Answer: - C. The number of atoms in the product is the same number of atoms in the reactant.

Explanations: - Chemical equations obey law of mass conservation of matter. According to this law, " Matter is neither created nor destroyed.

So, to obey this law, chemical reactions must be balanced. A balanced chemical equation means it has equal number of atoms of each element on both sides and so the correct statement is C.

The given balanced equation has two potassium, two chlorine and six oxygen atoms on each side and so it is balanced.
