A white solid (x) when heated evolves a colourless gas which does not support combusion. The residue tis dissolved in water to form (y) which can be used for white washing. When excess of `CO_(2)` is bubbled through the solution of (y), it gives a compound (z) which upon heating forms (x) Identify the compound (x).

A white solid (A) when heated liberates a colourless gas which does not support combustion. The residue is dissolved in water to form (B) which can be used for whitewashing. When excess of CO_2 gas is passed through the solution of (B), it gives a compound {C) which on heating forms (A). Identify (A), (B) and (C). Give the reactions.

A solid 'X' when heated evolves a colourless gas which does not support combustion. The residue is dissolved in water to form 'Y' which can be used during construction and white washing. When excess carbon dioxide is bubbled through the solution of 'Y' , compound 'Z' is formed. When 'Z' is heated gently, 'X' is reformed. Identify 'X' and discuss the reactions.

The compound 'A' on heating gives a colourless gas and a residue. The residue dissolves in water to obtain (B). When excess of CO_(2) is bubbled through aqueous solution of B gentle heating gives back A. Compound 'C' is

The compound X on heating gives a colourless gas. The residue is dissolved in water to obtain Y Excess CO_2 is bubbled through aqueous solution of Y, Z is formed. Z on gentle heating gives back X. The compound X is:

A substance ‘A’ on heating gives a Colourless gas. The residue is dissolved In water to form ‘B’. When excess of co_2 in bubbled through a solution of ‘B’, ‘C’ is formed. ‘C’ on gently heating forms ‘A. Then the substance ‘A’ is

A compound X on heating gives a colourless gas. This residue is dissolved in water to obtain Y. excess CO_(2) is bubbled through aqueous solution of Y, Z is formed. Z on gentle heating give back X. the X is

A compound X on heating gives a colourless gas. This residue is dissolved in water to obtain Y. excess CO_(2) is bubbled through aqueous solution of Y, Z is formed. Z on gentle heating give back X. the X is
