Sulfur can be transformed into sodium sulfate through a series of chemical reactions:

Sulfur (S) is converted into hydrogen sulfide (H2S) by reacting it with hydrogen gas (H2).Hydrogen sulfide (H2S) is oxidized to sulfur dioxide (SO2) by reacting it with oxygen (O2).Sulfur dioxide (SO2) is further oxidized to sulfur trioxide (SO3) by reacting it with more oxygen.Finally, sulfur trioxide (SO3) reacts with sodium hydroxide (NaOH) to form sodium sulfate (Na2SO4).

By following these steps, sulfur can be transformed into sodium sulfate.
