Question

Составьте уравнения реакций
Na2O + H2O = N2O5 + H2O =

CaO + HNO3 = NaOH + P2O5 =

K2O + CO2 = Cu(OH)2 = ? + ?

ВaO + HNO3 = КOH + P2O5 =

К2O + H2O = Р2O5 + H2O =

K2O + SO2 = Fe (OH)2 = ? + ?

Answer 1

Na2O + H2O = 2NaOH

N2O5 + H2O = 2HNO3

CaO + 2HNO3 = Ca(NO3)2 + H2O

6NaOH + P2O5 = 2Na3PO4 +3 H2O

K2O + CO2 = K2CO3

Cu(OH)2 = CuO + H2O

BaO + 2HNO3 = Ba(NO3)2 + H2O

6KOH + P2O5 = 2K3PO4 + 3H2O

K2O + H2O = 2KOH

P2O5 + 3H2O = 2H3PO4

K2O + SO2 = K2SO3

Fe(OH)2 = FeO + H2O
