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) `Na_(2)O_(2) (s) + 2H_(2)O (l) to 2 NaOH (aq) + H_(2)O_(2) (aq)`
(b) `2KO_(2) (s) + 2H_(2)O (l) to 2 KOH (aq) + H_(2)O_(2) (aq) + O_(2)(g)`
or `4 KO_(2) (s) + 2H_(2)O (l) to 4KOH (aq) + 3O_(2) (g) `
(c) `Na_(2) O + CO_(2) to Na_(2) CO_(3)`
