In the given equation methane(CH4) is reacts with oxygen(O2) to generate water(H2O) and carbon dioxide(CO2).
In the reactant part 2 molecules of hydrogen(H2) are present and 2 molecules of hydrogen are also present in the product part.
1 carbon atom is part of both reactant and products .
But 1 molecule of oxygen(O2) is present in the reactant on the other hand 2 molecules of oxygen are present in the product.
