Chemical Reactions Lab Report
Introduction:
Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis, decomposition, single replacement, double replacement, and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition, it is the opposite where a product breaks down into reactants. In Single Replacement, reactants switches an element with another element to make a new product. Then, in Double Replacement, two reactants switches an element or compound to make a two new products. Lastly, for Combustion, it is when oxygen and a hydrocarbon react to create water and carbon dioxide. In this experiment, we were meant understand and explain what a reaction were to look like in real life and see patterns in reactions. We did reactions between Copper metal, Magnesium metal in fire for a synthesis reaction. Silver nitrate and Copper metal and Zinc metal and Hydrochloric acid for a single replacement reaction. Nitric acid and sodium hydroxide, nitric acid and sodium carbonate, and
I felt this purpose was accomplished, because I was able to see examples of synthesis, single replacement, double replacement, and combustion. I concluded that in some double replacement reactions, there can be a result of a precipitate, for example between Barium nitrate and Sodium hydroxide there was a product of a form of salt. This experiment was probably not very reliable due to the fact, the reactions were not done over again and double replacement was not done at the same time as the other reactions. If I were to do this experiment again, I would try to do each reaction three times and make sure each reaction is completed on time. This experiment is significant, because it is a stepping stone towards future experiments with
