A thermal neutron strikes U_(92)^(235) nucleus to produce fission. The nuclear reaction is as given below : n_(0)^(1) + U_(92)^(235) to Ba_(56)^(141) + Kr_(36)^(92) +3n_(0)^(1) + E Calculate the energy released in MeV. Hence calculate the total energy released in the fission of 1 Kg of U_(92)^(235) . Given mass of U_(92)^(235) = 235.043933 amu Mass of neutron n_(0)^(1) =1.008665 amu Mass of Ba_(56)^(141)=140.917700 amu Mass of Kr_(36)^(92)=91.895400 amu

Consider the fission of ""_(92)^(238)U by fast neutrons. In one fission event, no neutrons are emitted and the final end products, after the beta decay of the primary fragments, are ""_(58)^(140)Ce and ""_(44)^(99)Ru . Calculate Q for this fission process. The relevant atomic and particle masses are m(""_(92)^(238)U) =238.05079 u m( ""_(58)^(140)Ce ) =139.90543 u m(""_(44)^(99)Ru ) = 98.90594 u
