The white precipitate (Y), obtained on passing colourless and odourless gas (X) through an ammoniacal solution of NaCl, loses about 37% of its weight on heating and a white residue (Z) of basic nature is left. Identify (X), (Y) and (Z) from following sets.

A

`{:("(X)","(Y)","(Z)"),(N_(2), (NH_(4))_(2)CO_(3),NH_(4)Cl):}`

B

`{:("(X)","(Y)","(Z)"),(O_(2),NaNH_(4)CO_(3),NaHCO_(3)):}`

C

`{:("(X)","(Y)","(Z)"),(CO_(2), NH_(4)HCO_(3),(NH_(4))_(2)CO_(3)):}`

D

`{:("(X)","(Y)","(Z)"),(CO_(2), NaHCO_(3),Na_(2)CO_(3)):}`

When dilute HCI is added to a white substance (A), a colourless gas (B) is evolved. When the gas (B) is passed through clear lime water, a white precipitate ( C) is obtained. The precipitate dissolves when excess of the gas (B) is passed through the lime water. The residue obtained on heating the solid substance (A) is yellow when hot but white when cold. When the gas (B) is passed through red hot charcoal, another gas (D) is obtained. The gas (D) gets absorbed in arnmoniacal cuprous chloride solution . Identify (A), (B), (C) and (D) and give the relevant reactions.

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.
