requires immense exertion and along the way many will face obstacles that are not simple to overcome. In "A World Lit Only By Fire‚" by William Manchester‚ Desiderius Erasmus‚ a daunting humanist scholar‚ is told to have risen up against the Catholic superstructure in an attempt to keep Christendom intact. Erasmus ’ disdain for the Catholic church not only helped himself but opened the eyes of many people. The people of this time were not only naive but were followers of the church only because they believed

Introduction The parade of corporate accounting scandals of the last decade‚ with lion’s share occurring in 2002‚ has developed deep antipathy and distrust towards corporations and their reporting practices‚ and casted doubts on the opinions of audit firms. As majority of these accounting frauds occurred in the US (See Appendix)‚ there was a widely-held view that rules-based accounting standards have allowed failure of large corporations like Enron and World Com‚ since US GAAP is perceived to

BasesLewis acids and bases play an important role in chemical reactions because‚ except oxidation-reduction reactions‚ almost every reaction could be categorized as an acid-base reaction. Bases in water solutions show certain specific characteristics: bitter taste‚ feel slippery‚ and turn litmus paper blue. Acids in water solutions show these most common characteristics: sour taste‚ react with metals‚ and turn litmus paper red. The understanding of chemical reactions‚ such as acid and base interactions‚

Two key factors that contribute to the ease of deprotonation are the polarity of the H—A bond and the size of atom A‚ which determines the strength of the H—A bond. Acid strengths are also often discussed in terms of the stability of the conjugate base. Sulfonic acids‚ which are organic oxyacids‚ are a class of strong acids. A common example is toluenesulfonic acid (tosylic acid). Unlike sulfuric acid itself‚ sulfonic acids can be solids. Superacids are acids stronger than 100% sulfuric acid. Examples

CHEMICAL REACTIONS: ACID-BASE BUFFERS Short Overview Acids and bases represent two of the most common classes of compounds. Many studies have been done on these compounds‚ and their reactions are very important. Perhaps the most important reaction is the one in which an acid and base are combined‚ resulting in the formation of water (in aqueous solution) and a salt; this reaction is called neutralization. A buffer solution is a solution that contains both an acid and a salt
