Chapter 8, Problem 8.66SP

Interpretation Introduction

Interpretation:

Heat released in kilojoules in reaction of $5.00\text{ g}$ of Aluminum with Chlorine has to be calculated.

Concept Introduction:

Enthalpy corresponds to heat content of the system and it is represented by ‘H’ and it is the sum of internal energy ‘E’ and product of volume and pressure,

$H=E+PV$

Change in enthalpy is represented by $\Delta H.$  Heat released or absorbed during a reaction is calculated by,

$q=n\times \Delta H$

Where,

$\begin{array}{l}q=heat\text{ released or absorbed}\\ \text{n}\text{= no}\text{.of moles of the substance that absorbs or releases heat}\\ \Delta H=enthalpy\text{ change}\end{array}$
