Chapter 19, Problem 19.102CP

Interpretation Introduction

Interpretation:

The amount of energy in kJ/mol which is released during the process.

Concept introduction:

Einstein’s equation
It states that any reaction releases or absorbs energy due to gain or loss in the mass. Energy and mass are equivalent.

$\Delta E=\Delta m{c}^2$

$\Delta E$ is the change in energy in joules

$\Delta m$ is the change in mass in kg
c is the speed of light

Given:

$Th\stackrel{}{\to }Pb+6\alpha +4\beta$
