Write balanced equations for reactions between
a. `Na_(2)O_(2)` and water
b. `KO_(2)` and water
c. `Na_(2)O` and `CO_(2)`

Explanation

(a) The balanced chemical equation for the reaction between `Na_(2)O_(2)` and water is:
`2Na_(2)O_(2(s)) + 2H_(2)O_((l)) rarr 4NaOH_((aq))+O_(2(aq))`
(b) The balanced chemical equation for the reaction between `KO_(2)` and water is:
`2KO_(2(s))+2H_(2)O_((l)) rarr 2KOH_((aq))+H_(2)O_(2(aq))+O_(2(g))`
(c) The balanced chemical equation for the reaction between `Na_(2)O` and `CO_(2)` is:
`Na_(2)O_((s))+CO_(2(g))rarr Na_(2)CO_(3)`
