Select correct statement(s):
(A) \( \mathrm{Li}_{2} \mathrm{CO}_{3} \) is only sparingly soluble in water and no \( \mathrm{LiHCO}_{3} \) has been isolated.
(B) \( \mathrm{K}_{2} \mathrm{CO}_{3} \) cannot be made by a method similar to the ammonia-soda (Solvay) process.
(C) \( \mathrm{Li}_{2} \mathrm{CO}_{3} \) and \( \mathrm{MgCO}_{3} \) both are thermally stable.
(D) \( \mathrm{KCl} . \mathrm{MgCl}_{2} \cdot 6 \mathrm{H}_{2} \mathrm{O} \) is a mineral called carnallite.
