Precise measurements give the following masses: particle mass nuclide mass on 1.0086649 u 2U 238.05079 u 92 -4 5.4858 x 10u 239, U 239.05429 u 5.4858 x 10 u Now consider the following nuclear reaction: 239 + Oreleased O 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. Round each of your answers to 3 significant digits. OkJ/mol 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.
