Define nuclear fission. Write the fission reaction of a neutron with uranium isotope `""_(92)U^(235)`.
Write one use of nuclear fission reaction.

Explanation

### Step-by-Step Solution:

1. **Definition of Nuclear Fission:**
Nuclear fission is a process in which a heavy and unstable atomic nucleus splits into two or more smaller nuclei, along with the release of a significant amount of energy. This process typically occurs when the nucleus absorbs a neutron, leading to its instability and subsequent division.

2. **Fission Reaction of Neutron with Uranium Isotope \( _{92}^{235}U \):**
When a neutron collides with the uranium-235 nucleus, the following fission reaction occurs:
