fifteenth year of operation in Malaysia with many of its products ranging from its well known â€Å"The Original Ice Blended† beverages which carries coffee and non-coffee drinks have been well received by the public. However. 2.2 SWOT Analysis The following SWOT analysis captures the key strengths and weaknesses for the proposed product and describes the opportunities and threats that it will face. 2.2.1 Strength The Honeydew Ice Blended drink is offered during the summer seasons and it is well known as the refreshing summer drink in United States. With summer all year long in the South East Asia region, this product has also been proven as a main-stay in the Philippines and Singapore’s The Coffee Bean & Tea Leaf. This product carries a cool, chilling and refreshing sweet taste which suits the pallets of the South East Asian region. 2.2.2 Weaknesses This product may not be suitable for coffee drinkers as the drink does not offer any coffee taste and it’s a fruit oriented drink. It’s also not suitable for those who are watching their calories and diet as the drink carries a high calorie range due to the sweetness and the cream that the drink offers. As this product targets the youth which comprises of teens and working adults in their twenties, some may be price sensitive to this beverage offer as it may be expensive compared to the local. 2.2.3 Opportunities Younger generations, whom fell under the legal drinking age, are known as one of the fastest-growing segments of the beverages market. These generations prefer fresh and upcoming products rather than stagnant products that they have consumed daily. With a brand new product being introduced, it will trigger the targeted younger generation with the enthusiasm to go. The lifestyle factors converger. 2.2.4 Threats Global coffee and tea market have been increasingly growing and it has since been an extremely competitive sector. Coffee Bean & Tea Leaf goes up against its closest rivals such as Starbucks, Dome, Cha Time and Old Town Cafà © here in Malaysia. Competition The Coffee Bean & Tea Leaf has been a powerhouse brand in providing its ice blended beverages. However, there are companies that do make similar ice blended beverages such as Starbucks and Cha Time. The Coffee Bean & Tea Lead has the upper hand because of the creation of the â€Å"The Original Ice Blended† line which gives the company the extra edge. Although the mentioned competitors have been making ice blended beverages, The Coffee Bean & Tea Leaf has its own signature way of making these beverages special and cannot be matched with its competitors.

Sociology (Reaction paper 3) Essay Example | Topics and Well Written Essays - 750 words

Sociology (Reaction paper 3) - Essay Example The right to free speech, the right to gather with one another to discuss thoughts and ideas, are among the many rights that individuals seek to have for themselves. While many are fortunate and achieve those very rights, some are not as lucky. From the beginning until the era of the feminist movement, the rights of women would pale in comparison to the men around them. Most notably, their ability to vote and also their presence within the work force. Not only the question as to whether or not they would work but also the consideration given, to what placement they would have within the corporate structure. The role of the United States should be as a leader for the cause. The very nation that would not only ensure the rights of its own citizenry but also, seek to ensure the rights of the millions of other people that live throughout the world. To show the other world leaders that, by maintaining a practice of human rights protection, it can only serve to benefit the success of the nation as a whole, rather than it being a hindrance. Thomas Jefferson, one of the most notable founding members of the United States, would speak eloquently about the notion of all men being created equal. With the ability to vote being given to women and later on during the 60s being given to African Americans, the level of credence to the idea of protecting basic human rights, would be placed on the forefront. Seeking to classify both women and African Americans not by gender and/or race but rather, seeing them for the human being that they are. Going below the surface and realizing that, in all reality, every human being remains just that at their core.. a human being. Each and everyone deserving of the same rights as others, no more and no less. To define prejudice, that would be the act of placing judgment upon a person, place and/or thing, without having any personal experience on the matter. Such as, hearing a negative story from another

Attraction in Interpersonal Relationships Essay Example | Topics and Well Written Essays - 250 words

