Chapter 18, Problem 118AE

Interpretation Introduction

Interpretation: The volume of ${\text{N}}_{\text{2}}\text{O}$ gas collected over water at the total pressure of 94.0 kPa, 22°C that is produced from the thermal decomposition of 8.68 g of ${\text{NH}}_{\text{4}}{\text{NO}}_{\text{3}}$ needs to be determined.

  ${\text{NH}}_{\text{4}}{\text{NO}}_{\text{3(s)}}\stackrel{heat}{\to }{\text{N}}_{\text{2}}{\text{O}}_{\text{(g)}}{\text{ + 2 H}}_{\text{2}}{\text{O}}_{\text{(l) }}$

Concept Introduction:

In a chemical reaction the yield of product is determined with the help of limiting reagent. The Limiting reagent is the reactant that is present in limited amount and will determine the amount of product formed.

The mole concept of balance chemical equation is used to determine the yield of product in the chemical reaction.
