Acids - Acids are compounds which give hydrogen ion in water solution. For example, Hydrochloric acid (HCl), Sulphuric acid(H2SO4), Nitric acid(HNO3).Two properties of acids :
(i) Acids reacts with metal to form salt and hydrogen gas.(ii) Acids react with metal carbonate or metal hydrogen carbonate to produce salt, carbon dioxide and water.

Answer:
Let us consider X metal as Zinc here. Zinc reacts with dil. HCl to form zinc chloride and hydrogen gas.
Zn + dil 2HCl --------- ZnCl2 + H2↑
Here the compound Y is any metal carbonate or metal bicarbonate which reacts with dil. HCl to form salt, water and CO2 gas is evolved. Let us consider here Y as sodium carbonate or sodium bicarbonate.
Na2CO3 + 2HCl → 2 NaCl + H2O + CO2↑
NaHCO3 + HCl → NaCl + H2O + CO2↑
When carbon dioxide is passed through lime water, it turns milky.
Ca(OH)2 + CO2 → CaCO3+ H2O
Hence X is Zinc
Y is sodium carbonate or bicarbonate
