Answer 1

The correct statement that happens during a chemical change but does not happen during a physical change is: Atoms of one or more substances rearrange into a new substance.

In a chemical change, the composition of the substance changes as chemical bonds are broken and formed, resulting in new substances with different properties. In contrast, physical changes involve alterations in the state or appearance of a substance without changing its chemical identity.
