GAS STOICHIOMETRY WORKSHEET
Please answer the following on separate paper using proper units and showing
all work. Please note that these problems require a balanced chemical
equation.

carbon monoxide reacts with oxygen at STP,
a. how many liters of oxygen are required to react?
b. How many liters of carbon dioxide are produced?
2. Acetylene gas (C
H
) undergoes combustion to produce carbon dioxide and
