The type of reaction you're referring to is a combustion reaction. In a combustion reaction, a substance (often a hydrocarbon, which is a compound made up of carbon and hydrogen) reacts with oxygen to produce energy in the form of heat and light. The general equation for a complete combustion reaction involving a hydrocarbon is:
Hydrocarbon + Oxygen → Carbon Dioxide + Water + Energy (heat and light)
For example, the combustion of methane (CH4), which is a simple hydrocarbon, can be represented by the following chemical equation:
CH4 + 2O2 → CO2 + 2H2O + Energy
In this reaction, one molecule of methane reacts with two molecules of oxygen to produce one molecule of carbon dioxide, two molecules of water, and energy.
