Question

Precise measurements give the following masses: particle mass nuclide mass on 1.0086649 u 239pu 239.0522 u 94 e 5.4858 x 10-4u 2daPu 241.0569 u e 5.4858 x 104 Now consider the following nuclear reaction: 239 94 O released O absorbed Is energy released,or absorbed by this reaction? O neither released nor absorbed O I 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. krmol 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. Suppose a 500. mL flask is filled with 0.20 mol of NO2, 0.10 mol of NO and 0.90 mol of CO2. The following reaction becomes possible 2(g) The equilibrium constant K for this reaction is 7.25 at the temperature of the flask. Calculate the equilibrium molarity of NO. Round your answer to two decimal places.
