Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever)‚ as an analgesic agent (to reduce pain)‚ and/or as an anti-inflammatory agent (to reduce redness‚ heat or swelling in tissues). Chemically‚ aspirin is an ester. Esters are the products of reaction of acids with alcohols‚ as shown in the following equation using

Marriage and Kinship ties of Indian culture specifically of the village of Ratakote as told in Conformity and Conflict. The first thing I noticed about both cultures was they practiced arranged marriages with their children preferably being young (the Indians explained that young age was best so their children wouldn’t start becoming sexually active and elope with someone else they fell in love with and break off the entire marriage they were in). Both cultures were very close to each other family-wise

Describe the causes of culture shock... Culture shock Culture shock is basically defined as moving from a familiar culture to a one which are un familiar. Culture shock depends on factors such as how big the cultural difference is between your home and your new location‚ and how long one is away from home‚ you may or may not experience all the phases. There are many factors that cause culture shock like climate‚ food and language. One of the main reasons is climate

catalyzes the substrate molecule into a product. Enzymes have the capability to break or build compounds which keep cell systems functioning. For example‚ our digestive tract has catabolic enzymes which break apart food for storage and reuse. Our lab experiment studied the relationship of benzoquinone production when altering the pH and temperature of the reaction‚ as well as enzyme and substrate concentrations. We used a Spec 20 to evaluate absorbance at 540 nm. Absorbance represents rate of
