A chemical equation is said to be balanced if number of-

Correct option is A

The correct answer is (a) Atoms are the same on both sides.
· A chemical equation is said to be balanced when the number of atoms of each element is the same on both the reactant and product sides of the equation.
· This follows the law of conservation of mass, which states that mass (and therefore atoms) cannot be created or destroyed in a chemical reaction.
Information Booster:
· Compounds and molecules do not need to be the same on both sides.
· The balancing of electrons is more relevant to redox reactions but is not a general rule for all chemical equations.
