Yield Essays

this experiment was a slightly yellow tinted liquid. The percent yield was 28.99%. This is indicative of a successful product. This percentage indicates, not only was product formed, but the correct amount of anhydrous sodium sulfate was added, which removed the water molecules from the product. Another factor contributing to the percent yield is the amount of time the product was left under gentle air. A higher or lower percent yield would have suggested an incorrect amount of anhydrous sodium sulfate

percent yield possible. Percent yield is the percent ratio of actual yield to the theoretical yield. % yield= (Actual yield)/(Theoretical yield)×100% Where the actual yield is the amount of product actually produced in a chemical reaction in grams, theoretical yield is the amount of product obtained from the stoichiometry or balanced equation using the limiting reactant to determine the product. Units for both actual and theoretical yield need to be the same (moles of grams) (”Percent Yield Definition

1. What was your theoretical yield and your percent yield? Theoretical yield: 3.9151 g Percent yield: 79.30% 2. An accurate percent yield must be below 100% Why? (2-3 sentences) First, percent yield cannot be over 100% because mass cannot be created; the collected mass of a substance can never go over the theoretical yield of that substance. Percent yield is also very rarely 100% because no equilibrium reaction, which is the type of reaction studied in this lab, can go to completion. There

Before proceeding with the experiment, the theoretical yield was calculated to be 0.945 g. After preparation of the product, the theoretical yield was used to determine the percent yield, which was found to be 79%. Due to this reasonable yield, it was concluded that the synthesis of methyl orange had been successful. Data Table 1 gives the results and observations that were recorded throughout the preparation of methyl orange. According to literature, methyl orange is an azo dye that forms orange

121 g⁄mol C_7 H_6 O)×5.02g, equaling to, 5.78g±0.01g of benzoic acid. To calculate the percentage yield, Equation #1, would be used, and the observed mass of benzoic acid, as stated in Table 1.1, is 5.68g, with the maximum benzoic acid possible to be 5.78g, as calculated using Equation #2. Thus, Equation #1 with the key information would look the following, 5.68g/5.78g×100%, equaling to a 98.3% yield, as shown in Table 2.1.

There is no doubt that today’s society is pushing the limits of Earth. Through oil drilling in the Middle East to the increasing amounts of pollution found in China, it is only a matter of time when the citizens of Earth will begin to feel the effects of reaching our carrying capacity. Carrying capacity is limited to the maximum population size and resources an environment can hold and sustain indefinitely. For example, the movie, Human Population Dynamics discusses the idea that all 6.5 billion

As only 4.3mL of ester was collected, there was a poor yield of ester in this experiment. This may have been because the amount of reactants used was too little (i.e. only 10mL of each), and thus, a greater yield of ester could not be produced. Moreover, the reflux time of 40 minutes may have been too short, and did not allow a long enough period for a sufficient volume of ester to be produced as they reactants were vapourised and condensed back into the pear-shaped flask to react. Additionally,

1) Percentage yield experiment: First we measured 20cm3 of sulphuric acid into a beaker using a measuring cylinder, this will help us determine the percentage yield at the end of the experiment. We then heated the beaker containing the sulphuric acid using a Bunsen burner in order to heat it up for the copper oxide to mix with. We then weighed out 1.02g of copper oxide and added it to the acid and stirred it whilst doing so, we did that until the liquid turned blue, this proves that the chemicals

Title: Using Four Reactions to Calculate the Percent Yield of Recycled Aluminum Author Information: *Mia Ingram, Tyler Snody (*Primary Author) CHEM 111, Section 511, Experiment 4: The Chemistry of Recycling Introduction Aluminum is a common and crucial metal used in consumer’s everyday lives. It is mainly used in making containers and packaging, car parts, aircrafts and other household items. Recycling aluminum, usually in the form of cans, requires very low energy in order to make a useful product

