1. 2Na+ Cl2 = 2NaCl
2. NaCl + HNO3= NaNO3+HCl
3. NaNO3+H2SO4 =Na2SO4 +HNO3
4. NaSO4+2KOH =2NaOH+K2SO4
5. NaOH+HCl=NaCl+H2O
6. NaOH+H3PO4 =Na3PO4+H2O
7. Mg + HF=MgF2+H2O
8. 6HCl +2HNO3=2NO+3Cl+4H2O
9. Au + H2O=Au2O +H2

MgO + 2 HF = MgF2 + H2O
6HCl + 2HNO3 = 2NO + 3Cl2 + 4H2O
Au + H2O=AuO+H2
(но это не точно)
