Given the balanced chemical equation, C4 H4 + 5 O2 → 4 CO2, + 2 H2O. If 0.3618 moles of

C4H4 are allowed to react with 1.818 moles of O2, and this is the only reaction which occurs, what

is the maximum quantity of carbon dioxide that could be produced?

We are given with the balamced chemical equation above that shows the combustion reaction of C4H4 and oxygen to from carbon dioxide and water. To determine the maximum quantity of carbon dioxide from the given reactant amounts of oxygen and C4H4, we determine first which between the two reactants is the limiting reactant. We divide each value to their corresponding stoichiometric coefficient. C4H4 has a smaller result (0.3618 vs. 0.3636 of O2), hence it is the limiting reactant. Taking the stoichiometric ratio of 1:4, the maximum quantity of CO2 is 1.4472 mole or 63.68 grams.
