Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

Dear Friends‚ I have been reading all your discussion posts‚ immensely informative indeed. For me‚ Plagiarism is copying any non-tangible asset (various art forms‚ text‚ design‚ lyrics‚ concepts etc.) without formally acknowledging the source. It is a paramount concern in the information age‚ calls for need of stringent laws for protection of intellectual property. It is a serious issue not only in the academia‚ but also sports‚ journalism and entertainment business. It poses serious questions

ABSTRACT The Stroop experiment focuses on the interference of a person’s reaction time on a given task. Certain tasks can be performed with more accuracy due to the fact that our brain becomes conditioned to react automatically after exposure of the stimuli. In this particular experiment‚ eight-teen college students underwent the Stroop experiment in individualized laboratory rooms. Four students were male and fourteen were females. The experiment helped us examine the horse race model

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

Argumentative Discussion of: Text a driver in New Jersey‚ and you could see your day in court According to an article written by Ben Brumfield and Chris Boyette from CNN‚ “Text a driver in New Jersey and you could see your day in court.” Texting someone while they are driving a vehicle could result in a lawsuit against the person texting for damages up to $150‚000. How can texting someone while they may be driving be held against you? What if the message was delayed somehow and didn’t get to

Opening and Closing a discussion If the opening speaker talks sense‚ he will get credit because he opened the discussion and took the group in the right direction. If‚ on the other hand‚ the first speaker’s start lacks substance‚ he will attract the undivided attention of the evaluators to his shortcomings. So speak first only if you have enough sensible things to say. Otherwise‚ keep yourself silent and let someone else start. Try and summarise the discussion at the end. In the summary‚ do
