Which statement provides the best description of the Law of Conservation of Matter?

The total amount of energy in a system remains constant during a chemical reaction.

Atoms are rearranged to form new substances, but the total mass of the system remains unchanged.

In a chemical reaction, the mass of the products is always significantly greater than the mass of the reactants.

Some atoms are converted into energy during a chemical reaction, causing a decrease in total mass.

According to the Law of Conservation of Matter, what happens to the individual atoms involved in any chemical reaction?

They are changed into new types of atoms.

They are simply rearranged into new combinations.

They are destroyed and cease to exist.

They are converted directly into energy.
