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

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

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

The essential part in this practical is to plan the experiment in detail in order to obtain substantial data. Firstly we have to identify our controlled variables which will be kept constant throughout the experiment. By carrying out this practical it is ideal that students

Unfortunately‚ we did not have any data for week four due to the Astros parade‚ and during the fifth week of data collecting‚ two nightcrawlers went missing during the experiment in one of the containers‚ so the results for the Gain at 0.06% were inaccurate and the six week mass count as shown in figure one‚

community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine revealed that the primary bacteria

Abstract The Tuskegee syphilis experiment was an infamous clinical study conducted between 1932-1972 in Macon Country‚ Alabama by the U.S Public Health Service. The purpose was to study the natural progression of untreated syphilis in rural African American men who thought they were receiving free health care from the U.S government; about four hundred African American men were denied. The doctors that were involved in this study had a shifted mindset; they were called “racist monsters”; “for
