उत्तर १
Nuclear Fission :
When a slow neutron strikes `""_92U^235` nucleus, it is absorbed by the nucleus and an isotope `U^236` is formed. But `U^236`, is highly unstable, is immediately broken into two fragments and emits neutrons and energy. This fission can be represented by the following equation
उत्तर २
Nuclear fission:
`""_0^1n + ""_92^235U -> ""_56^144Ba + ""_36^89Kr + 3 ""_0^1n`

Write one balanced equation to show Nuclear fusion
In a nuclear reaction
`"_2^3He + _2^3He -> _2^4He +_1^1H +_1^1H + 12.86 Me V` though the number of nucleons is conserved on both sides of the reaction, yet the energy is released. How? Explain.
Calculate the Q-values of the following fusion reactions :-
(a) `""_1^2H + ""_1^2H → ""_1^3H + ""_1^1H`
(b) `""_1^2H + ""_1^2H → ""_2^3H + n`
(c) `""_1^2H + ""_1^3H → _2^4H + n`.
Atomic masses are `m(""_1^2H) = 2.014102 "u", m(""_1^3H) = 3.016049 "u", m(""_2^3He) = 3.016029 "u", m(""_2^4He) = 4.002603 "u".`
(Use Mass of proton mp = 1.007276 u, Mass of `""_1^1"H"` atom = 1.007825 u, Mass of neutron mn = 1.008665 u, Mass of electron = 0.0005486 u ≈ 511 keV/c2,1 u = 931 MeV/c2.)
