Acid Rain: The Southern Company (A) Case Study #1 2/01/2012 Situation: The acid rain provisions of the 1990 amendments to the Clean Air Act were to being in 1995. Currently‚ it is 1992 and The Southern Company (a electric utilities holding company operating in Georgia‚ Alabama‚ Mississippi‚ and Florida) had to decide what actions they were going to take in order to comply with the new regulations. Before the Clean Air Act‚ firms did not have incentives to reduce emissions below the government

A Swiss chemist named Dr. Albert Hoffman first produced lysergic acid Diethylmide or best known as LSD in 1938 (Dye‚ 1992‚ p. 2). Hoffman discovered the drug while trying to synthesize a new drug for the treatment of headaches. He obtained the lysergic acid from the parasitic fungus that grows on rye plants known as ergot. From the lysergic acid‚ he synthesized the compound LSD. He used the compound to test for its pain killing properties on laboratory animals. Being that appeared totally ineffective

To determine if the reaction had gone to completion‚ a Starch/Iodine test was conducted. A change in the strip to a deep blue color would signal an excess of sodium hypochlorite reagent present. An excess is the reagent symbolizes the end of the reaction because there is no longer any reactant left to consume reagent. After the reaction was deemed completed‚ the product was isolated and purified by ether extraction‚ aqueous extraction and evaporation. To determine how sodium hypochlorite acts as

The Role of the Citric Acid Cycle The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation‚ and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis‚ which also occurs in anaerobic

Tests for Carboxylic Acid and Derivatives Mary Catherine Sarte‚ John Emmanuel Sy‚ Allurie Umel‚Franklin Yap‚ Mary Christine YouIntroduction Carboxylic acids derivatives are simply groupsof compounds that contain a carbonyl group butwith an electronegative atom attached to thecarbon. The difference in the structure leads to amajor change in reactivity. The reactions of thesegroups of compounds involve nucleophilicsubstitution. Although there are abundant kindsof carboxylic acid derivatives‚ the experimentonly

Acid-Base extraction theory states that when an acid reacts with an organic base it results in a salt that is water-soluble and a neutral molecule that is insoluble. The addition of an acid to a mixture containing acids and bases will result in the acid remaining unchanged and the base reacting to form a salt. The results from the experiment were fairly consistent when separating the strong acid‚ weak acid‚ or the base. In part one of the experiment‚ you had to separate the strong acid. When added
