Chapter 24, Problem 24.109P

(a)

Interpretation Introduction

Interpretation:

Balanced nuclear equation for the given reaction has to be written.

Concept Introduction:

Mass number is the net number of neutrons and protons present in a nucleus.

The elemental symbol of an element: ${}_{\text{Z}}^{\text{A}}\text{X =}{}_{\text{Atomic}\text{number}}^{\text{Mass}\text{number}}\text{X}$

(b)

Interpretation Introduction

Interpretation:

Energy $\left(inkJ\right)$ released for the given reaction has to be determined.

Concept Introduction:

Interpretation:

Energy equivalent of a mass difference of $\text{7}\text{.7}\times {\text{10}}^{-2}\text{ amu}$ has to be calculated $inMeV$.

Concept Introduction:

Nuclear reaction: A nuclear reaction in which a lighter nucleus fuses together into new stable nuclei or a heavier nucleus split into stable daughter nuclei with the release of large amount of energy.

Unit conversion:

  $\begin{array}{c}1\text{ amu = 931}\text{.5}\times {\text{10}}^6\text{ eV = 931}\text{.5 MeV}\\ \\ 1\text{ MeV = }\left({\text{10}}^6\text{ eV}\right)\left(\frac{1.602\times {10}^{-19}\text{ J}}{1\text{ eV}}\right)\end{array}$
