(1) Answer to Question in lab manual. NO introduction/background etc. 1. What is the retention time for caffeine? Retention time for caffeine : 4.149+4.142+4.152+4.1454 = 4.15 2. What is the retention time for benzoic acid? Retention time for caffeine : 2.651+2.817+2.857+2.9274 = 2.81 3. How are the retention times for caffeine and benzoic acid related to their chemical structure and the nature of the chromatographic

The hypothesis was rejected in this experiment‚ based on the results. The results were much different than hypothesized before the experiment. It was hypothesized that the lower concentrations of CLR‚ Jar E and Jar D‚ would be healthier and more likely to reproduce than the higher concentrations of CLR‚ Jar B and C. However‚ as shown in the actual results‚ Jar E and D with the lower concentrations of CLR died quicker than Jar B and C. The CLR and water solutions acted as a fertilizer‚ so the greater

Critical Thinking Stanley Milgram Experiment I feel the reason the Milgram Experiment subjects were lacking the moral and critical thinking of how they reacted to the experiment was a multitude of things such as. The subjects felt they had to because they were being told to by “people of authority” They also felt that since they were participating in the experiment and they were only doing “as told” then they were okay to proceed.

DESIGN AN EXPERIMENT: THE BIGGEST BLOWER EXPERIMENT Design an Experiment: The Biggest Blower Experiment Problem Statement: You have a pack of Hubba Bubba Bubble Gum. Does the amount of sugar in this gum affect the size of the bubble you blow?? Hypothesis: I think that sugar in any gum affects the size of the bubble you blow. I think this because I was watching “The Next Great Baker” and someone was melting sugar and when it cooled off a little he used a balloon blower to make bubbles out of
