Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.
The balanced chemical equation for combustion of methane is:
Reactants of a chemical reaction is defined as the substances which take part in a chemical reaction and undergoes a chemical change. Reactants are written on left side of the arrow.
Thus methane and oxygen are reactants of combustion reaction.
Products are defined as the substance which are formed at the end of the chemical reaction.Products are written on the right side of the arrow.
Thus carbon dioxide and water are products of combustion reaction.
