Answer
Both A and R are true but R is not the correct explanation of A.
Explanation — In a chemical reaction, the total mass of the substances on either side of the equation is the same, this is referred to be as law of conservation of mass. Hence, the assertion (A) is true.
In a chemical reaction the products are formed by the rearrangement of atoms or elements in the reactants. Hence, the reason (R) is true but reason (R) is not the correct explanation for assertion (A).
