Which of the following statements is correct about the reaction given

1.	Which of the following statements is correct about the reaction given below ? 4 Fe_((s)) +3O_(2(g)) rarr 2Fe_(2)O_(3(g))
Answer» Total mass of iron and OXYGEN in reactants `=` total mass of iron and oxygen in product THEREFORE it FOLLOWS law of conservation of mass. Total mass of reactants `=` total mass of product, therefore, law of multiple proportions is FOLLOWED. Amount of `Fe_(2)O_(3)` can be increased by TAKING any one of the reactants ( iron or oxygen) in excess. Amount of `Fe_(2)O_(3)` will decrease if the amount ofany one of the reactants ( iron or oxygen ) is taken in excess. Solution :According to the law of conservation of mass, The total mass of products `=` Total mass of reactants The Amount of `Fe_(2)O_(3)` is decided by limiting reagent.
