Question: A combustion reaction involves the reaction of a s... A combustion reaction involves the reaction of a substance with oxygen gas. The complete combustion of any hydrocarbon (binary compound of carbon and hydrogen) produces carbon dioxide and water as the only products. Hexane is a hydrocarbon that is found in gasoline. Complete combustion of hexane produces 6 L of carbon dioxide for every 7 L of water vapor (both measured at the same temperature and pressure). What is the ratio of carbon atoms to hydrogen atoms in a molecule of hexane? (Simplify your answer completely.)
