Answer :
The products are carbon dioxide and water (D), since this is what we are left with at the end of the reaction.
Methane is a hydrocarbon, hydrocarbons burning in the presence of oxygen results in a combustion reaction that yields a large amount of energy
balanced equation for the combustion reaction for methane is as follows
CH₄ + 2O₂ --> CO₂ + 2H₂O
the products of the reaction as stated above are
CO₂ and H₂O
answer is
D.carbon dioxide and water
