MCQ

The treatment of galena with $HNO _3$ produces a gas that is

$(A)$ paramagnetic $(B)$ bent in geometry $(C)$ an acidic oxide $(D)$ colorless

A
$A,B$
B
$A,C$
✓
$A,D$
D
$A,B,C$

✓

Answer

Correct option: C.

$A,D$

c
$3 PbS +8 HNO _3 \rightarrow 3 Pb \left( NO _3\right)_2+2 NO +4 H _2 O + S$

NO $\Rightarrow$ Neutral oxide, Paramagnetic, Linear geometry, Colourless gas
