1. 2K+ H2 = 2KH
2. 2NA +S = Na2S
3.Na2O2 + 2Na = 2Na2O
4.2Na + 2H2O = 2NaOH + H2
5. 2K + 2HCl = 2KCl + H2
6.Na2O + 2HCl ( разб.) = 2NaCl + H2O
7. 2NaOH (горячий) + Сl2 = NAClO + NaCl + H2O
8. NaOH (недостаток ) + СO2 = NaHCO3
9.2NaOH (конц.) + Al2O3 + 3H2O = 2Na [Al (OH)4 ]
10. 2NaOH (конц.) + Zn + 2H2O = Na2 [ Zn (OH)4 ] + H2
