A compound 'X' is
i. It is given that ‘X’ is a constituent of baking powder and used antacid. This means ‘X’ is sodium bicarbonate.
ii. When sodium bicarbonate (X) is heated, it produces sodium carbonate, carbon dioxide, and water. The reaction is given as:
NaHCO3 + Heat → Na2CO3 + CO2 + H2O
iii. When CO2 (Y) produced in the reaction is passed through lime water (calcium hydroxide) turns it milky and form salt, i.e., calcium carbonate (Z). The reaction is given as:
Ca(OH)2 + CO2→ CaCO3 + H2O
Thus, X is Na2CO3, Y is NaHCO3, and Z is CaCO3.
