Chapter 5, Problem 5.119AP

Interpretation Introduction

Interpretation: The given chemical equation is to be balanced by naming the reactant and product. The standard enthalpy change of the given reaction is to be calculated.

Concept introduction: The standard enthalpy change for a balanced reaction $\left(\Delta H_{\text{balanced rxn}}^{\text{ο}}\right)$ is calculated by the formula,

$\Delta H_{\text{balanced rxn}}^{\text{ο}}={\displaystyle \sum n\times \Delta H_{\text{f}}^{\text{ο}}\left(\text{Products}\right)}-{\displaystyle \sum m\times \Delta H_{\text{f}}^{\text{ο}}\left(\text{Reactants}\right)}$

To determine: The standard enthalpy change of the given reaction and name of reactant and product in balanced reaction.
