Answer:
a 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. Chemical equations often contain information about the state of the reactants: solid, liquid, gas, or aqueous. In addition, they always adhere to the law of conservation of mass, which holds that matter can change form, but cannot be created or destroyed.
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.
