CH₄ + 2O₂ → CO₂ + 2H₂O

This equation represents the following:

* CH₄: Methane, the fuel being burned

* O₂: Oxygen, the oxidizer

* CO₂: Carbon dioxide, a product of combustion

* H₂O: Water, another product of combustion

The coefficients in the equation (1, 2, 1, 2) represent the stoichiometric ratios, meaning the exact amount of each molecule needed for the reaction to occur completely.
