The reactions involved in this sequence are as follows:

1) Zn + ZnS → ZnS (This is the reaction where zinc reacts with zinc sulfide to form zinc sulfide)
2) ZnS + 2H2S → 2ZnS + 2H2S (This is the reaction where zinc sulfide reacts with hydrogen sulfide to form zinc sulfide and hydrogen sulfide)
3) ZnS + O2 → ZnSO2 (This is the reaction where zinc sulfide reacts with oxygen to form zinc sulfate)
4) 2ZnSO2 + O2 → 2ZnSO3 (This is the reaction where zinc sulfate reacts with oxygen to form zinc sulfite)
5) 2ZnSO3 + 2H2O → 2ZnSO4 + 3H2O (This is the reaction where zinc sulfite reacts with water to form zinc sulfate)
6) BaSO4 + H2SO4 → BaSO4 (This is the reaction where barium sulfate reacts with sulfuric acid to form barium sulfate)

These reactions show the transformation of zinc, zinc sulfide, hydrogen sulfide, oxygen, sulfur dioxide, sulfur trioxide, water, barium sulfate, and sulfuric acid.
