This sequence represents the reaction pathway of the conversion of zinc metal (Zn) to zinc sulfate (ZnSO4) through various intermediates.

Zn reacts with oxygen to form zinc oxide (ZnO).Zinc oxide reacts with water to form zinc hydroxide (Zn(OH)2).Zinc hydroxide reacts with zinc oxide to form a mixture of zinc hydroxide and zinc oxide.The mixture reacts with hydrochloric acid (HCl) to form zinc chloride (ZnCl2).Finally, zinc chloride reacts with sulfuric acid (H2SO4) to form zinc sulfate (ZnSO4).
