Which of the following statements is correct about the reaction given below?
1 Total mass of iron and oxygen in reactants = total mass of iron and oxygen on product therefore it follows law of conservation of mass.
2 Total mass of reactants = total massof product; therefore, law of multiple proportions is followed.
3 Amount of can be increased by taking any one of the reactants (iron or oxygen) in excess.
4 Amount of produced will decrease if the amount of any one of the reactants (iron or oxygen) is taken in excess.
Explanation:
Balanced chemical equation obeys law of conservation of mass.

n g of a substance X reacts with m g of substance Y to form p g of substance R and q g of substance S. This reaction can be represented as follow : The relation which can be established in the amounts of the reactants and the products will be
1 n – m = p – q
2 n + m = p + q
3 n = m
4 p = q
Explanation:
n + m = p + q by law of conservation of mass
