Combustion Reactions

Combustion is a chemical reaction in which a substance reacts rapidly with oxygen and releases heat and light. The most common example of a combustion reaction is when a fuel, such as wood, gasoline, or natural gas, reacts with oxygen in the air to produce carbon dioxide and water vapor. This type of combustion is known as a complete combustion reaction.

The general chemical equation for a combustion reaction is:

fuel + oxygen → carbon dioxide + water + heat + light

For example, the combustion of methane (natural gas) can be represented by the following chemical equation:

CH₄ + 2O₂ → CO₂ + 2H₂O + heat + light
