oart A and B please
ission Reactions In a nuclear fission reaction a heavy nucleus divides to form smaller nuclei and one or more neutrons. Many nuclei can undergo fission, but the fission reactions of uranium-235 and plutonium-239 are the principal ones that generate energy in nuclear power plants. This problem deals with balancing the fission reaction of the uranium-235 isotope as it undergoes bombardment from a neutron 14 of 36 > Review Constants 1 Periodic Table When a U...

Suppose that in a nuclear fission event, a U-235 nucleus splits into four new particles. Two of them are the nuclei Kr-90 and Ba-143 and two of them are neutrons (see equation below). Using masses available online or in a chart of nuclides, determine the kinetic energy released in the fission event.^235U rightarrow^90 Kr +^143Ba + 2n + KE

Review Constants | Periodic Tat When a 99 U nucleus is bombarded by neutrons (n) it undergoes a fission feaction, resulting in the formation of two new nuclei and neutrons. The following equation is an example of one such fission process: U + n-Ba + Kr + 3on Enter the isotope symbol for the barium (Ba) nucleus in this reaction. Express your answer as an isotope.
