Answer 1

Answer: The equation that represents a fission reaction is:

92 U235 + 0 n1 → 94 Pu239 + -1 e0

In this equation, a uranium-235 nucleus (92 U235) is bombarded with a neutron (0 n1), which results in the formation of a plutonium-239 nucleus (94 Pu239) and the release of an electron (-1 e0).

Fission is a nuclear reaction in which a heavy nucleus, such as uranium-235, is split into two or more smaller nuclei, along with the release of energy and additional particles, such as neutrons. This reaction is commonly used in nuclear power plants and atomic bombs.

Please note that fission reactions can involve different elements and isotopes, but the key aspect is the splitting of a heavy nucleus into smaller fragments.
