Please help with the solution.

4.3 A. Use the method of Example 6.2 to find the energy released in the reaction 235 U +n -> 140Te + 94 Zr + 2n The masses can be found at: http://periodictable.com/index.html At this link, click on the element in the periodic table and it will take you to a page with the element's isotope data. (To easily convert atomic mass units u to MeV, use Eq. 5.11) B. How much energy is released in the fusion reaction H + 2H -> 'He + n
