There is loss in mass when mixture of \( \mathrm{Li}_{2} \mathrm{CO}_{3} \) and \( \mathrm{Na}_{2} \mathrm{CO}_{3} \cdot 10 \mathrm{H}_{2} \mathrm{O} \) is heated strongly. The loss is due to:
(A) \( \mathrm{Li}_{2} \mathrm{CO}_{3} \) only
(B) \( \mathrm{Na}_{2} \mathrm{CO}_{3} \cdot 10 \mathrm{H}_{2} \mathrm{O} \) only
(C) both \( \mathrm{Li}_{2} \mathrm{CO}_{3} \) and \( \mathrm{Na}_{2} \mathrm{CO}_{3} \cdot 10 \mathrm{H}_{2} \mathrm{O} \)
(D) none of the above
