The treatment of galena with HNO3\mathrm{HNO}_{3} produces a gas that is

  1. Option A:

    paramagnetic

    Correct
  2. Option B:

    bent in geometry

  3. Option C:

    an acidic oxide

  4. Option D:

    colorless

    Correct

Answer: A, D

Step-by-step solution

3PbS+8HNO3⟶3 Pb(NO3)2+3 S+2NO↑+4H2O3 \mathrm{PbS}+8 \mathrm{HNO}_{3} \longrightarrow 3 \mathrm{~Pb}\left(\mathrm{NO}_{3}\right)_{2}+3 \mathrm{~S}+2 \mathrm{NO} \uparrow+4 \mathrm{H}_{2} \mathrm{O} NO→\mathrm{NO} \rightarrow paramagnetic, neutral oxide and colourless gas
