If each fission of a 235nucleons 92protonsU nucleus releases about 2.0e2 MeV of energy, determine the energy (in joules) released by the complete fissioning of 0.9 gram of 235nucleons 92protonsU.

Solution Preview

Energy per fission = 200 MeV = 200 * 1.6022*e-13 Joules

Solution Summary

The solution uses simple, easy-to-understand equations to find the answer to the question posed about fission reaction emissions energy.

When 1.0 kg of coal is burned, about 3.0e7 J of energy is released. If the energy released per 23592U fission is 2.0e2 MeV, how many kilograms of coal must be burned to produce the same energy as 1.0 kg of 235nucleons 92protons U?

1. In a particular neutron-induced fission of 235U, 4 prompt neutrons are produced and one fission fragment is 121Ag. (a) What is the other fission fragment? (b) How much energy is liberated promptly (i.e., before the fission fragments begin to decay)? (c) If the total initial kinetic energy of the fission fragments is 150 MeV,

Consider a nuclear power plant that produces 1000 MW of power and has a conversion efficiency fo 30% (that is, for each unit of fuel energy used, the plant produces 0.3 unit of electrical energy). Assuming continuous operation, determine the amount of nuclear fuel consumed by this plant per year. Please show steps and explain. T

1a.) You have 16 electrons, 16 protons, and 16 neutrons. You can combine them to make 8 Helium (He-4) atoms, 4 beryllium atoms (Be-8), 2 oxygen atoms (O-16), or one sulfur atom (S-32). What will you do to make the most stable product?

When some large nuclear plants run at full capacity, they produce about 1900 MW of electrical power. At this rate, what mass of 235U (kg) would it consume per year if the efficiency of converting nuclear energy to electricity is 33%? How many metric tons of coal would be required to supply the same amount of electricity?
Hint

Question #1
When HNO3 is added to HCN(aq), the CN^- concentration is:
(a) increased (b) decreased (c) not changed
Question # 2
For each of the following processes, state whether nuclear fission, nuclear fusion, or neither fission nor fusion is occurring:

The most famous equation in all of the natural sciences is probably:
E = mc^2
Derived by Albert Einstein at the beginning of the 20th century it summarizes the equivalence of energy (E) and mass (M) . That c^2 is so large (c^2 is the speed of light of light (3.0 x 10^8 m/s) squared, 9.0 x 10^16 m^2/s^2
