Chapter 20, Problem 20.100QP

Interpretation Introduction

Interpretation: The law of conservation of mass should be satisfied or not for the given condition should be explain.

Concept Introduction:

• On accordance with law of conservation of mass, for any chemical reaction, total masses of reactants and products must be equal.

To calculate the nuclear binding energy:

• Firstly determine the difference between the mass of the nucleus and the mass of all the protons and neutrons, which yields the mass defect.
• Next, we must apply Einstein mass – energy relationship.
• The nuclear binding energy per nucleon is given by the following equation
• Nuclear binding energy per nucleus= $\frac{\text{nuclear binding energy}}{\text{number of nucleons}}$
• Einstein mass energy relationship [ $\text{ΔE}=({\text{ΔM)c}}^{\text{2}}$].

To Explain: The law of conservation of mass really violet in this case.