Market structures describe the competitive environment in which a firm operates. The characteristics of the market structure will have a major-influence on the competitive strategies and tactics that are implemented by firms. (Octotutor, 2014). For the purpose of this analysis, I have chosen to analyze the Coco-Cola Company, which operates in an oligopoly. This type of market has many implications for both consumers and competing firms. Coca-Cola Company is one of the premier global consumer brands

1.2. Product Differentiation This refers to differentiation that aspires to make a product more attractive by contrasting its unique qualities with other competing products (Investopedia, 2015:1), as in the case of Coca-Cola, other soft drink brands. Successfully adopting this strategy would have a company gaining a competitive advantage, as the customer would then view the product as unique or superior. This is what coca cola has managed to do, and has managed to do it on a scale that is globally

Executive Summary Throughout this assignment, the company activities, structure, management accounting functions and contributions to modern management accounting of Unilever Plc has been stated clearly. Unilever Plc is one of the world’s largest manufacturers of transnational consumer and founded in the year 1929 after the combination of two companies. It is a multi brands company which having more than 400 brands and involving in producing food, beverages, personal care and home care products.

In this experiment, I carried out a hydrolysis reaction by isolating trimyristin to yield myristic acid and glycerol as a side product. The trimyristin was prepared by combining ground nutmeg and diethyl ether and heating the mixture under gentle reflux. The mixture was then washed and concentrated in a rotary evaporator, obtaining crude trimyristin, which was then purified via recrystallization with 95% ethanol. This yielded 0.230g of purified trimyristin, in the form of a white powder. The trimyristin

Balance Sheet vertical Analysis: Costco’s long-term debt was 5.1% of their original asset in 2012; it is increased to 14.5% of their total assets in 2015. During the past four years, Costco Wholesale Corporation had a 9% increase in their long-term debt as shown on the vertical analysis of the balance sheet. There are few main causes to this change. Firstly, In December 2012, Costco issued $3,500 million of Senior Notes to fund the business, these notes are payable in 2015 2017, and 2019. Secondly

Susurros de Mi arrabal is literarily a fiction/generational history fiction story book written with the purpose to entertain, educate future generations and probably help Puertorricans enjoy a little bit of their own cultural traits, language, ethnic, folklore, music, perhaps food and most important of all, their Love and their life. Every country has changes and challenges related to their generation, the economy, politics etc.; as well as ethnical traits, their idiosyncrasy, their religious beliefs

The Industry that we are studying is about the passenger vessels that are travelling directly from Cebu to Manila vice versa. Big names in travel firms such as 2GO Travel (a part of 2GO Group) and Sulpicio Lines (Philippine Span Asia Carrier Corporation) have their passenger vessels travelling at the same route. This specific market has a competition not just only by vessel but also in air travel and from the other provinces that have buses who goes to Manila. The competition on the same type of

In today’s day and age, everyone wants to have their dream job and so they work extremely hard to make it to the top. However, people are not always sure the impact that their dream jobs can have on their personal lives. The movie Devil Wears Prada is a movie that showcases what happens to a young woman when she decides to join the fashion brand Runway as the assistant of Miranda Priestly, the editor in chief of the Runway magazine. In the movie, the young woman, Andy, is often faced with difficult

Now the cars have more technologies than the ole models. The modern vehicles embedeed with marvellous engineering, but the people might be worried about driving the cars by understanding all of its modern features. The too much techology in new cars can result to be a bad scenario. According to the recent analysis, many people share their opinion that the maodern cars are becoming too much complicated and making it more annoying in different ways. But the goal is, when you're in a car, you still

Exercise 5.1 1. What are the yield ratios for each step in the recruitment and selection process across all recruitment sources? What are the implications of these ratios for future hiring? Could you also calculate a yield ratio for a particular recruitment source? Why would that be helpful to do? Total number of applicants=633. Recruitment process Applicants Yield ratio Potentially qualified 149 149/633*100=23.5% Interview 105 105/149*100=70.5% Qualified & offered job 89 89/105*100=84.8% Accepted
