Vedclass · Answer

(A) Milk of magnesia is a suspension of $Mg(OH)_2$ in water,not $MgO + H_2O$. Therefore,statement $A$ is false.Alkali metal peroxides $(M_2O_2)$ become more stable as the size of the alkali metal cation increases down the group due to the stabilization of the large peroxide ion by the large cation.$AgF$ is soluble in water because its hydration energy is higher than its lattice energy.Anhydrous $MgCl_2$ undergoes hydrolysis upon heating $MgCl_2 \cdot 6H_2O$ to form $Mg(OH)Cl$ and $HCl$,so it cannot be prepared by direct heating.
