Question

(A) According to the law of conservation of mass,the total mass of the reactants must equal the total mass of the products in a balanced chemical equa

Vedclass · Accepted Answer

Total mass of iron and oxygen used in reaction $=$ total mass of ferric oxide in product; therefore,it follows law of conservation of mass.

Vedclass · Answer

(A) According to the law of conservation of mass,the total mass of the reactants must equal the total mass of the products in a balanced chemical equation.In the reaction $4Fe_{(s)} + 3O_{2_{(g)}} 	o 2Fe_{2}O_{3_{(s)}}$,the mass of $4$ moles of $Fe$ and $3$ moles of $O_{2}$ equals the mass of $2$ moles of $Fe_{2}O_{3}$.Therefore,statement $A$ is correct as it correctly identifies that the reaction follows the law of conservation of mass.Statement $B$ is incorrect because the law of multiple proportions applies to two elements forming more than one compound,not to a single balanced reaction.Statements $C$ and $D$ are incorrect because the amount of product is determined by the limiting reagent,not by simply adding excess of one reactant.

Which of the following statements is correct about the given reaction?
$4Fe_{(s)} + 3O_{2_{(g)}} \to 2Fe_{2}O_{3_{(s)}}$
