Process

A Combustion Reaction is a reaction in which a substance reacts with Oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O₂ as one reactant. The combustion of Hydrogen gas produces Water Vapor: 2H₂(g) + O₂(g) → 2H₂O(g) Notice that this reaction also qualifies as a Combination reaction. Many Combustion reactions occur with a Hydrocarbon, a Compound made up solely of Carbon and Hydrogen. The products of the Combustion of Hydrocarbons are always Carbon Dioxide and Water. Many Hydrocarbons are used as Fuel because their Combustion releases very large amount of heat energy. Propane (C₃H₈) is a gaseous Hydrocarbon that is commonly used as the fuel source in gas grills. C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g)
