The reaction CH 4 (g)+ 2 O 2 (g)→ CO 2 (g)+ 2 H 2 O (g)is:

This reaction is a combustion reaction because it involves the burning of methane in oxygen. It is a redox reaction because there is a transfer of electrons (carbon is oxidized and oxygen is reduced). It is also exothermic because it releases energy in the form of heat.
