Step-by-step explanation:
If an object goes through a chemical reaction but does not change in mass, it typically indicates that the object has undergone a chemical reaction called a "reversible reaction." In a reversible reaction, the reactants combine to form products, but the products can also react to reform the original reactants. As a result, there is no net change in the total mass of the system, even though a chemical transformation is occurring. This concept is a fundamental aspect of chemical equilibrium in reversible reactions.
