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

Life has its donwfalls‚ but those downfalls happen for a reason. Orphan Train by Christina Baker Cline is a book mainly about Vivians downfalls. This book changed my view of the world becuase it taught me about hope‚ and taught me about being grateful. This book taught me about hope because despite Vivian’s struggles throughout the book‚ she had pride‚ and something good came out of the bad events. For example‚ Vivian went through being enslaved‚ being sexually assaulted‚ and being neglected for

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

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

Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature
