Chapter 14, Problem 8P

(a)

To determine

Q value for the reaction ${}_2^4\text{He}\text{+}{}_4^9\text{Be}\to {}_6^{12}\text{C}\text{+}{}_0^1\text{n}$.

(b)

To determine

Q value for the reaction ${}_1^2\text{H}\text{+}{}_1^2\text{H}\to {}_2^3\text{He}\text{+}{}_0^1\text{n}$ and decide whether the reaction is exothermic or endothermic.