Attraction in Interpersonal Relationships - Essay Example I could say that it was her demure and reserved character, as well as her sharp mind and strong work ethic that attracted me most. She was my complete opposite when we first met, especially in terms of personality and outlook in life. She was more pragmatic, while I was more idealistic. Eventually we got used to each of our differences, but it also developed the way we were to adapt to each other. During the early years of our relationship, we had difficulty trying to understand or tolerate the polar differences between us. Some efforts led to one of us being either too distant or sensitive. I enjoyed the company of my companion a lot, but she did not feel the same level of likeness with my company, initially. As time went on, our personalities began to change towards each other’s differences. For example, my companion developed a softer and more caring personality, while I developed a more emotionally restrained and rational character. However, instead of swinging extremely to the opposite side, personality-wise, we developed a more balanced character between us. As a result, we get along better

How are women portrayed in the films of the 1960s and 1970s Essay

How are women portrayed in the films of the 1960s and 1970s - Essay Example The feminist beliefs differed from groups to groups and from one woman to another. By 1970s, the Second Wave Feminist Movements had inspired several men and women in the United States (Klinger, 2008). There was a change on the women perception in politics, media, private household and academia. Films produced in the 1960s and 1970s provide the best lenses upon which to perceive the depiction of the public on the role and status of women during the time. Dr. Strangelove, a film produced in 1964 is one such perfect film depicting the position of the woman in 1960s (Rosenstone, 2009). in the opening scene of the comedy, a member of staff of the United States Royal Air force is seemingly dressed to relax and flying above the Soviet Union. The member of US RAF whips out the latest playboy magazine and peruses through its pages. Whereas the actions in the short scene may not seem as a big deal, the scene optimizes the objectification of women that runs throughout the rest of the film. Stan ley Kubrick use satire in the movie to portray the lighter side of sad time on gender in the United States. Dr. Strangelove was produced during the period of Wave Feminism. While women of this period were allowed to vote, they lacked all the rights men held at the moment. Throughout this movie, women are either used merely for the benefit of men or are totally absent from the scenes. An excellent example of absence of women from matters important to the running of the nation is at the Joint Chiefs of Staff Meeting. There is not a single woman in the board rooms of the meetings that take a majority of the film. The quality of the film and the role of different genders in the movie portray the different perceptions of the people living at the time. Unlike present times where women take proactive part in cinemas, the 1964 production points to a time in history when women had not gained rights and respect (Rosenstone, 2009). They were not instrumental in the running of the state and mak ing important decisions of governance. Their role was supplementary to the duties of men. If a woman was to participate in any nation building activity, it would be under the shadow of her husband. Coming to the public limelight as an agent of change and constructive development of the nation was unheard of as depicted extensively in the film. While the services of women of the time were not directly outlined in the film, the role of women in satisfaction of basic needs of men was profound. Women were portrayed as objects of sexual satisfaction. The United States RAF pilot introduces this apparent place of women in the society of 1960s as he gets satisfaction from the Playboy Magazine by mere gaze at naked pictures of women. The first time the audience gets to meet a feminine character is with the entourage of Miss Scott. She echoes the director’s depiction of women as objects of sexual entertainment for men. Her sprawled out tuning under colored bright light in revealing bik ini leaving little to the imagination of the mind brings the point home that, indeed, women of the 1960s held no other position to men than massage their sexual ego (Klinger, 2008). The Graduate is the other film that tells gender and the way 1960s and early 1970s defined a change of the perception of both men and women on gender. The film narrates a story of two characters almost coming into terms with the dynamic meaning of gender at

