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