Law of conservation in nuclear reactions, Physics

Assignment Help:

(i) Conservation of charge number and mass number : In the given nuclear reaction

473_22.png

Mass number (A) → Before the reaction                After the reaction

                                4 +14 = 18                            17 + 1 = 18

       Charge number (Z)→ 2 + 7 = 9                       8 + 1 = 9

(ii)  Conservation of momentum: Linear momentum/angular momentum of particles before the reaction is equivalent to the linear/angular momentum of the particles after the reaction. That is Σp = 0

(iii) Conservation of energy: Total energy before the reaction is equivalent to total energy after the reaction. Term Q is attached to balance the total energy of the reaction.
