Propane,C₃H₈,burns to produce carbon dioxide and water by the equation below.What is the coefficient in front of the carbon dioxide in the balanced equation? C₃H₈ + O₂ $\rarr$ CO₂ + H₂O

Quizplus · Accepted Answer

The coefficient in front of carbon dioxide in the balanced equation is 3. This is because the number of carbon atoms on the reactants' side must equal the number of carbon atoms on the products' side. There are 3 carbon atoms on the reactants' side, so there must be 3 carbon atoms on the products' side. The only product that contains carbon is carbon dioxide, so the coefficient in front of carbon dioxide must be 3.
