Chapter 22, Problem 61E

Interpretation Introduction

(a)

Interpretation:

The chemical equation for the equilibrium developed between nitrogen dioxide and dinitrogen tetroxide in the gaseous state should be determined.

Concept introduction:

A chemical equation is the representation of a chemical reaction with the complete information of reactant and product molecules. Here both types of molecules must be written as their chemical symbols separated by the single headed arrow. If the reaction is at the equilibrium position, it must be an equilibrium sign ( $\rightleftharpoons$ ) between reactant and product molecules.

All molecules must be written with their physical state as sub script such as (s) for solid, (l) for liquid, (g) for gas and (aq) for aqueous. A balance chemical equation is the chemical equation in which all the atoms at both sides of the equation are same.

Interpretation Introduction

(b)

Interpretation:

The chemical equation for the reduction of nitrous acid by ${\text{N}}_{\text{2}}{\text{H}}_{\text{5}}{}^{\text{+}}$ resulting in hydrazoic acid, further reduced by hydrazoic acid resulting in the formation of dinitrogen monoxide and nitrogen should be determined.
