Calculate the ratio of the energy released by the complete
fission of 1.0 kg of Uranium-235 to the energy released by burning
1.0 kg of methane, CH4. You can use the fact that one mole of CH4
gives 802 kJ of energy, and recall from your chemistry course that
there are 6.02*1023 atoms per mole.

On neutron-capture induced fission, 235 92U typically splits
into two new “fission product” 92 nuclei with masses in the ratio
1:1.4. These are born with the same proton to neutron ratio as the
original uranium, so they have too many neutrons to be stable at
their mass number and are highly radioactive. Energy is released in
two stages: first an intermediate or prompt release leading to
radioactive fission products in their ground state; and then a much
slower release via...

Why is uranium-235 the only isotope of uranium that can be used
as fuel for a nuclear weapon?
A uranium 235 particle is struck by a neutron creating a
fission event. The uranium splits into the following atoms and
particles: A Barium 141 atom, a Krypton 92 atom, and 3 neutrons.
Use this information and your knowledge of electrostatics,
fundamental forces, and the conservation of energy to explain
(conceptually) how this produces energy.
After a fission event occurs the Barium...

Given that the average number of fast neutrons emitted following
the thermal-neutron induced fission of 235U is 2.42 per fission
event; use the following data to calculate the mean number of
fission neutrons produced per initial thermal neutron in a large
volume sample of
(a) pure 235U (b) natural uranium 238U, and (c) uranium enriched to
3% in the 235U isotope.
Note: The microscopic absorption cross section for 235U is 694
barns. The cross section for 238U is 2.71 barns....

1a Describe how thermal energy is obtained by
fission, specifically when a U=235 atom is hit by a slow-motion
neutron (less than 0.9 MeV). When one states that 200 MeV of energy
are released by a fission event, what is the form of this
energy?
1b. The energy released by fission is by the
change in mass and Einstein’s equation (E=Δmc2). If the
mass of one uranium 235 atom is 235.042924 amu and the mass of
fission products is 234.92754...

a.) A neutron can cause 235U to fission, producing
two daughter nuclei (tin and molybdenum) and three more
neutrons. These three neutrons can then, in turn, cause three more
235U nuclei to split. One typical reaction is summarized
as follows:
n + 235U ® 131Sn + 102Mo + 3
1n
Find the energy released in this process (in MeV), given that
M(235U)=235.0439 u; M(131Sn)=130.9169 u;
M(102Mo)=101.9103 u.
b.)Lise Meitner’s work in 1938 predicted that the fission of
235U would produce...
