Ethane is a hydrocarbon that can be burned as a fuel. It's chemical formula is C2H6, and it is a colourless compressed liquified gas that is odourless when it is pure. Generally ethane is not completely pure, as it is usually mixed with other hydrocarbons. It is often one of the components of natural gas.[2] Ethane undergoes hydrocarbon combustion, combining with oxygen to form carbon dioxide. The balanced chemical equation for the complete combustion of ethane is:[3]

$2C_2H_6 + 7(O_2)\leftrightarrow 4(CO_2) + 6(H_2O)$

This reaction is a source of primary energy.
