3. This diagram shows a chain reaction where a single neutron causes a U-235 nucleus to split and emit 2 more neutrons, and so on. n 235U 92 For each U-235 fission about 200 MeV of energy is emitted in a time of about 1 x 10+ s in an uncontrolled reaction. In a small nuclear bomb this chain reaction occurred for about 0.005 s. At the end of this time the total amount of energy released would have been about: A. 1 x 10-9 J B. 36 J C. 1 x 103 J D. 36 kJ
