The mass of oxygen gas produced should be calculated. Concept Introduction: When sodium peroxide is added to water and oxygen gas is produced as follows: Na 2 O 2 ( s ) + H 2 O ( l ) → NaOH ( a q ) + O 2 ( g ) Balanced chemical reaction is as follows: 2Na 2 O 2 ( s ) + 2 H 2 O ( l ) → 4 NaOH ( a q ) + O 2 ( g ) The mass of oxygen gas produced can be converted from its number of moles and the number of moles produced depends on the number of moles of Na 2 O 2 react in the chemical reaction.

Solutions

Chapter 9, Problem 84AP
Interpretation Introduction

Interpretation:

The mass of oxygen gas produced should be calculated.

Concept Introduction:

When sodium peroxide is added to water and oxygen gas is produced as follows:

Na2O2(s)+H2O(l)NaOH(aq)+O2(g)

Balanced chemical reaction is as follows:

2Na2O2(s)+2H2O(l)4NaOH(aq)+O2(g)

The mass of oxygen gas produced can be converted from its number of moles and the number of moles produced depends on the number of moles of Na2O2 react in the chemical reaction.
