Question:

Write balanced equations for reactions between

(a) Na2O2and water

(b) KO2 and water

(c) Na2O and CO2

Solution:

(a) The balanced chemical equation for the reaction between Na2O2 and water is:

$2 \mathrm{Na}_{2} \mathrm{O}_{2(s)}+2 \mathrm{H}_{2} \mathrm{O}_{(i)} \longrightarrow 4 \mathrm{NaOH}_{(a q)}+\mathrm{O}_{2(a q)}$

(b) The balanced chemical equation for the reaction between KOand water is:

$2 \mathrm{KO}_{2(s)}+2 \mathrm{H}_{2} \mathrm{O}_{(i)} \longrightarrow 2 \mathrm{KOH}_{(a q)}+\mathrm{H}_{2} \mathrm{O}_{2(a q)}+\mathrm{O}_{2(g)}$

(c) The balanced chemical equation for the reaction between Na2O and CO2 is:

$\mathrm{Na}_{2} \mathrm{O}_{(s)}+\mathrm{CO}_{2(g)} \longrightarrow \mathrm{Na}_{2} \mathrm{CO}_{3}$