HW1 - Essay Example (The administration of troubled President Al-Assad puts the amount of nationalities marginally higher, at 80 or more.) Conversely, the shows how the U.S government has not yet evaluated the amount of its nationals battling in Syria. The kind of data leaving the US includes reports of secluded occurrences, for example, in November 2013, when an administrator in the N.S.A proclaimed that three US nationals were confronting charges identifying with arrangements to make a trip to Syria to bond withthe Al-Nusra Front. Battling in Syria picking up across the board consideration in the Western press, authorities from the Parliament of Europe being compelled to remark on the dangers of joining in the battling, and the implications for the security of Europe. There are specific reasons for alarm with respect to what will take place provided remote contenders come back to Europe and their likely interest or association in suicide operation. Regardless of Benotmans declaration that a few Europeans may end up consuming jihad in the wake of going to Syria for different reasons, there are still numerous who end up radicalized by the dynamic vicinity of Islamist activist gatherings online prior to leaving for Syria. Online recruitment through social networking, web journals or sites on the Internet had gotten much simpler than some time recently. "To such an extent that the supposed third era of warriors inside the equipped gatherings grew up with engineering and are more connected with it particularly as keen gadgets and online networking sites have gotten across the board," he said. Online recruitment fights seem to have been compelling enough that a few governments in the West especially the U.S have propelled counter-battles accordingly. For instance In Dec 2013, The New York Times distributed an announcement by a United States State Department administrator who stated that a test case project would react to tweets, interpreted feature cuts show by

Defoe's Robinson Crusoe Essay Example | Topics and Well Written Essays - 500 words

Defoe's Robinson Crusoe - Essay Example However, Robinson Crusoe does not heed these warnings and sets out twice more on the sea. The first of these trips is to Brazil (without incident). The second and fateful trip which ultimately lands him on the desert island is the trade mission he engages upon to Guyana in Chapter 5 (Defoe, 1982). Once shipwrecked, without any shelter, dwelling, friends, comrades, family, amenities of a comfortable life, or supplies to speak of, Crusoe comes down with a high fever during a monsoon. This parallel to hubris and the utter humiliation of mankind’s best efforts is a direct parallel to the Greek writers nearly two thousand years prior to Defoe’s Robinson Crusoe. In this way, Crusoe experiences a Job like conversion and understands his hubris; therefore, he confesses his many sins of this life and sets out to read and study the New Testament with a renewed vigor. With the modern connection as it relates to Defoe’s Robinson Crusoe, the most obvious connection is to the film Castaway. Although the obvious connection is both works center around individuals who find themselves alone on a desert island, the parallels are far greater. The fact is that the underlying character development of both Castaway and Robinson Crusoe hinges upon the moment immediately following despair, self-loathing, hopelessness, and contemplations of death when the protagonists realize that this is their moment to define what they will do and how they will survive under difficult circumstances. Robinson Crusoe experiences a high fever accompanied by severe weather and a hallucination in which God speaks to him. On the other hand, Chuck Noland’s epiphany only comes after he opens the â€Å"forbidden fruit† of the FedEx packages washed ashore with him and finds useful items that can aid him in his quest for survival. In this way, both characters experi ence

Life's greatest miracle Term Paper Example | Topics and Well Written Essays - 750 words

Life's greatest miracle - Term Paper Example The producer of the program, Julia Cort notes that the urge to procreate is fundamental to all insects, birds, primates among others. DNA is a molecule responsible for carrying genetic material. It has been 4 billion years since the first discovery of this core molecule of life (Lifes Greatest Miracle). Bacteria replicate by cloning, that makes the parent and the clone identical with the exception of fornication mutants. Cloning as a type of reproduction is disadvantageous in that the species are prone to wipe out in case of a detrimental disease. Sexual reproduction on the other hand involves a male and female organism. Genes from each parent are vital for copulation to take place. The off spring from sexual reproduction is different from the parents and others. Sex results to difference. Variety is advantageous to a population because it translates to survival of a species. Sperm formation takes place in the testicles of a male organism with an approximation of 100,000,000 sperms per day (Lifes Greatest Miracle). Each sperm carries a unique genetic package. Miosis is the process that eggs and sperms undergo for them to exist (Lifes Greatest Miracle). The medical photographer explains the process with the aid of sex cells (egg and sperm). A pair of chromosomes in a sex cell replicate each forming two strands of chromosome attached at the centre. The chromosome then condenses to from an X shape. The partners coil around each other at specific points resulting to the transfer of genetic material. As mentioned earlier, sexual reproduction promotes diversity. Diversity increases the probability of organisms to survive. The narrator tells that majority of males start producing sperms during puberty while in females the creation of eggs onsets as a fetus. The eggs die off over the years. A teenage female outnumbers the adult female in terms of eggs in the ova ry. However, in comparison to a sperm, an egg is of quality rather

