Which of the following statements is correct about the reaction given below:- `4Fe(s)+3O_(2)(g)rarr2Fe_(2)O_(3)(g)`A. Total mass of iron and oxygen in reactants = total mass of iron and oxygen in product, therefore, it follows law of conservation of mass.B. Total mass of reactant = total mass of product, therefore, law of multiple proportions is followed.C. Amount of `Fe_2O_3` can be increased by taking any one of the reactants (iron or oxygen ) in axcess.D. Amount of `Fe_2O_3` produced will decreased if the amount of any one of the reactants (iron or oxygen ) is taken in excess.
