_92^238 A →_90^234 B+_2^4 D+Q In the given nuclear reaction, the approximate amount of energy released will be: [Given, mass of _92^238 A=238.05079 ×…
$${ }_{92}^{238} A \rightarrow{ }_{90}^{234} B+{ }_2^4 D+Q
$$
In the given nuclear reaction, the approximate amount of energy released will be:
[Given, mass of $\displaystyle { }_{92}^{238} A=238.05079 \times 931.5 \mathrm{MeV} / \mathrm{c}^2$,
$$\begin{aligned}
& \text { mass of } { }_{90}^{234} B=234.04363 \times 931.5 \mathrm{MeV} / \mathrm{c}^2, \\
& \text { mass of } \left.{ }_2^4 D=4.00260 \times 931.5 \mathrm{MeV} / \mathrm{c}^2\right]
\end{aligned}
$$
