tragic story of the Salem Witch Trial contains mass hysteria back in 1692. In my two articles “Salem Witch Craft Trial” and “Mass Hysteria in Upstate New York” have similar problems. In both articles I will be explaining how mass hysteria played a key role in both of these issues. In the article “Salem Witch Craft Trial” it tells the history of the mass hysteria behind the whole Salem witch craft trials. The mass hysteria occurred from 1692-1693 and lead to many people dying. There were one hundred

more mL of hydrogen peroxide‚ the reaction occurred again. Again‚ small bubbles formed; intensity of (1). The solution did not change in temperature. The reaction lasted about 15 minutes. 3. After adding more manganese dioxide‚ the reaction occurred again. This time‚ the bubbles being formed were larger; intensity of (4). The solution got a little warmer‚ but the difference in temperature was hardly distinguishable by simply touching the test tube. The reaction lasted about 10 minutes. 4. a) The

Jack London used several interesting craft moves in the “The Story of Keesh.” One craft move was descriptive words. Another was tone . Finally Jack London utilized long and short sentences to develop his theme that people are too quick to judge. Jack London made good use of descriptive words. One example of this is when he stated‚ “ ‘Na!Na!’ the men cried. ‘Put the child out!’ ‘Send him off to bed!’ ‘He is no man that he that he should talk to men and grey beards!’ ” This helps create the people

Friedel-Crafts liquid phase alkylation reaction of aromatic compounds is an industrially important which is known since 1877 and also commonly practiced in organic chemistry for the synthesis of various pharmaceutical compounds [1]. Catalytic benzylation of aromatics with benzyl chloride is one of the commercially significant C-C bond synthetic reaction processes to produce benzylated aromatics such as diphenylmethane and substituted diphenylmethanes. These are key intermediates in the synthesis
