Concept explainers
(a)
Interpretation:
The balanced chemical equation for the decay of U-235 due to neutrons bombardment needs to be determined.
Concept introduction:
A
(b)
Interpretation:
The value of change in energy for fission of 1 g of U-235 needs to be determined.
Concept introduction:
The mass defect for any nuclear reaction is the change in masses of the species involved in the process.
For a general nuclear reaction as follows:
A→B+C
The mass defect can be calculated as follows:
mB+mC−mA
Here, m is
From the mass defect, the change in energy can be calculated as follows:
ΔE=Δmc2
Here, Δm is change in mass and c is
(c)
Interpretation:
The mass of TNT needed to produce the energy same as produced from 1 mg of U-235 needs to be determined.
Concept introduction:
The mass defect for any nuclear reaction is the change in masses of the species involved in the process.
For a general nuclear reaction as follows:
A→B+C
The mass defect can be calculated as follows:
mB+mC−mA
Here, m is atomic mass of A, B and C atoms.
From the mass defect, the change in energy can be calculated as follows:
ΔE=Δmc2
Here, Δm is change in mass and c is speed of light. If the value is negative, the energy is released, if it is positive the energy is required for the reaction.
