Precise measurements give the following masses: nuclide mass particle mass 239. 94 Pu 239.0522 u on 1.0086649 u He 4.00260 u je 5.4858 x 10 -4 242 96 Cm 242.0588u 5.4858 x 10 Now consider the following nuclear reaction: 239. 242 He 06 Cm + 94 Pu on Oreleased absorbed Is energy released or absorbed by this reaction? o neither released nor absorbed OI need more information to decide. If you said energy was released or absorbed, calculate how much energy is released or absorbed. Give your answer in both kJ/mol and MeV. Be sure each of your answer entries has the correct number of significant digits. Jmol O Mev Note: take particular care to keep enough digits in any intermediate calculation, and use enough digits in any scientific constants you need, since the data with which. you are working are very precise.
