(a)[3]
State the meanings of nuclear fusion and nuclear fission.
(b(i))[1]
A nuclear reaction that could, in the future, be used to generate electrical energy is $^{2}_{1}\text{H} + {}^{3}_{1}\text{H} \rightarrow {}^{4}_{2}\text{He} + x$. Name the particle $x$.
(b(ii).1)[1]
Fig. 12.1 gives data for the binding energy per nucleon $E_B$ of several nuclei. State the binding energy per nucleon of $x$.
(b(ii).2)[3]
Calculate the energy change produced in this reaction.
(b(iii))[1]
Use your answer to part (ii) part 2 to find the energy released when $2.0\,\text{g}$ of deuterium $({}^{2}_{1}\text{H})$ reacts with $3.0\,\text{g}$ of tritium $({}^{3}_{1}\text{H})$.
