Question

Write true or false for the following statement:
Balancing chemical equations is necessary because the law of conservation of matter must hold good during a chemical reaction.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation:

Balancing of a chemical equation:

1. The method by which the number of atoms of each element on both sides of the arrow $(\to )$ in a chemical reaction is made equal is called the balancing of a chemical equation.
2. Balancing of chemical equation is necessary because atoms are neither created nor destroyed during a chemical reaction.
3. Thus, the balancing of chemical equations is based on the law of conservation of matter/mass.

Hence, the statement is true.
