Write balanced equations for reactions between
$(a)$ $Na_{2}O_{2}$ and water
$(b)$ $KO_{2}$ and water
$(c)$ $Na_{2}O$ and $CO_{2}$

(N/A) The balanced chemical equation for the reaction between $Na_{2}O_{2}$ and water is:
$2Na_{2}O_{2(s)} + 2H_{2}O_{(l)} \longrightarrow 4NaOH_{(aq)} + O_{2(g)}$
$(b)$ The balanced chemical equation for the reaction between $KO_{2}$ and water is:
$2KO_{2(s)} + 2H_{2}O_{(l)} \longrightarrow 2KOH_{(aq)} + H_{2}O_{2(aq)} + O_{2(g)}$
$(c)$ The balanced chemical equation for the reaction between $Na_{2}O$ and $CO_{2}$ is:
$Na_{2}O_{(s)} + CO_{2(g)} \longrightarrow Na_{2}CO_{3(s)}$
