The control of fire

The chemical equation resulting from the butane gas combustion is C4H10 + 132O2 è 4CO2 + 5H2O The Combustion is an exothermic chemical reaction between a substance (fuel) and a gas (combustion), usually oxygen, creating, in this particular case, the formation of carbon dioxide and water.
