Question:

Write balanced equations for reactions between

(a) Na2O2and water

(b) KO2 and water

(c) Na2O and CO2

Answer:

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

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

 

(b) The balanced chemical equation for the reaction between KO2 and water is:

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

 

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

Na2O(s)  +  CO2(g)   →   Na2CO3