Comparison of the retail for Soda for Kroger and Circle K Essay

Comparison of the retail for Soda for Kroger and Circle K - Essay Example In comparison and contrast to Kroger, Circle K utilizes a much more aggressive level of advertising with respect to their own line of soft drinks. Publicity, direct marketing, sales and promotion, advertising, and interactive marketing all play a prominent role with respect to the degree and extent to which Circle K products are represented to the individual consumer within society. Interestingly, with respect to store design and display, Circle K helps to differentiate and separate the product that they are promoting as compared to Kroger. As such, rather than displaying Circle K’s line of soda directly alongside its competitors, it is represented within an entirely different section of the store; lending it to be understood/interpreted by the consumer as not only a replacement product but somehow incomparable. Once again, the retailer’s competitive advantage is with regards to low-cost. However, in addition to this low cost competitive advantage, Circle K is also able to offer the consumer with the tangential benefit of a great many different choices as compared to the

Development of Modern Transport Aircraft Essay Introduction This document is presented to compare the two commercially successful and super-efficient airplanes, the Boeing 707-320B and Boeing 787-9. This document will identify the key innovations in airframe and propulsion technology, and also further discuss on why the basic design and appearance of aircraft remain unchanged over 50years. Source: http://boeing.com/commercial/707family/product.html http://boeing.com/commercial/787family/787-9prod.html Innovations in Airframe Throughout the years since aircraft was created, engineers are constantly improving the efficiencies, durability and speed of its Airframe. From the beginning of 1920s, the all aluminium structures to the high-strength alloys and high-speed airfoils in the beginning of the 1940s. However as flying becomes more commercialised, people were not satisfied with just travelling at higher speed; they want to travel a longer distance with lesser fuel burnt! Hence, by the beginning of 1960s and 1980s, long-range design air frames and light weight composite researches were developed respectively. The materials used to construct airframe ideally require light, durable characteristics and at the possible lowest cost. The Boeing 707-320b airframe is constructed mainly using aluminium. The properties of having high tensile strength, light in weight, easily alloyed with other various metals, make aluminium very favourable in meeting the requirements of the aircraft construction. Many suggested that they would much rather fly a metal plane then a plastic one. However, as for Boeing 787-9, it is made up as much as 50% of composite material, approximately 32000 kg of carbon fiber reinforced plastic made from 23 tons for carbon fibre. These composites used to construct the B787 is not like any common plastic, it is stronger, lighter and offers greater strength to weight ratio than anything else. The boldly introduced airframe construction weighs 20% lighter than the conventional aluminium designs. This approach allows the airplane to carry more payloads and fly a further distance. In addition to the overall weight saving, moving to a composite primary structure also promises to increase resistant to fatigue and corrosion, reducing both the scheduled and non-routine maintenance burden on airlines.

