3. A fission chain reaction. a. A neutron can cause 235U to fission, producing two daughter nuclei (tin and molybdenum) and three more neutrons. These three neutrons can then, in turn, cause three more 235U nuclei to split. One typical reaction is summarized as follows: n+25131Sn + 102Mo +3 n Find the energy released in this process (in MeV), given that MC3SU) 235.0439 u; M(3Sn) 130.9169 u; M(102Mo)-101.9103 u. b.

Consider a fission reaction where a Uranium-235 nucleus absorbs
a neutron and then splits to Strontium, Xenon, and some neutrons.
If the strontium nucleus has a mass number of 89 and the Xenon
nucleus has a mass number of 144, how much energy is released in a
single reaction? Use the attached table for the atomic masses of
the nuclei. Give your answer in MeV and with 4 significant figures.
