Answer 3

[AI-generated answer — Explain Bot]

The correct statement that best explains why mass is not conserved in a nuclear change is "Some of the matter is converted to energy." When a nuclear change occurs, such as in nuclear fission or fusion, the nucleus of an atom undergoes a transformation. During this process, a small amount of matter is converted into a significant amount of energy according to Einstein's famous equation, E=mc². This conversion of matter into energy results in a decrease in the total mass of the system. Therefore, in a nuclear change, mass is not conserved because some of the matter is converted to energy.
