Question 1

If more than one neutron from each fission event causes another fission event, the fission situation is described as

◦ critical
◦ subcritical
◦ supercritical
◦ moderated
◦ None of these are correct.

Question 2

If one mole of oxygen-16 were formed from protons and neutrons, 0.1366 g of mass would be lost. What can best account for this loss?

◦ When fission occurs, the nuclei remaining always has a smaller mass.
◦ Converting from the atomic scale (in amu's) to the macroscopic scale (in grams) can often cause minor errors to occur.
◦ The process was so exothermic, the system lost energy, which meant that it also lost mass.
◦ This is impossible because of the Law of Conservation of Matter (so mass must be conserved).
◦ At least two of these are correct.
