1. Zn + H2SO4 = ZnSO4 + H2
Displacement reaction has taken place coz Zn is more reactive than hydrogen
2. Zn + HCl = ZnCl + H2
Displacement reaction has taken place
3.Zinc reacts with dilute Nitric acid to produce Zinc nitrate, nitric oxide and water
3Zn + 8HNO₃ → 3Zn(NO₃)₂ + 2NO + 4H₂O
Zinc reacts with concentrated Nitric acid to produce Zinc nitrate, nitrogen dioxide and water.
Zn + 4HNO₃ → Zn(NO₃)₂ + 2NO₂ + 2H₂O
4.Zn + NaCl no reaction take place coz sodium is more reactive than zinc
5.Zn + NaOH = Na2ZnO2 + H2
Displacement reaction has taken place coz Zn is more reactive than hydrogen
