1.	I. A white coloured solid X ( a compound of calcium)gives a highly exothermic reaction with water to form Y, which is used for whitewashing. When CO2 is passed to the aq. The solution of Y, white ppt. of Z is formed. Z undergoes thermal decomposition to form X and CO2. i. Identify X, Y and Z. ii. Write three balanced equations of the reactions taking place in the events described above.
Answer» X = CaO ( QUICK LIME)Y = Ca(OH)2 (Slaked lime)Z = CACO3. ( Calcium Carbonate)(i) Ca + O2 ➡️ CaO(ii). CaO + H2O ➡️ Ca(OH)2 + heat(iii). Ca(OH)2 + CO2➡️ CaCO3 + heat
