It sodium peroxide is added to water, elemental oxygen gas is generated:

:math> Na 2 O 2 ( s ) + H 2 O ( l ) NaOH ( a q ) + O 2 ( g )

ppose 3.25 g of sodium peroxide is added to a large excess of water. What mass of oxygen gas will be produced?

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.

Explanation

From the above balanced chemical reaction, 2 moles of Na2O2 on reaction with excess of water gives 1 mol of O2. Here, water is in excess thus, Na2O2 will be the limiting reactant.

Thus, 1 mol of Na2O2 gives 0.5 mol of O2. The mass of Na2O2 is given 3.25 g, number of moles of Na2O2 can be calculated as follows:

n=mM

Here, m is mass and M is molar mass.

Molar mass of Na2O2 is 77
