What is a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy?

Excretion
Fallout
Fission
Fatty acid

The correct answer is: Fission

The correct answer is fission, which refers to a type of nuclear reaction where a large, unstable nucleus splits into smaller nuclei, along with the release of a significant amount of energy. This process occurs when the nucleus absorbs a neutron, becomes unstable, and undergoes a chain reaction that can release additional neutrons, leading to further fission events and more energy release. Fission is the principle behind nuclear power and atomic bombs, demonstrating its importance in both energy generation and weaponry. The other terms do not relate to this specific nuclear process. Excretion refers to the removal of waste from the body, fallout pertains to the residual radioactive particles following a nuclear explosion, and fatty acids are organic compounds important in biology and nutrition, unrelated to nuclear reactions.
