Combustion Reactions

Combustion reactions are a type of chemical reaction in which a substance combines with oxygen to produce heat, light, and often other products. These reactions are essential for processes such as burning fuel, cooking, and powering engines.

General Equation

The general equation for a combustion reaction is:

fuel + oxygen → carbon dioxide + water + heat

Examples

For example, the combustion of propane (C3H8) can be represented by the following equation:

C3H8 + 5O2 → 3CO2 + 4H2O + heat

Another example is the combustion of methane (CH4):

CH4 + 2O2 → CO2 + 2H2O + heat
