      Compound 'A' when dissolved in water gives compound 'B' and liberates heat. Compound 'A' is used in whitewashing. Compound 'B' reacts with CO^ to form a white precipitate of compound 'C'. Identify compounds 'A', 'B' and 'C'. Also write the equations involved.

    Answer:

                 Quicklime (CaO) is used for white washing. So 'A' is CaO.                                 'B' is Ca(OH)2.                 'C' is CaCO3.
