(C) The reaction of galena $(PbS)$ with dilute nitric acid $(HNO_3)$ is given by:$3PbS + 8HNO_3 \rightarrow 3Pb(NO_3)_2 + 2NO + 4H_2O + 3S$The gas produced is nitric oxide $(NO)$.Properties of $NO$:$1$. It is paramagnetic due to the presence of an odd number of electrons ($11$ valence electrons).$2$. It has a linear geometry.$3$. It is a neutral oxide (not acidic).$4$. It is a colorless gas.Therefore,the gas $NO$ is paramagnetic $(A)$ and colorless $(D)$.

The treatment of galena $(PbS)$ with $HNO_3$ produces a gas that is:
