\( \mathrm{P} \) compound \( X \). Boiling this sample converts \( X \) to
W compound Y. X and Y, respectively, are

(1) \( \mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2} \) and \( \mathrm{CaO} \)
(2) \( \mathrm{Mg}\left(\mathrm{HCO}_{3}\right)_{2} \) and \( \mathrm{MgCO}_{3} \)
(3) \( \mathrm{Mg}\left(\mathrm{HCO}_{3}\right)_{2} \) and \( \mathrm{Mg}(\mathrm{OH})_{2} \)
(4) \( \mathrm{Ca}(\mathrm{HCO} 3)_{2} \) and \( \mathrm{Ca}(\mathrm{OH})_{2} \)
