`CO_(2)` gas along with solid `(Y)` is obtained when sodium salt `(X)` is heated. `(X)` is again obtained when `CO_(2)` has is passed into `(Y)`. `X` & `Y` are-

A

`Na_(2)CO_(3), Na_(2)O`

B

`Na_(2)CO_(3), NaOH`

C

`NaHCO_(3), Na_(2)CO_(3)`

D

`Na_(2)CO_(3), NaHCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset((X))(2NaHCO_(3)) overset("Heat")(rarr) underset((Y))(Na_(2)CO_(3))+H_(2)O+CO_(2)`
`underset((Y))(Na_(2)CO_(3))+H_(2)O+CO_(2) rarr underset((X))(2NaHCO_(3))`

When H_(2)S is passed through an ammonical salt solution X, a white precipitate is obtained. Then X can be a-

A white precipitate (X) is formed when a mineral (A) is boiled with Na_(2)CO_(3) solution. The precipitate is filtered and filtrate contains two compound (Y) and (Z). The compound (Y) is removed by crystallization and when CO_(2) is passed through the filtrate obtained after crystallization, then (Z) changed to (Y) . When compound (Y) is heated, it gives two compounds (Z) and (T). Compound (T) on heating with cobalt oxide produces blue coloured substance (S) The compound (Y) in the filtrate when (A) is boiled with Na_(2)CO_(3) is

A yellow metallic powder is burnt in a stream of fluorine to obtain a colourless gas X which is thermally stable and chemically inert. Its molecule has octahedral geometry. Another colourless gas Y with same constituent atoms as that of X is obtained when sulphur dichloride is heated with sodium fluoride. Its molecule has trigonal pyramidal structure. X and Y are respectively of fluorine to obtain a colourless gas X which is thermally stable and chemically inert. Its molecule has octahedral geometry.
