The first reaction sequence shows the conversion of hydrogen sulfide (H2S) to sulfur dioxide (SO2), then to sulfur trioxide (SO3), followed by the formation of sodium sulfate (Na2SO4) and barium sulfate (BaSO4).
The second reaction sequence involves the conversion of sulfuric acid (H2SO4) to magnesium sulfate (MgSO4).
