NH3-NH4Cl-NaCl-Na2SO4-NaOH-Na3PO4

Answer 1

NH3+HCl=NH4Cl
NH4Cl+NaOH=NaCl+NH3+H2O
2NaCl+H2SO4=Na2SO4+2HCl
Na2SO4+Ba(OH)2=2NaOH+BaSO4(осадок)
3NaOH+H3PO4=Na3PO4+3H2O

Answer 3

1. NH3+HCl=NH4Cl
2. NH4CL + NaOH (t) = NH3 + NaCl + H2O
3. 2NaCl+PbSO4 = Na2SO4+PbCl2
4. Na2SO4 + Ba(OH)2 = BaSO4↓ + 2NaOH
5. NaOH + Na2HPO4 = Na3PO4 +H2O
