What does it mean for a
chemical equation to be balanced?

Answer 1

Answer: Matter cannot be created or destroyed in chemical reactions.

Explanation: This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.
