Question

Balancing of chemical equations is necessary because atoms are neither_____ nor_____ during a chemical reaction.

• A. created
• B. destroyed

Answer 1

1. Balancing chemical equations is the process of making the number of atoms of each element on both sides of the arrow $(\to )$ in a chemical reaction equal.
2. It is required because all chemical reactions follow the law of conservation of matter.
3. This law states that atoms are neither created nor destroyed.
4. So, balancing at both ends is required.

Hence, balancing chemical equations is necessary because atoms are neither created nor destroyed during a chemical reaction.
