The decomposition of a salt is promoted by the formation of a new compound with high lattice energy. From BeCO3 and BeSO4, BeO will be formed by decomposition. The small doubly charged ions will result in very high lattice energy for BeO which will help to drive the reaction. (Reaction is also favoured by an increase in entropy since a gaseous product is formed).

Why alkali metals are normally kept in kerosene oil?
Alkall metals, when exposed to atmosphere react with oxygen, moisture and CO2 present in the air forming oxides, hydroxide and carbonates. In order to prevent the reaction the alkali metals are stored under kerosene.
