Vedclass · Answer

(A) Potassium superoxide $( KO_{2} )$ reacts with water to produce potassium hydroxide,hydrogen peroxide,and oxygen gas. This reaction is represented as follows:$ 2 KO_{2} + 2 H_{2} O \rightarrow 2 KOH + H_{2} O_{2} + O_{2} $In contrast,other metal oxides react differently:$ Na_{2} O_{2} + 2 H_{2} O \rightarrow 2 NaOH + H_{2} O_{2} $ (Produces peroxide but no oxygen)$ CaO + H_{2} O \rightarrow Ca(OH)_{2} $ (Produces hydroxide only)$ Li_{2} O + H_{2} O \rightarrow 2 LiOH $ (Produces hydroxide only)

$A$ metallic oxide reacts with water to form its hydroxide,hydrogen peroxide,and also liberates oxygen. The metallic oxide could be
