What is the main reason why chemical equations must be balanced?
Options
A To avoid formation of unwanted products
B Because atoms must be rearranged randomly
C Because atoms are neither created nor destroyed
Correct Answer
D To ensure molecules are properly synthesized
Correct Answer

Option C is the correct answer.

Detailed Explanation

Balancing chemical equations ensures that the Law of Conservation of Mass is obeyed. This law states that matter cannot be created or destroyed in a chemical reaction, so the number of atoms of each element must be the same on both sides of the equation.

Hint

This fundamental law of chemistry is the basis for balancing equations.
