________与水反应：_________________________与酸反应：
Na2O + H2O = 2NaOH__________________Na2O + 2H+ = 2Na+ + H2O
2Na2O2 + 2H2O = 4NaOH + O2__________2Na2O2 + 4H+ = 2Na+ + O2 + 2H2O
Mg3N2 + 6H2O = 3Mg(OH)2 + 2NH3______Mg3N2 + 8H+ = 3Mg2+ + 2NH4+
2K + 2H2O = 2KOH + H2_______________2K + 2H+ = 2K+ + H2
NaH + H2O = NaOH + H2_______________NaH + H+ = Na+ + H2
