description on acid rain as well as a focus on acid rain in eastern Canada. This report contains a very helpful basic background on acid rain as well as a questionnaire. It involves an annual report on the Federal-Provincial Agreements‚ sulphur dioxide emissions in the seven most eastern provinces‚ trends in acid deposition in the Atlantic provinces from 1980-1994‚ as well as acid precipitation in Kejimkujik‚ Nova Scotia. It also includes data tables‚ graphs and interesting facts concerning acid rain.

The Effectiveness of Phosphoric Acid on Meat Chapter I. Introduction A. Background Of The Study This experiment was performed to find out if the acidity in Coca Cola could dissolve meat. The testing was done by placing pieces of pork‚ chicken breast and salmon into bowls filled with Coca Cola‚ and observing meat for 5 days. Coca Cola is a popular carbonated beverage that is sold in more than 200 countries. Also known as Coke‚ it can be purchased from vending machines‚ department stores and

What Causes Acid Rain? {2} {2} Acid rain caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into air. These substances can rise very high into the atmosphere‚ where they mix and react with water‚ oxygen‚ and other chemicals to form more acidic pollutants‚ known as acid rain.{2} Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by wind. As a result‚ the two compounds can travel long distances where

April Goodson CHEM 242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much

Lab 12: Titration of Acetic Acid in Vinegar Abstract: To lesarn how to titrate chemicals in a lab. Also to be able to determine the concentration of an acetic acid solution. Purpose: To learn how to titrate‚ and calulate the concentration of an acetiuc acid solution. In this case the concentration of vinegar‚ which is diluted acetic acid. Hypothesis: The sodium hydroxide used in this titration would balance out the acetic acid in vinegar. The phenolpthalein‚ a acid –base color indicator will

and sought to discover which ratio of an acid and base reaction produced the most amount of carbon dioxide gas (CO2) without leaving leftover reactants. 5 varying amounts of bases were added to a constant amount of acid (10 ml) to better understand which ratio was the most efficient. RESULTS Data collected from the lab suggests that the ratio of acid to base that produced the most carbon dioxide gas (CO2) was 1:0.5. This means that for every one mole of acid‚ 0.5 moles of base would be added. The

Conjugated linoleic acid‚ is a form of linoleic acid‚ an omega-6 fatty acid important to human health (Wang and Jones‚ 2004). The CLA is formed by the bacteria in rumen of certain ruminants but not for humans. It is obtained by humans from dietary sources such as beef‚ lamb and dairy products including milk and cheese (Wang and Jones‚ 2004). CLA is an antioxidant‚ anti-carcinogenic‚ anti-diabetogenic‚ anti-atherosclerotic‚ anti-catabolite as well as an immune system enhancer (Belury‚ 2002). Health
