`NH_(4)CI +Na_(2)HPO_(4)+4Z rarr underset(("sparingly soluble salt"))(A)+ NaCI A overset(Delta)rarr A' +4Z`
`A' overset(Delta)underset("High" T)rarr X+Y uarr +Z`
Compound (Z) is a neutral oxide and turns anhydrous `CuSO_(4)` blue. Gas (Y) is a basic gas which can also be obtained by treating ammonium sulphate with lime water. sequences mentioned above involve balanced reactions.
Which of the following reactions would produce gas Y?

Options

A. `Mg_(3)N_(2)+H_(2)O rarr`
B. `Zn+NaOH +NaNO_(3) overset(Delta)rarr`
C. `(NH_(4))_(2)CO_(3) overset(Delta)rarr`
D. All of the above

Answer

D

Explanation

`Z rarr H_(2)O, A rarr Na(NH_(4))HPO_(4).4H_(2)O, X rarr NaPO_(3)`
`Y rarr NH_(3),A' rarr Na(NH)_(4)HPO_(4)`
