Part A
Nuclear reactors generate power by harnessing the
energy from nuclear fission. In a fission reaction,
uranium-235 absorbs a neutron, bringing it into a
highly unstable state as uranium-236. This state
almost immediately breaks apart into two smaller
fragments, releasing energy. One typical reaction is
140 Xe +94 Sr + 2,n,
What is the reaction energy Q of this reaction? Use c? = 931.5 MeV/u.
Express your answer in megaelectron volts to three significant figures.

fact, many different fission reactions go on inside a
reactor, but all have similar reaction energies, so it
is reasonable to calculate with just one. The
products of this reaction are unstable and decay
shortly after fission, releasing more energy. In this
problem, you will ignore the extra energy
contributed by these secondary decays.

at a distance of about 5.3 × 10-11 m from the
nucleus, which has a diameter of about
1.0 × 10-15

hydrogen atom were enlarged to the size of a
baseball (diameter = 7.3 cm).
