1.
2Na +2 H2O=2NaOH + H2
2H2O = 2H2 + O2
CaO +H2O=Ca(OH)2
SO3 + H2O=H2SO4
Cl2 + H2O=HCl + HClO
HClO-----> HCl + [O]
3Fe +4H2O=Fe3O4 +4H2
2.
-M + H2O------> B + H2 [ B= baza]
2K+2H2O=2KOH +H2
-M + H2O-----> oxid + H2 [M= metal ]
3Fe + 4H2O=Fe3 O4 +4 H2
-Nemetal + H2O-------> Acid1 + Acid2
Cl2 + H2O-----> HCl + HClO
-O.B. + H2O-------> BAZA [ O.B.=oxid bazic ]
CaO +H2O=Ca(OH)2
-O.A. +H20=Acid [O.A.=oxid acid ]
SO3 +H2O=H2SO4
