Chapter 13, Problem 113AE

Interpretation Introduction

Interpretation: The Lewis structure of ${\text{CO}}_{{}_{\text{3}}}^{\text{2-}}{\text{,HCO}}_{{}_{\text{3}}}^{\text{-}}{\text{,H}}_{\text{2}}{\text{CO}}_{{}_{\text{3}}}^{}$ needs to be determined and and the value of $\text{ΔH}$ for the given reaction needs to be determined.

  ${\text{H}}_{\text{2}}{\text{CO}}_{{}_{\text{3}}}^{}\stackrel{}{\to }{\text{CO}}_{{}_{\text{2}}}^{}{\text{+H}}_{\text{2}}\text{O}$

Concept Introduction:

Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Lewis dot structure is also known as Lewis dot formula or electron dot structure.

The bond energy of a chemical bond can be defined as the energy required to break that chemical bond. The bond energy that is needed to break the bonds in reactant molecule and the energy released to form chemical bonds in product can be used to calculate the $\Delta \text{H}$ of the chemical reaction.

  $\Delta \text{H=}\sum {\text{BE}}_{\text{reactant }}\text{- }\sum {\text{BE}}_{\text{product }}$
