Actual yield/Theoretical yield x 100 (0.5/0.68) x 100 = 73.5% Conclusion: The objectives of this experiment are to predict the amount of product produced in a precipitation reaction using stoichiometry‚ to accurately measure the reactants and products of the reaction‚ to determine the actual yield vs. the theoretical yield and to calculate the percent

The aim of the experiment was to examine the effects that having a rich lipid diet had on the CHO and fat metabolism during the prolonged exercise. The data shows that at rest the body was in a heavy fat metabolism and when exercise started there was a shift of metabolism from fat to CHO. After thirty minutes‚ the metabolism shifted back to a primary metabolism of fat. Examining the data from this experiment to other studies showed a similar result.

ABSTRACT The study us experimenters re-conducted was based on Norman Triplett’s study of social facilitation and how social presence or encouragement improves an individual’s speed and consistency in their performance. The experiment was replicated in using several trials for accurate results and was split into two stages: a mental challenge and a physical challenge. The two male and two female participants ranged from ages 15 to 17 years old. For the mental challenge‚ each participant was pulled

Daphnia Experiment Report 1. Introduction Caffeine is found in many plant species‚ where it acts as a natural pesticide. It is found most commonly in cocoa‚ tea and coffee‚ but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans‚ caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure‚ restlessness‚ insomnia and anxiety which‚ in
