Detailed explanation-1: -The combustion of methane or octane is exothermic; it releases energy. CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants.

Detailed explanation-2: -1 C atom, 4 H atoms & 2 O atoms.

Detailed explanation-3: -In the given reaction, both CH4 C H 4 and O2 are present at the left-hand side of the arrow. Hence, both CH4 C H 4 and O2 are reactants.

Detailed explanation-4: -This is combustion reaction and also it is redox reaction because the oxidation number of O2 is molecule are 0. But in water its oxidation number is−2.so reduction in methene the oxidation number ofH=−1 and in H2O its oxidation number of hydrogen is +1.
