Mass defect and nuclear binding energy — practice question
One possible reaction occurring in the core of a nuclear reactor is represented by the incomplete nuclear equation below
$^{235}_{92}\text{U} + ^{1}_{0}\text{n} \rightarrow ^{139}_{57}\text{La} + ^{95}_{42}\text{Mo} + 2^{1}_{0}\text{n} + \ldots$
(a(i))[1]
State the term used for this kind of nuclear reaction.
(a(ii))[2]
Complete the nuclear equation shown.
(b(i))[2]
The mass defect in the reaction is $0.223\ \text{u}$. Calculate the energy, in J, that corresponds to $0.223\ \text{u}$.
(b(ii))[2]
Suggest two forms that the energy released in this reaction can take.
