Expert Solution
Check Mark

Answer to Problem 20P

The number of neutrons produced is 5

Explanation of Solution

Given:

Consider the reaction.

  92235U+n51133Sb+4198Nb+?n

Calculation:

Calculate the mass number from both the sides.

  235+1=133+98+??=5

Thus, the number of neutrons produced is 5.

(b)

To determine

The released energy.

Answer to Problem 20P

The released energy.is 171.1 MeV

Explanation of Solution

Given:

The atomic mass of Sb and Nb isotopes are 132.915250u and 97.910328u.

Formula used:

The reaction is,

  92235U+n51133Sb+4198Nb+5n

Thus,

  Q=m92235Uc2+mnc2m51133Sbc2m4198Nbc25mnc2

Calculation:

Substitute the values in the above equation.

  Q=m92235Uc2+mnc2m51133Sbc2m4198Nbc25mnc2=235.04392u+1.00865u132.9152u97.9103u5(1.008665)(93.5)=171.1 MeV

Thus, the released energy.is 171.1 MeV.
