Which of the following statements is correct about the reaction
given below ? 4Fe(s) + 3O₂ (g) ¾¾®2Fe₂O₃(g)
(a) Total mass of iron and oxygen in reactants = total mass of iron and
and oxygen in product therefore, it follows law of conservation of mass.
(b) Total mass of reactants = total mass of product; therefore, law of
multiple proportions is followed.
(c) Amount of Fe₂O₃ can be increased by reducing the amount of any
one of the reactants (iron or oxygen).
(d) Amount of Fe₂O₃ produced will decrease if the amount of any one
of the reactants (iron or oxygen) is taken in excess.
