Chapter 10, Problem 10.34QP

Interpretation Introduction

Interpretation: The heat liberated by Magnesium has to be calculated in the units of $\text{kJ}{\text{g}}^{\text{-1}}\text{,}\text{kJ}{\text{mol}}^{\text{-1}}$ .

Concept Introduction:

Heat capacity can be defined as quantity of heat required to raise the temperature of the object by $\text{1°C}$.

The other equation that is used to calculate heat from heat capacity can be given by,

$\text{q=CΔT}$

Where,

$\text{C=}$ Heat capacity of calorimeter

$\text{ΔT=}$ Change in temperature

The unit of heat capacity is $\text{J}{\text{.°C}}^{\text{-1}}$

To calculate: The heat liberated in $\text{kJ}{\text{g}}^{\text{-1}}$
