TYPES OF REACTIONS!!!!! *boom*

Statement of the Problem:

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

Zn+CuSO4

C3H8

H2O2

Mg+HCl

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
