Answer:
The products of these chemical reaction are A. CO2+2H2O+energy
Step-by-step explanation:
In a chemical or biochemical reaction the reactants are placed on the left side and the products are placed on the right hand side with respect to the sign of equilibrium.
From this point of view the products of the given chemical reaction are Carbon dioxide(CO2),water(H2O) and energy.
The chemical reaction states that in presence of oxygen methane gs is converted to carbon dioxide(CO2) and water(H2O) with the liberation of energy.
As a result Methane(CH4) and oxygen(O2) act as reactant whereas CO2,H2O and energy are the products in the mentioned reaction.
