(a) \(\mathrm{Na}_2 \mathrm{O}_2(\mathrm{~s})+2 \mathrm{H}_2 \mathrm{O}(\ell) \longrightarrow 2 \mathrm{NaOH}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}_2(\mathrm{aq})\)
(b) \(2 \mathrm{KO}_2(\mathrm{~s})+2 \mathrm{H}_2 \mathrm{O}(\ell) \longrightarrow 2 \mathrm{KOH}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}_2(\mathrm{aq})+\mathrm{O}_2(\mathrm{~g})\)
(c) \(\mathrm{Na}_2 \mathrm{O}+\mathrm{CO}_2 \longrightarrow \mathrm{Na}_2 \mathrm{CO}_3\)
(b) \(2 \mathrm{KO}_2(\mathrm{~s})+2 \mathrm{H}_2 \mathrm{O}(\ell) \longrightarrow 2 \mathrm{KOH}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}_2(\mathrm{aq})+\mathrm{O}_2(\mathrm{~g})\)
(c) \(\mathrm{Na}_2 \mathrm{O}+\mathrm{CO}_2 \longrightarrow \mathrm{Na}_2 \mathrm{CO}_3\)
