Objective -
Perform 2 different types of chemical reactions

Experiment -
Part 1 – Heating Baking Soda
Place a small scoop of baking soda in a clean and dry test tube .
Mass of test tube with baking soda = _______ g

Begin heating the test tube and collect the gas in the inverted test tube produced from the reaction.
Results of burning splint test on the gas.
Keep heating until no more gas is produced.
Mass of cooled test tube after heating = ___________ g

Part 2 – Zinc + Aqueous Hydrochloric Acid
Results of burning splint test on the gas.

Analysis –
1. Write a chemical equation for part 1. Water, sodium carbonate and a gas (that you tested) were produced.
2. Write a chemical equation for part 2. Zinc chloride and a hydrogen gas was produced.
3. Balance the equations in analysis 1 and 2
4. Classify equation 1 and 2 into one of the five reaction types we have discussed.
5. Calculate the mass difference in the test tube for part 1.
6. Why is the final mass of the test tube in part 1 different from the beginning?
