This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by 1 gram of the tablet was found. First‚ the two antacid tablets (Kremil-S) were crushed and weighed

Title: An investigation into the impact of group pressure on an individual’s estimate of the amount of beads in a pot (ginger granules in a jar). IV = Group/Individual DV = Individual beads estimate Abstract This experiment investigated the impact of group pressure on the individual. The hypothesis is that group pressure does indeed impact on the individual and in this case the individual’s estimate of the number of ginger granules in a jar. Participants were asked to make a judgement of

Experiment 9 Thin Layer Chromatography Experiment: 9 Title: Thin Layer Chromatography Introduction: Chemical analysis is conducted on specific analytes (specific substance of interest in a mixture)‚ however it is often found that these analytes must be separated for the chemical analysis to conduct their analysis. Chromatography is a set up of laboratory a technique that is used to separate a chemical mixture. This technique is very useful as it allows us to follow the course of

Title To determine the half-life of beer foam Purpose In this experiment‚ we will make the bear foam as much as possible by pouring fast and using warm beer and try to estimate the half-life of beer foam based on the changing of height while the foam is collapsing. Theory A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. Symbolically‚ this process can be expressed by the following differential equation‚ where N is the quantity and λ (lambda)

1--------------------------------------------------- Boston Beer‚ in response to consumers’ preference changes to more flavorful and bitter tasting brews‚ was founded in 1894. Boston Beer implements a “quality at any cost” strategy with a strong emphasis on product differentiation and implementing quality ingredients into its products. For instance‚ Boston Beer was the first company to employ a stamped freshness date on its bottles and ingredients are imported from around the world. Additionally‚ Boston Beer relies heavily on contract

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. Some also stated that do to the trust they had for the school and
