      4KO2 (s) + 2CO2 (g) ï£§ï£§â†’ 2K2CO3(s) + 3O2 (g)

The solubility of alkaline earth metal oxides in water increases down
the group. BeO and MgO are insoluble but CaO, SrO and BaO are
soluble and react with water to form the corresponding hydroxides.

The basic character of the oxides of alkaline earth metals
increases down the group. The tendency for group IIA oxides to
form alkaline solution is relatively less than that of alkali metals .

                           Source and Credit: Learn

BeO is amphoteric in nature since it reacts with both acids and bases.
