Our goal is to be able to preform the different chemical changes, distinguish what kind of chemical change happened by our observations and be able to identify the products.
Materials:
In this lab we needed safety gear (goggles and apron), test tube rack, 1-3 test tubes, bunsun burner, sparker, clamp, reactants ( piece of zinc, about 1/2 mL CuSO4 solution, about 1/2 mL Ba(NO3)2 solution, about 1/2 mL HCl solution, magnesium ribbon, about 2 mL H2O2)
Procedure:
1. Obtain three small test tubes
2. in the first test tube,place a piece of zinc and about 1/2 ml of CuSo4 solution. Record observations.
3. In the second tube add about 1/2 ML Ba(NO3)2 solution to about 1/2 mL of CuSO4 solution. record observations.
4. In the third test tube place a piece of magnesium ribbon. add about 1/2 mL of HCl solution. Record Observations.
5. Light a Bunsen burner (burning propane gas, C3H8). record observations.
6. Rinse out the first test tube. Add about 2 mL H2O2 solution. lightly heat it. Record observations.
7. Add a pinch of MNO2 (catalyst) to the H2O2 solution. Lightly heat it. Record observation.
Results (Data):
| Reactions | Product | Observations | Reaction Types |
| Zn+CuSO4 | ZnSO4+ Cu | Brown precipitate, copper formation | Single Displacement |
| Ba(NO3)2+ CuSO4 | BaSO4+ Cu(no3)2 | Milky white/blue liquid, white precipitate, cold, color change | Double Displacement |
| Mg+HCl | H2+ MgCl2 | Clear bubbles, Heat, Hydrogen gas released (popping explosion) | Single Displacement |
| C3H8+O | Co2+ H2O | Lit on fire when spark was added | Combustion |
| H2O2 | H2O+ O2 | Making popping boiling, Oxygen gas released (splint got brighter) | Decomposition |
C3H8
H2O2
Conclusions:
* Include a sum
mary of the data - averages, highest, lowest..etc to help the reader
understand your results
* List one thing you learned and describe how it applies to a real-life situation.
*Discuss possible errors that could have occurred in the collection of the data
*answer discussion questions
