Answer:
chemical equation is the representation of total composition change related to the chemical reaction. It represents how reactants react to give a completely new product.
This means that the mass of a closed system of substances will remain constant, regardless of the processes acting inside the system. In other words, for any chemical equation in a closed system, the mass of the reactants must equal the mass of the products.
Therefore, there must be the same number of atoms of each element on each side of a chemical equation. A properly balanced chemical equation shows this.
So Assertion and reason are correct but the reason is not the correct explanation for the assertion.
