Combustion Equations

Balanced chemical equations for complete combustion of hydrocarbons are needed to calculate reactant and product quantities.
Examples of hydrocarbons include methane, butane, hexane, ethanol, propanol, and hexanol.
Complete combustion requires oxygen gas as a reactant.
Products of complete combustion are carbon dioxide and water.

Calculations from Equations

Quantities of reactants and products can be determined using balanced chemical equations.
This is applicable to combustion equations, where quantities of reactants needed or products formed are of interest.
