Question 44 of 75 in this shift, Physics question 19 of 25, Section A.

Match the LIST-I with LIST-II LIST-I A.

^{1}_{0}\mathrm{n} + {}^{235}_{92}\mathrm{U} \rightarrow {}^{140}_{54}\mathrm{Xe} + {}^{94}_{38}\mathrm{Sr} + 2\,{}^{1}_{0}\mathrm{n}

2\mathrm{H_2} + \mathrm{O_2} \rightarrow 2\mathrm{H_2O}

^{2}_{1}\mathrm{H} + {}^{2}_{1}\mathrm{H} \rightarrow {}^{3}_{2}\mathrm{He} + {}^{1}_{0}\mathrm{n}

^{1}_{1}\mathrm{H} + {}^{3}_{1}\mathrm{H} \rightarrow {}^{2}_{1}\mathrm{H} + {}^{2}_{1}\mathrm{H}
