Abstract: The purpose of this laboratory is to convert benzophenone to diphenylmethanol. This was done by using sodium borohydride to reduce benzophenone. The product was then crystalized from hexanes then using the melting point and IR testing it was possible to characterize it. The melting point range was… Introduction: This lab is possible because of oxidation and reduction reactions. In organic chemistry oxidation is the loss of electron density around a carbon‚ while reduction is an increase

darker-skinned people Eczema can also affect the pigmentation of one’s skin at an affected area in darker-skinned people. Although the direct cause of eczema is unknown‚ it is thought to be linked to an overactive response by the body’s immune system to an irritant‚ which in turn causes the symptoms of eczema. In addition eczema is commonly found in families with a history of allergies or asthma. Eczema “flare-ups” can be triggered by multiple substances or conditions. For example excessive heat‚ cold‚

Abstract The purpose of this paper is to introduce the reader to four different types of chemical weapons. The four types are choking gases and lung irritant agents‚ blister agents‚ nerve agents‚ and blood agents. The physiological effect of these weapons will play a big role in the effects of them. These weapons were used heavily during World War I and World War II. The weapons that will be described in this paper involve a lot of chemistry behind them so this paper also explores the chemicals
