Question

. Which of the following statement is correct about the
reaction given below?
4Fe(s)+30 (g) -- 2Fe2O3(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 reactants = total mass of product,
therefore, law of multiple proportions is followed
(c) Amount of Fe,O, can be increased by taking any one
of the reactants (iron or oxygen) in excess
(d) Amount of Fe,0, produced will decrease if the amount
of
any one of the reactants (iron or oxygen) is taken in
excess​
