INTRODUCTION AND BACKGROUND
Reasons For Lab:The purpose of this lab is to become more familiar with the five types of chemical reactions. In this lab we performed various chemical reactions. We then recorded our observations and then identified the type of reaction and wrote a balanced equation. The purpose of this lab is to become more familiar with the five types of chemical reactions.

Warm up: To warm up for this lab we took a series of quizzes until, on how to balance molecules.

Double Displacement Reaction
Reactions Types: Single Displacement- a metal and a compound switching metals, Na + HCl > H + NaCl; Double Displacement- Two compounds switching metals, NaCl + HF > HCl + FNa; Combustion- Rapidly combines with oxygen to form oxide and release energy, C2H6 +O2 > CO2 + H2O; Synthesis- Combination of two to form single product, Na + Cl > NaCl; and Decomposition- Break down of single compound into smaller objects, NaCl > Na + Cl.



Materials: Aprons, Goggles, Bunsen Burner, Test tubes, Zinc, CuSO4, Ba(No3)2, CuSO4, Magnesium Ribbon, HCl, H2O2, MNO2, Lighter, C3H8 (propane), Wooden stick, and an appetite for reactions!
Decomposition reaction


Safety: Well since in this lab we had hazardous chemicals and open flames. We were required to wear aprons, goggles, and of course close toed shoes. Also we had to take special precaution in mind not to sniff and or ingest the chemicals.

Procedure:

First, We Obtained 3 small test tubes. In the first test tube, we place a piece of Zinc and about 1/2 ml of CuSO4 solution. We recorded our observations. In the second test tube we added about 1/2 ml of Ba(NO3)2 solution to about the same amount of CuSO4 solution. we recorded our observations. In the third test tube we placed a piece of magnesium ribbon. Then we added about 1/2 ml of HCl solution. We recorded our observations. Next, we lit a bunsen burner, burning propane gas (C3H8). After cleaning out our test tubes, we added about 2 mL of H2O2 solution. We lightly heated it and recorded our observations. Then, we added a pinch of MnO2 (catalyst) to the H2O2 solution. We lightly heated it again and recorded our observations.

Results: Data Table

Balanced Equations:

Experiment 1. Zn + CuSO4 > Cu + ZnSo4


Experiment 2. Ba(NO3)2 + CuSO4 > BaSO4 + Cu(NO3)2

Experiment 3. Mg + 2HCl > H2 + Mg(Cl)2

experiment 4. 2H2O2 > 2H2O + O2

Experiment 5. 2H2O2 > 2H2O + O2


Conclusion:
Through this lab we have become more familiar with the five types of chemical reactions. Using our prior knowledge of equations we have determined which of our experiments produced which of the five chemical reactions. We are henceforth better at chemistry, computers, following instructions, and therefore life.