The B707-320B uses 4 Pratt and Whitney JT3D engines. Each of these low-by pass engines could only produce 80kN of thrust. In the making of aircraft engines in the early generation, there were many constraints. Materials and technology were not developed and advance enough to overcome those limitations. On the other hand with mature technology now, the B787-9 uses a standard electrical interface that allows the aircraft to be fitted with either Rolls Royce Trent 1000 engines or General Electric engines. Each of these high-by pass engines produces 240 to 330kN of thrust. The aim of being compatible to these 2 models of engines is to save time and cost when changing engine types. Departing from the traditional aircraft design, the B787 also operates without the use of bleed air. The approach improves engine efficiency, as there is no loss of mass airflow and therefore energy from the engine, leading to lower fuel consumption. The B787 claimed to be 70% more fuel efficient than the company’s first 1950s-era four-engine Pratt Whitney JT3D-powered B707 and 20% more fuel efficient than the modern aircraft of the similar size. Basic Appearance The basic appearance and design of B787 appears unchanged from its predecessor B707. The basic swept wing, under-wing engine configuration has served as the basis for all of almost all of the new aircraft’s airframe. The reason is because the way how aircraft is going to fly and how lift is being created is not going to change considerably. Changes and improvements are often instead made on aircraft weight, performance, noise and passenger comfort. Source: http://en.wikipedia.org/wiki/Boeing_787_Dreamliner http://www.multilingualarchive.com/ma/dewiki/en/Boeing_787#Wirtschaftlichkeit Range Equation Breguet Range Equation [pic] †¢ V-Speed of aircraft †¢ L-Lift †¢ D-Drag †¢ G-Gravitional pull †¢ SFC-Specific Fuel consumption †¢ W-Weight (Reference to the equation above) With a given specific plan or profile, the Breguet Range Equation is used to calculate the aircraft’s range. We use this equation to predict and estimate the distance an airplane is capable to fly, accounting for its flight performance and the changes in weight as fuel is burned. The Specific fuel consumption is the measure on how efficiently an engine uses the fuel supplied to produce work. It allows engines of all different sizes to be compared to see which is the most fuel efficient.Using high by pass design and advanced materials, modern aircraft engine is able burn fuel more efficiently and overcome limitations in early generation such as high turbine temperatures. A decrease in SFC would mean an increase in range. Reducing the aircraft weight is always the goal for all aircraft designer. In case of B787, composite CFRP was boldly used up to 50% in the construction of the airplane. With reduced weight would means lesser thrust required. With lesser thrust would means decrease in fuel consumption rate. With a decreased fuel consumption rate, airplane will be able to fly a longer range. The lift to drag ratio refers to the amount of lift created by the aircraft, divided by the drag it produces when moving through air. Aircraft companies have been going towards the direction of achieving a higher L/D design; since a particular aircraft’s required lift is determined by its weight, delivering that lift with drag reduced, results directly to better fuel economy, longer range and at the same time a better climb performance and glide ratio .

Aircraft will be able to fly cheaper, faster and better.

