Question

A balanced chemical equation is in accordance with the law of conservation of masses.
A.True
B.False

Answer 1

A balanced chemical reaction is a reaction which has equal numbers of atoms of each element on both sides of an equation. We know that the law of conservation of mass states that matter can neither be created nor destroyed.

Complete answer:
Chemicals generally combine in fixed ratios in chemical reactions to form a chemical compound. Since, we know that matter can neither be created nor destroyed, nor can any element transfuse into another during a chemical reaction, hence the amount of each element must be the same before and after the reaction. In other words, the number of atoms of any element in the reactants will always be equal to the number of atoms of that element in the products formed.
The law of conservation of mass implies that the mass must always remain fixed through a chemical reaction. Since in a balanced equation, the amounts and masses of all elements and compounds are equal on both sides of the reaction, it also implies that the mass is conserved.
Thus, we can say that a balanced chemical equation is in accordance with the law of conservation of mass.

The given statement is true.
Note:
Stoichiometry of a substance is based upon the very basic laws of chemistry that help us in the better understanding of the concept, namely, the law of conservation of mass, the law of reciprocal proportions, the law of definite proportions (also known as the law of constant composition) and the law of multiple proportions .
