Chemical Reaction Lab

A chemical reaction is a process in which one or more reactants are converted into products.

Chemical reactions are classified into five main reaction types: synthesis, decomposition, single replacement, double replacement, and combustion. The type of chemical reaction can also be classified in one of two ways: oxidation-reduction or non-oxidation-reduction reactions. Based on my recollecting of prior knowledge and recent studies to obtain background information for this particular lab, I was able to design a hypothesis that I feel incorporated the main aspects of my background information. My hypothesis stated: : if evidence of a chemical reaction is detected when certain chemicals are combined, then we are able to categorize such reactions

Our unanticipated event developed when we were experimenting with Zinc and Hydrochloric acid. Before attempting to perform this particular part of the experiment, my partner and I rechecked and examined any and all directions and/or procedures that were presented to us. We were aware that when we combined the two elements ( Zinc and Hydrochloric acid) we were essentially collecting hydrogen gas that was evolved in the test tube and if performed correctly, on ignition, it burned with a “pop” sound. Hydrogen is a combustible gas, and factors such as heat evoke a diminutive explosion, thus creating the “pop” sound. Although my partner and I followed the instructions to the best of our ability we were unable comprise the proper reaction because we had not allowed enough time for the minimum collection of hydrogen gas to occur. Thus being said, if my partner and I were to perform this lab for a second time, we can agree that to improve our experiment results we would focus more on the chemical reaction that included zinc and hydrochloric acid, for this is the chemical reaction that we were not able to collect proper data and configure our results for. If we were able to re conduct only this part of the lab, based on previous experience, we would allow more time for the hydrogen gas to collect in hopes that adding a catalyst ( in this case heat) would evoke a reaction thus ensuring a

I feel as though if I were to improve on this I would be able to more easily decipher between the overall differences and comparisons that were evident in each chemical reaction. By doing this I also would be able to more precisely observe and explain how each product and/or reactant was affected when combined to create something
