Chapter 22, Problem 28E

Interpretation Introduction

(a)

Interpretation:

The decomposition reaction that yields the most ${\text{O}}_{\text{2}}\left(\text{g}\right)$ needs to be determined from the given options.

Concept introduction:

At first, write balanced chemical equation for each reaction. Then compare moles of each reaction and find the reaction where highest moles of oxygen formed.

Interpretation Introduction

(b)

Interpretation:

The decomposition that yields the most ${\text{O}}_{\text{2}}\left(\text{g}\right)$ needs to be determined from the given options.

Concept introduction:

First, write balanced chemical equation for each reaction. Then calculate oxygen formed per gram of reactant.

Mass can be calculated from number of moles and molar mass as follows:

$m=n\times M$

Here, n is number of moles and M is molar mass.
