Chapter 19.2, Problem 19.2P

(a)

Interpretation Introduction

Interpretation:

The electron-dot structure for ${\text{HNO}}_{\text{3}}{\text{ and H}}_{\text{3}}{\text{PO}}_{\text{4}}$, and suggest a reason for the difference in the formulas of these acid have to be drawn.

Concept Introduction:

Lewis structure otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol.  Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.

(b)

Interpretation Introduction

Interpretation:

The given statement has to be explained.
