Chapter 12, Problem 7E

(a)

Interpretation Introduction

Interpretation:

The solution is given to become colder when ammonium chloride was dissolved in water. Based on the given information given question is to be answered.

Concept introduction: The heat of solution is the sum of enthalpy of solute and enthalpy of hydration. It is calculated by the formula,

  $\Delta H_{\text{soln}}=\Delta H_{\text{solute}}+\Delta H_{\text{Hydration}}$
