Write balanced equations for reactions between

(a) Na2O2 and water


(b) KO2 and water


(c) Na2O and CO2.

a) The balanced equations for reactions between Na2O2 and water is given below:


Na2O2 (s) + 2H2O (l) → 2NaOH (aq) + H2O2 (aq)


b) The balanced equations for reactions between KO2 and water is given below:


2KO2 (s) + 2H2O (l) → 2KOH (aq) + H2O2 (aq) + O2 (g)


c) The balanced equations for reactions between Na2O and CO2.is given below:


Na2O + CO2→ Na2CO3
