प्रश्न
Which of the following statements is correct about the reaction given below:
\[\ce{4Fe(s) + 3O2(g) -> 2Fe2O3(g)}\]
पर्याय
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 \[\ce{Fe2O3}\] can be increased by taking any one of the reactants (iron or oxygen) in excess.
Amount of \[\ce{Fe2O3}\] produced will decrease if the amount of any one of the reactants (iron or oxygen) is taken in excess.
उत्तर
Total mass of iron and oxygen in reactants = total mass of iron and oxygen in product therefore it follows law of conservation of mass.
Explanation:
\[\ce{4Fe + 3O2 -> 2Fe2O3}\] follows law of conservation of mass since mass of reactants is equal to mass of products.
