Write a balanced equation for the combustion reaction that occurs between propane and oxygen. and limiting reactant

Hello!

The chemical reaction that occurs between propane (C₃H₈) and Oxygen (O₂) is the following:

C₃H₈ (g) + 5O₂ (g) → 3CO₂ (g) + 4 H₂O (g) + Δ

To really tell which reactant is the limiting one, you should know the amounts of each one, but generally, O₂ is abundant in the atmosphere and thus, propane would be the limiting reactant, as it is the one that is present in lesser amounts.
