[Trần Minh Ngọc]

1. Ba(NO3)2 + H2SO4 => 2HNO3 + BaSO4 ↓

2. Fe(NO3)3 + 3NaOH => 3NaNO3 + Fe(OH)3 ↓

3. ZnCl2 + Mg => MgCl2 + Zn

4. H2SO4 + Cu(OH)2 => CuSO4 + 2H2O

5. Na2CO3 + 2HCl => 2NaCl + H2O + CO2 ↑

6. 2NaHCO3 + Ba(OH)2 => Na2CO3 + BaCO3 ↓ + 2H2O

7. BaCl2 + FeSO4 => BaSO4 ↓ + FeCl2

8. AgNO3 + HCl => HNO3 + AgCl ↓

9. CaCl2 + 2AgNO3 => 2AgCl ↓ + Ca(NO3)2

10. BaCl2 + Na2CO3 => 2NaCl + BaCO3 ↓

11. BaS + H2SO4 => BaSO4 ↓ + H2S ↑

12. BaSO3 + 2HCl => BaCl2 + H2O + SO2 ↑

13. Ba(HCO3)2 + CaCl2 => BaCl2 + CaCO3 ↓ + H2O + CO2 ↑
