Energy Released in Reaction

APPH12-8B4UXG

In a certain exothermic nuclear reaction, the reactants have a total mass of ${ m }_{ r }$, and the products have a total mass of ${ m }_{ p }$.

Which one of the following is a correct expression for the energy released during this reaction?

A

$$({ m }_{ r }-{ m }_{ p })({ c }^{ 2 })$$

B

$$ ({ m }_{ r }-{ m }_{ p }) / { c }^{ 2 }$$

C

$$ ({ m }_{ r }+{ m }_{ p })({ c }^{ 2 })$$

D

$$({ m }_{ r }+{ m }_{ p })/ { c }^{ 2 }$$