British Petroleum: Unethical Issues

British Petroleum: Unethical Issues Referring few frequently use terms in business ethics as in, this report stressing on business ethics. Based on Crane and Matten in definition of business ethics, it is the study of business situation, activities, and decisions where issues of right and wrong are addressed. In a normal context, a situation cannot be considered unethical if it is not violating the law but a situation can be equivocal when conflict happened among ethical values. Importance of Business Ethics Ethical practices in business are important because businesss power and influence is greater than before. (Crane and Matten, 2010) Based on Laczniak and Murphy (1993, p. 5), consumer will have more impression on businesses that practice ethical practices in business. Based recent research of Belak and Rozman (2012), company that practices ethics will have better image and reputation. Then, it brings long term interest. Ethical practices help business to meet stakeholders expectations more effectively while stakeholders demand going more complicated and hard to achieve. (Crane and Matten, 2010) Based on the research of Holme (2008) on business ethics, he listed out few advantages of business in being ethical. He linked up the relationship between employee satisfactions levels with financial result of company. Higher satisfaction level of employee results in better financial result. Further, a company that practices ethics in business gains trust from suppliers. He further explained that a company practicing with ethical culture will influence employee to support on the company. It will influence employee to react with strong motivation and performance which is crucial to gain customer approval. Company Background British Petroleum, British  international  oil  and  gas companies headquartered London, UK. Based on CNNs Global 500 ranking of world corporations (Refer appendix B), BP ranked 4th largest company in the world and 3rd largest energy company. (Fortune, 2012) Nature of Business BP seeks to provide energy sustainably with its upstream and midstream active in 30 countries. BP works on finding, developing, and moving resources then produce and marketing the products. (Refer appendix C) Whilst providing energy and daily use products, BP investing on alternative resources, the sustainable energy with low carbon especially bio-fuels, solar and wind energy. Industrial Practices in Ethics As an international oil and gas company, decision made by the company often involve many parties and might brings serious consequences. There are ethics issues bothering BP in past few years, the human right and environmental issues. Based on BPs sustainability review of 2011, the company emphasize in enhancing safety and risk management in order to gain back trust from the previous accident in Gulf of Mexico. BP also continue working with safer drilling, avoiding environment pollution and restoring the environment resulting by deepwater horizon oil-spill. One of the industrial practices by BP in ethics is to treat people fairly and strictly eliminate child labour and forced labour. Bribery and corruption is prohibited in BP and the company seeks to not obey law. (BP Code of Conduct, 2011) BP invested in cleaner and greener energy helps preserving environment for future. Besides, BP  communicates with local community groups to avoid and minimize impact on their life. BP also helps in creating jobs. They use local suppliers and support community development. Ethical Dilemmas BPs stakeholders are the local communities, customers, employees, shareholders and analysts, governments and regulators, industry and non-government organizations. (Stakeholder engagement, 2012) In this case, stakeholder analysis is used to find out the interests of stakeholders affected by environment pollution caused by BP. How the environment pollution has impacted BP stakeholders will discuss later. Local Communities Based on an article of George in 2003, he emphasized the importance of taking interests of local communities while making decision. Supporting on local communities brings advantage of getting support from them in terms of supporting companys activities, as well as attracting and retaining good employees. Out of so many of the ethical issues, environment pollution is the issues that BP often encountered with. For example the Columbian pollution on farmland, Texas City chemical leak, and the recently deepwater horizon oil spill. The blowout of deepwater horizon rig in April 2010 has been commented as the worst oil-spill in history of US (BBC, 2010). The accident has killed 11 crew members on the rig and the rig sank two days after the explosion. The sank rig leak gallons and gallons of crude oil into sea and the leaking of oil from the exploded Macondo well polluted Gulf of Mexico and other 5 nearest gulfs, Mississippi, Florida, Alabama, Louisiana and Texas, causing environment pollution. The incident became the biggest issue faced by BP. Environment pollution that mostly faced by BP is the pollution caused by oil-spill. The pollution has caused damage on wildlife and eco-system of the impacted area. Wildlife like birds, sea turtles, dolphins, and also sperm whales were badly impacted because of oil-spill. There are health problems faced by these animals. Just to name a few, airways and immune system damaged because of oil-spill. Then, birds drown because of oil on their fur making them failed to fly. Dolphins found death because of the toxins released into the air. Marine mammals like dolphins need to go up surface and breathe. (Environmentalgraffiti, n.d.) Gulf Coast is rich with seafood like  fish, crab, oysters and shrimp, especially oyster and shrimp that are highly concentrated in the gulfs, contributing to production of seafood in US. The pollution affected the seafood industry badly. The 