Nuclear Fission and Nuclear Fusion — Quiz

Question 2 • Chemistry

Which equation represents a fission reaction?

Answer

A

93 to the 239th power Np rightarrow 94 to the 239th power Pu plus negative 1 to the 0 power n

B

7 to the 14th power cap n plus 1 to the 1th power cap h rightarrow 8 to the 15th power cap o

C

92 to the 235th power cap u plus 0 to the 1th power n rightarrow 55 to the 140th power Cs plus 37 to the 94th power Rb plus 2 sub 0 to the 1th power n

D

4 to the 9th power Be plus 2 to the 4th power He rightarrow 6 to the 12th power cap c plus 0 to the 1th power n

Explanation

Fission occurs when a heavy nucleus splits into smaller nuclei, often after absorbing a neutron. In choice C, uranium-235 absorbs a neutron and splits into cesium-140 and rubidium-94, releasing two more neutrons. The other choices show beta decay or nuclear fusion rather than fission.
