Hydrogen sulfide (H2S) reacts with oxygen to form elemental sulfur (S), which further reacts with oxygen to form sulfur dioxide (SO2). Sulfur dioxide then reacts with sodium hydroxide (NaOH) to form sodium sulfite (Na2SO3), which further reacts with barium chloride (BaCl2) to form barium sulfate (BaSO4).
