Quizplus · Accepted Answer

The number of carbon atoms on the reactant side must equal the number of carbon atoms on the product side. There are 5 carbon atoms on the reactant side, so there must be 5 carbon atoms on the product side. The only product that contains carbon is carbon dioxide, so the coefficient in front of carbon dioxide must be 5.
