Which equation represents a fission reaction?
14n+h—150
o se ut n— 1 cs + s rb +2n
o be + he — c +ón
28 np — 23 pute
mark this and return

Option B is correct: 235 92U + 1 0n→ 140 55Cs + 94 37Rb + 2 (1 0n)

Explanation:

During nuclear fission, nucleus of an atom splits into smaller parts. The fission process produces free neutrons and photons, and releases a large amount of energy.

In these four reactions, only B option satisfied the conditions of a nuclear fission reaction. Here is more detail

B. 235 92U + 1 0n → 140 55Cs + 94 37Rb + 2 (1 0n)

235 92U atoms split into 140 55Cs and 94 37Rb smaller parts with the help of neutron (energy).

The other three reactions are the example of nuclear transmutation reactions.

A. 14 7N + 1 1H → 15 8O

C. 9 4Be + 4 2He → 12 6C + 1 0n

D. 239 93Np + 239 94Pu + 0 -1e