23% out of $2.4billions on production of Louisiana seafood has been shut down after the oil-spill. (Environmentalgraffiti, n.d.) Till date, there are still impacts on seafood found in affected coast even though oil has been cleared. Based on article of Jamail in (Aljazeera, 2012), they found fishes, shrimps and other seafood with abnormal growth. For example, eyeless fish and shrimp believe as a result of toxics released by oil. Tourism bears the brunt of the environment pollution. Based on a report of Oxford Economics (n,d), tourism plays key drivers in Gulf regions economy. Referring to the chart below, oil spill has greatest impact on tourism revenue during year 2010 after the Deepwater Horizon Oil-spill. Bourgeois, the owner of Bourgeois Fishing Charters told The Times-Picayune (2010) that his business was down after the oil-spill in Gulf of Mexico. The visit to fishing charters decreased about 20 percent after the case, booking declined and increase in cancellation rate of trips. Besides, fishing industry has been directly impacted by the pollution, causing increase of unemployment rate. The lives of people in affected gulfs were threatened because they were unable to collect fish. William, as reported by Juhasz (2012) article in The Nation, has lost his income because of shrimp he used to catch were affected because of the oil-spill. Air pollution caused by the explosion of rig also brings impact on the health of local communities. Nicole told The Nation that there is smell of oil for the entire month after explosion and it made her daughters asthma worst. Not only that, Elizabeth, 9, Nicoles daughter also suffers from rashes, allergies, inflamed sinuses, sore throat and an upset stomach. Another example of how environment pollution impact on BPs local communities is the oil-spill of Columbia pipeline caused by corrosion of pipeline. It is a project with Columbia national oil company and 4 others multinational company. The oil leaking from corroded pipeline transferring crude oil polluted farmland. Water was poisoned, lead to death of livestock and crops were failed to grow. (Taylor, 2011) Shareholders To be straightforward, shareholder as one of companys stakeholders to provided fund. (Harvard Business Review, 2012)  Shareholder seeks profit and return on investment rather than growth of business. The environment pollution of BP has brings impact on its shareholders. Especially the blow-out and oil-spill of deepwater horizon rig in Gulf of Mexico, BP faced numbers of court cases, claims and payout for cleaning up oil. BP has accepted to pay a total of $4.5bn fine to solve all the 14 criminal charges. (Goldenberg and Rushe, 2012) Besides, BP has paid a total of $23billions on claim and cleans up. Based on the report of BP on cash dividend payout in history, there is no dividend payout in year 2010 after the accident in Gulf of Mexico. Share price drop drastically from a constant increasing yearly. The dividend increased at 3rd quarter of year 2011 but it is still very much lower than the dividend paid before the accident on Gulf of Mexico. (BP, n.d) How BP dealt with dilemmas Dilemmas have to be solved by company to sustain in business. How BP did to solve the dilemma will be discuss and apply to ethical theory. Responding to the main cause of accident in Gulf of Mexico, BP has designed its programme on enhancing safety and risk management to avoid repeating of accident like Deepwater Horizon Oil-spill. Local Communities First, BP has takes responses to helps in different dilemma caused by the accident. It includes helps in monitoring health and safety of people involved in cleaning up oil, puts effort on cleaning up both offshore and on shore, rescuing and rehabilitation of wildlife, containing the leak and compensate the people and communities affected. (BP, 2011) Few examples on how BP responses to the dilemma, BP hired local commercial fisherman and vessel owner to help in clean-up. The clean-up of affected area need large amount of manpower and BP has decided to seek help from the local, with their local knowledge. Then, BP deployed new shoreline cleaning technologies. To stop the oil leaking from the damaged well, BP used dispersant to helps in stopping oil-spilling. (BP, 2011) To resolve the damage made to local ecosystem, BP has invested on monitoring wildlife, emergency restoration projects, early restoration projects and also National Fish and Wildlife Foundation Projects. BP works on minimizing and tracking for the impact on wildlife. For example, bird observational survey and live dolphin health assessments. Emergency respond also took by BP. For example, eggs of Kemps Ridley sea turtle has been collected and protected, release after hatchlings. (BP, 2011) Furthermore, BP supports on monitoring and testing programmes of seafood. This including testing on dispersants to boost people confident on the quality of seafood. As an overall till 2011, BP has invested $33.5 million to test and monitor the seafood, and $ 48.5 million to help in promoting seafood. (BP, 2011) With the affect on tourism industry because of the accident, tourism campaigns has launch to attract people visit to Gulf Coast. Event like seafood festivals and fishing tournaments has been launched and supported by BP in terms of funding. There is another advertising campaign launch by BP designed in promoting tourism. BP contributes in community development of the affected area. The company support on various type of jobs training, and education. (BP, 2011) Shareholders Ethical Theory (Utilitarianism) Utilitarianism, as defined by Bentham and Mill, the action is morally right if it results in the greatest amount of good for the greatest amount of people affected by the action. The theory also known as greatest happiness principle (Crane and Matten, 2010) Organizations best practices and values Alyeska Pipeline Service Company
