Na2O + H2O= NiO+H2O= CaO+HCl= SO3+CaO= SO3+NaOH= P2O5+Na2O= ZnO+HCl= ZnO+KOH=

Question

Na2O + H2O= NiO+H2O= CaO+HCl= SO3+CaO= SO3+NaOH= P2O5+Na2O= ZnO+HCl= ZnO+KOH=

Answer 1

Na2O + H2O = 2NaOH

NiO+H2O= не идет

CaO + 2HCl = CaCl2 + H2O

SO3+CaO=CaSO4

SO3 + 2NaOH = Na2SO4 + H2O

P2O5 + 3Na2O = 2Na3PO4

ZnO + 2HCl = ZnCl2 + H2O

ZnO + 2 KOH + 2 H2O = K2[Zn(OH)4]
