(1 point)
o It shows that the properties of the elements stay the same after
the reaction.
• It shows that all compounds remain bonded after the reaction.
o It shows that no atoms have been gained or lost during the
reaction.
o It shows that only physical changes follow the Law of conversation of mass

The correct answer is: **It shows that no atoms have been gained or lost during the reaction.**
The Law of Conservation of Mass states that in a closed system, the mass of reactants must equal the mass of products, meaning that the total number of atoms of each element remains constant throughout the reaction. In the given balanced chemical equation, the number of atoms of each element on the reactant side (left) is equal to the number of atoms on the product side (right), indicating that no atoms are lost or gained during the reaction.
