cingulate cortex of the participants were activated when they feel emotional pain same as physical pain. The subjects who had experienced recent social rejection were randomly assigned to take painkiller (acetaminophen) or placebo group for three weeks. As a result the participants in acetaminophen condition reported less hurt feelings in that three week period and it also observed that their anterior insula and the anterior cingulate cortex had shown less activation at the end of the treatment (Fogel

TLC is used because it is “sensitive‚ fast‚ simple and inexpensive analytical technique”2 (Mohrig 151). The unknown solid (unknown #3 in this case) used in the experiment was obtained and added to a 2.5ml of Ethanol/dichloromethane in a test tube. This was the solvent used in the experiment because Dichloromethane volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. The solid was already in powder form therefore we did not have

(Exhibit 2) The low-priced alternative also brings monetary value to aspirin users who might consider shifting to acetaminophen medicine because of the side-effect of aspirin. As patients still rely heavily on professional opinion in terms of medicine‚ pharmacies and physicians play an important role in influencing the choice of patients. By lowering the trade price

The Acetaminophen are less polar than the caffeine but more polar than the Aspirin and Ibuprofen and has average Rf value (0.4). The Aspirin has more Rf value (average 0.55) than the Caffeine and the Acetaminophen because it is less polar and travel with the solvent. The ibuprofen has the bigger Rf value in this experiment (average 0.7) because it has the lower
