A balanced chemical equation demonstrates the Law of Conservation of Mass if: D. It shows that no atoms have been gained or lost during the reaction.
A chemical equation can be defined as the symbolic representation of a chemical reaction between two or more chemical elements, through the use of chemical symbols and formulas.
A balanced chemical equation is a chemical equation wherein the number of atoms on the reactant (left) side is equal to the number of atoms on the product (right) side.
This ultimately implies that, both the charge on each atom and sum of the masses of the chemical compounds or elements in a chemical equation are properly balanced.
The Law of Conservation of Mass (LOCOM) states that mass is neither created nor destroyed in any chemical reaction.
Hence, a balanced chemical equation requires the same number of atoms on the reactant side and product side of a chemical reaction.
In conclusion, LOCOM is demonstrated by a balanced chemical equation if it shows that no atoms have been gained or lost during the chemical reaction.
