This lab shows different types of reactions in chemistry. The five basic reactions are synthesis, decomposition, single displacement, double displacement and combustion.
Procedure:
1) Equip safety gear like an apron and goggles.
2) Obtain 3 test tubes.
3) Place a piece of zinc in a test tube along with some CuSO4 solution and record results.
4) Place 0.5 mL of Ba(NO3)2 and CuSO4 in the second test tube then record your results.
5) Put magnesium and HCl in the third test tube and record your results.
6) Light a bunsen burner and record your observations of the flame.
7) Rinse out the 1st test tube, add H2O2, lightly heat it and record your results.
8) Add MnO2 to the H2O2 and record your results.
| Mixture | Analysis |
| Zinc + CuSO4 | Turned shiny and had bubbles |
| Started to accumulate copper | |
| CuSO4 + Ba(NO3)2 | Started bubbling and turned white |
| White powder formed at the bottom of the test tube | |
| HCl + Mg | Formed bubbles, got hotter and turned shiny |
| constantly bubbles and puts out the fire quickly | |
| propane fire | combustion reaction, with blue flame |
| H2O2 + heat | forms multiple bubbles |
| H2O2 + MnO2 + heat | MnO2 acts as a catalyst and causes even more bubbles to form |
Zn+CuSO4--> Cu+ZnSO4
Ba(NO3)2+CuSO4--> BaSO4+Cu(NO3)2
Mg+2HCl--> H2+MgCl2
2C3H8 4O2-->3CO2+8H2O
2H2O2-->2H2O+O2
