Complete the reaction chain
S → SO₂ → SO₃ → H₂SO₄ → SO₂ → H₂SO₃ → Na₂SO₃ → SO₂
Help me. Thanks a lot.

Here's a complete reaction chain for the given transformations:
S + O₂ → SO₂
2SO₂ + O₂ → 2SO₃
SO₃ + H₂O → H₂SO₄
2H₂SO₄ + S → 2H₂O + 3SO₂
SO₂ + H₂O → H₂SO₃
H₂SO₃ + 2NaOH → Na₂SO₃ + 2H₂O
Na₂SO₃ → SO₂ + Na₂O

thank you!
