Emotional and Rational Appeals Abstract In many studies‚ data has been led to suggest that rational messages may encourage the generation of content based cognitive responses and lead to attitudes heavily influenced by these cognitions. Studies have also led to suggest that people in negative moods are affected by the quality of persuasive messages. Using manipulations techniques‚ bad mood may result in a different interpretation of anything from a verbal argument to a literal message. Even though

Lab Report Synthesis and Characterization of Aspirin (Acetylsalicylic Acid) The Synthesis and Characterization of Aspirin (Acetylsalicylic Acid). Summary: In this experiment‚ we produced 4.21 g of acetylsalicylic acid. Our theoretical yield was calculated to be 5.22 g. Therefore our % yield was determined to be 80.6%. The experimental boiling point range of acetylsalicylic acid was found to be 130-132° C. The true melting point of acetylsalicylic acid is 135° C‚ therefore our percent

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic
