(A) When sodium sulfide $(Na_2S)$ reacts with dilute hydrochloric acid $(HCl)$,hydrogen sulfide gas $(H_2S)$ is evolved.
$Na_2S + 2HCl ightarrow 2NaCl + H_2S \uparrow$
Hydrogen sulfide gas $(H_2S)$ is known for its characteristic rotten egg smell and its ability to turn lead acetate paper black due to the formation of lead sulfide $(PbS)$:
$Pb(CH_3COO)_2 + H_2S ightarrow PbS \downarrow (	ext{black}) + 2CH_3COOH$

The gas evolved when sodium sulfide is heated with dilute $HCl$ is:
