CH4 + 2O2 → CO2 + 2H2O
Methane + Dioxygen = Carbon Dioxide + Water
The reaction is named as combustion reaction. When this reaction takes place, the result is carbon dioxide (CO2), water (H2O), and a great deal of energy. Burning methane releases only carbon dioxide and water. Since natural gas is mostly methane, the combustion of natural gas releases fewer by-products than other fossil fuels.
