From the following equations, pick out the possible nuclear reactions |
${ }_6 C^{13}+{ }_1 H^1 \rightarrow{ }_6 C^{14}+4.3 \mathrm{MeV}$ ${ }_6 C^{12}+{ }_1 H^1 \rightarrow{ }_7 N^{13}+2 \mathrm{MeV}$ ${ }_7 \mathrm{~N}^{14}+{ }_1 \mathrm{H}^1 \rightarrow{ }_8 \mathrm{O}^{16}+7.3 \mathrm{MeV}$ ${ }_{92} U^{235}+{ }_0 n^1 \rightarrow{ }_{54} X^{140}+{ }_{38} S i^{94}+2{ }_0 n^1+\gamma+200 \mathrm{MeV}$ |
${ }_6 C^{12}+{ }_1 H^1 \rightarrow{ }_7 N^{13}+2 \mathrm{MeV}$ |
Only those nuclear reactions are possible in which the sum of mass number of all the reactants is equal to sum of mass number of all the products formed as well as sum of atomic number of all the reactants is equal to sum of atomic number of all the products formed. Hence reactions shown in options B and C satisfy both the above conditions simultaneously, thus these are the possible nuclear reactions. In option A, the condition for atomic number is not satisfied whereas option D does not satisfied the mass number condition. |
