Answer: a new substance(s) with the same number of atoms as the initial substance(s) is formed​

Explanation:

Chemical reaction is a reaction in which there is rearrangement of atoms and thus new substance is formed.

According to the law of conservation of mass, mass can neither be created nor be destroyed in  chemical reaction. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
