Write a balanced nuclear reaction for the neutroninduced fis

Write a balanced nuclear reaction for the neutron-induced fission of U-235 to produce Te-137 and Zr-97. How many neutrons are produced in the reaction.

Referring to the reaction written above, calculate the energy produced per atom of U-235. Report your answer in units of eV (electron volts).

Some useful conversions: 1 eV = 1.602 × 10^−19 J, 1 u = 1.661 × 10^−27 kg.

Some useful masses: neutron = 1.00866 u, U-235 = 235.04393 u, Te-137 = 136.92532 u, Zr-97 = 96.91095 u.

Speed of light (c): 2.998 × 10⁸ m/s

Solution

U235 + 1n-----> Te-137 + Zr 97 + 2n1 ,

so 2 neutrons is produced

E = delta m x 931.5 MeV

= ( 235.04393-136.92532-96.91095-1.00866) = 0.199 amu ,

E = (0.199 x931.5) = 185.37 MeV

= 1.8537 x10^ 8 eV
