Question

For the given series reaction in n step, find out the number of produced neutrons & energy.
​

Answer 1

Answer:

From the given equation we know that mass of Barium is 139g and the mass of Krypton is 94g. Thus, on compairing the masses on the reactant side and the product side we will get 238 -(139 + 94) = 5. Hence, to balance we need 8 neutrons.

Thus, the mass which had to be balanced was 5*1.0087g = -5.0435g or -0.0050435Kg.  

As, the formulae of energy is E=mc^2, given by Eisenstein himself.

Thus, the energy produced by the uranium atom in the above reaction will be E = (-0.0050435 kg)(3.00 × 10^8 m/s)^2 = −1.51 × 10^6 J = −1.51 × 10^3 kJ.
