Carry out transformations: Zinc – Zinc oxide – Zinc nitrate – Zinc hydroxide – Zinc sulfate

1) Zinc reacts with oxygen, resulting in zinc oxide:

2Zn + O2 → 2ZnO;

2) As a result of the exchange reaction of zinc oxide with nitric acid, zinc nitrate and water are obtained:

ZnO + 2HNO3 → Zn (NO3) 2 + H2O;

3) Zinc nitrate reacts with sodium hydroxide, as a result, zinc hydroxide and sodium nitrate are formed:

Zn (NO3) 2 + 2NaOH → Zn (OH) 2 + 2NaNO3;

4) When zinc and sulfuric acid interact, zinc sulfate and water are formed:

Zn (OH) 2 + H2SO4 → ZnSO4 + 2H2O.
