1. ZnO + 2HCl = ZnCl₂ + H₂O
2. ZnCl₂ + 2NaOH = Zn(OH)₂ + 2NaCl
3. Zn(OH)₂ + 2NaOH = Na₂[Zn(OH)₄]
4. Na₂[Zn(OH)₄] + 2HNO₃ = 2NaNO₃ + Zn(OH)₂ + 2H₂O
ZnO + 2HCl = ZnCl2 + H2O
1. ZnO + 2HCl = ZnCl₂ + H₂O
2. ZnCl₂ + 2NaOH = Zn(OH)₂ + 2NaCl
3. Zn(OH)₂ + 2NaOH = Na₂[Zn(OH)₄]
4. Na₂[Zn(OH)₄] + 2HNO₃ = 2NaNO₃ + Zn(OH)₂ + 2H₂O
ZnO + 2HCl = ZnCl2 + H2O
