Question

What must you know about a nuclear reaction to calculate the amount of

energy it will produce?
OA. The sum of the total nuclear mass before and after the reaction
OB. The difference between the total nuclear mass before and after
the reaction
OC. The ratio of total nuclear mass before the reaction to the total
nuclear mass after the reaction
D. The product of the total nuclear mass before and after the
reaction

Answer 1

B. The difference between total nuclear mass before and after the reaction.

This is because you can see how much nuclear matter had actually been used in the reaction by finding the difference between the initial mass and final mass.
