The explosive in a hydrogen bomb is a mixture of

{ }_1 {H}^2,{ }_1 {H}^3

and

{ }_3 {Li}^6

in some condensed form. The chain reaction is given by

\begin{aligned} & { }_3 {Li}^6+{ }_0 {n}^1 \longrightarrow{ }_2 {He}^4+{ }_1 {H}^3 \\ & { }_1 {H}^2+{ }_1 {H}^3 \longrightarrow{ }_2 {He}^4+{ }_0 {n}^1 \end{aligned}

During the explosion the energy released is approximately
[Given :

{M}({Li})=6.01690\, {amu}, {M}\left({ }_1 {H}^2\right)=2.01471\, {amu}

{M}\left({ }_2 {He}^4\right)=4.00388 \,{amu}

, and

1\, {amu}=931.5 \,{MeV}

]

View answer and explanation

Correct option: A

22.22 \,{MeV}

Option A (

22.22 \,{MeV}

) is correct because it is the approximate energy released during the fusion reactions, calculated from the mass defect.
