Explanation:
Detailed explanation-1: -To balance the hydrogen atoms, put a 2 in front of H2O: CH4 + O2 CO2 + 2H2O. The oxygen atoms can be balanced by putting a 2 in front of the O2 on the left: CH4 + 2O2 CO2 + 2H2O. The equation is now balanced.
Detailed explanation-2: -The complete and balanced chemical equation of the combustion reaction of Methane is written as: CH 4 ( g ) + 2 O 2 ( g ) → CO 2 ( g ) + 2 H 2 O ( l ) + Heat ( Methane ) ( Oxygen ) ( Carbon ( Water ) dioxide )
Detailed explanation-3: -CH 4 ( g ) Methane + 2 O 2 ( g ) Oxygen gas → CO 2 ( g ) Carbon dioxide + 2 H 2 O ( g ) Water vapours.
