Reactions Lab

Lab Writeup
Types of Reactions:

Combustion: a violently exothermic reaction with oxygen to form oxides.

Single Displacement: where one element Is displaced in a reaction usually metal with another metal

Double Displacement: a reaction where two elements change positions in a reaction.

Synthesis: a chemical reaction in which atoms or simple molecules combine to form a compound that is more complex.

Decomposing: a chemical reaction in which a single compound is broken down to produce two or more simpler substances

Procedure:

1. Obtain 3 Small Test tubes.

2. In first test tube, place small amount of Zinc and about ½ mL ofCUSO4 Solutions.

3. In Second Test tube add about ½ mL Ba(NO3)2 solution to about ½mL of CUSO4 solution.

4. In third test tube place a piece of Magnesium Metal ribbon. Add then about ½ mL of HCL Solution.

5. Light a Bunsen burner. Record observations of the flame

6. Rinse out the first test tube. Add about 2 mL H2O solution. Lightly hear it, then record observations

7. Add a pinch of MnO2 to the h2o2 solution. Lightly heat and record observations

Chemical Equation Types of Reaction Observations

1. ZN + CuSo4 -> Cu + ZN(So4) Single displacement Formation of Copper

2. Ba(NO3)2+Cu(So4) ->Ba(SO4)+CU(NO3)2 Double Displacement Precipitation/Color

3. Mg + 2HCl -> H2 + MgCl2 Single Displacement Hydrogen Gas

4. C3H8 + 14O2 -> 3CO2 + 8H2O Combustion Flame, Water given off

5. H2O3 -> H2O + O2 Decomposition Two simpler molecules made

Discussion

In this lab we made several mixtures looking at what kind of reaction they are. In the results we found all of the possible reaction types but synthesis's. we were then able to determine many things from observing these types of reactions such as like wether the reaction was endothermic or exothermic.


Conclusion

We observed five reactions but only four of the five types of reactions were present in this lab, there where two single displacements, one double displacement, and one decomposition Our observations and such are shown above.
