'(b) The number of atoms of each element remains the same before and after a chemical reaction' is an incorrect statement. It is not necessarily the same in both sides of the reaction.

A balanced chemical reaction does not have the same number of atoms in each element before and after the reaction.
Explanation:
- An adjusted chemical response implies that the number of iotas of each component is rise to on both sides.
- A balanced chemical reaction is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge, same for both the reactants and the products.
- If each side of the equation has the same number of atoms of a given element that is balanced is called a balanced chemical reaction.
