NH(4)Cl(aq)+NaNO(2)(aq) overset("heat") ...

`NH_(4)Cl(aq)+NaNO_(2)(aq) overset("heat") to`

A

(B) is an amphoteric oxide

B

(X) is a colourless, diamagnetic gas which combines with Al on heating

C

(X) can be produced by action of `(Zn+NaOH)` on `NaNO_(2)`

D

(X) is coloured, paramagnetic gas which combines with `Al` on heating

Text Solution

Verified by Experts

The correct Answer is:
B
`NH_(4)OH.HCl+NaNO_(2)rarr N_(2)Ooverset(Cu)rarr underset("(Basic Oxide)")(underset("(B)")(CuO))+underset((x))(N_(2))`
(Colourless, dia magnetic)
`2Al+N_(2)rarr 2AlN`
`Zn+NaOH rarr (H_(2)).` The evolved `H_(2)` reduces `NaNO_(2)` to form `NH_(3)` gas
