Gaseous methane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water. What is the theoretical yield of carbon dioxide formed from the reaction of of methane and of oxygen gas?

The theoretical yield of carbon dioxide formed from the reaction of methane and oxygen gas is 1 mol.

Explanation:

The equation below shows the reaction of combustion of methane:

CH₄ (g) + 2O₂ (g) → CO₂ (g) + 2H₂O (g)

When no reactants are wasted and the reaction is complete, 1 mol of gaseous CO₂ will be produced. This means that the theoretical yield of carbon dioxide is 1 mol.
