Question

Which is the best statement? 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). Both A and C are correct.

Explanation / Answer

In nuclear fission some mass convert into energy called binding energy and the reaction is highly exothermic, so when nuclear fission occur, the nuclei remaining always has a smaller mass.
