Answer #1

Oxidation

CH4 +2 O2 -------> CO2 + 2 H2O

It is a combustion reaction , an oxidation.

Any reaction which constitutes oxygen as one of the ingredients, is known as oxidation reaction. Now, combustion is a process in which chemical substances burn in the presence of oxygen and this process can only occur in presence of oxygen.

In a combustion reaction oxygen is combined with the fuel source usually carbon and hydrogen based resulting in carbon dioxide and water and so this is an oxidation reaction.
