**Nuclear Reaction Process Identification** **Question:** The following reaction represents what nuclear process? \[ \frac{235}{92}\text{U} + \frac{1}{0}\text{n} \rightarrow \frac{139}{56}\text{Ba} + \frac{94}{36}\text{Kr} + 3 \frac{1}{0}\text{n} \] **Options:** - ○ Nuclear fission - ○ Nuclear fusion - ○ Electron capture - ○ Alpha decay - ○ Beta emission **Explanation:** The equation represents the nuclear reaction involving Uranium-235 (\( \frac{235}{92}\text{U} \)) capturing a neutron (\( \frac{1}{0}\text{n} \)) and splitting into Barium-139 (\( \frac{139}{56}\text{Ba} \)) and Krypton-94 (\( \frac{94}{36}\text{Kr} \)), releasing additional neutrons. **Correct Answer:** - ○ Nuclear fission **Details:** In this reaction, Uranium-235 absorbs a neutron, becomes unstable, and splits into two smaller nuclei (Barium-139 and Krypton-94) along with the release of three more neutrons. This is a classic example of nuclear fission, where a heavy nucleus splits into smaller nuclei with the release of a large amount of energy.
