Yes, sulfur reacts with dilute mineral acids to displace hydrogen gas. This is because sulfur is more reactive than hydrogen in the reactivity series of elements. Therefore, it can replace hydrogen from acids, forming hydrogen sulfide gas (H2S) in the process.

The general reaction for this displacement reaction can be represented as:

S(s) + 2HCl(aq) → H2S(g) + 2Cl(aq)

In this reaction, solid sulfur (S) reacts with hydrochloric acid (HCl) in an aqueous solution. Hydrogen sulfide gas (H2S) is produced as a result of the displacement of hydrogen ions (H+) from the acid by sulfur atoms. Chlorine ions (Cl-) are formed as a byproduct of this reaction.
