(a) Matter cannot be created and destroyed by a chemical reaction.

Explanation:

(a) Matter cannot be created and destroyed by a chemical reaction. (correct)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.

(b) The reactants are the same substance as the products. (wrong)

You may see in the reaction that we have as reactants zinc and hydrochloric acid which react to form the products, zinc chloride and hydrogen.

(c) The number of molecules in the reactants are equal to the number of molecules in the products. (wrong)

As reactants we have 2 hydrochloric acid (HCl) molecules and as products 1  hydrogen (H₂) molecule. Zn is a metal and ZnCl is a salt.

(d) The atoms on the reactants side are changed into different atoms on the products side. (wrong)

The number and type of atoms entering the chemical reaction are the same with the number and type of atoms leaving the chemical reaction.
