SO3 + H2O = H2SO4
N2O5 + Ca(OH)2 = Ca(NO3)2 + H2O
MgO + SO3 = MgSO4
Na2O + H2O = 2NaOH
ZnO + H2O = Zh(OH)2
ZnO + N2O5 = Zn(NO3)2
Ba + H2O = Ba(OH)2
Cu(OH)2 = CuO + H2O
Ca(OH)2 + SO2 = CaSO3 + H2O
H2SO4 + MgO = MgSO4 + H2O
3H2SO4 + Al2O3 = Al2(SO4)3 + 3H2O
SO3 + 2KOH = K2SO4 + H2O
HNO3 + NaOH => NaNO3 + H2O
H + NO3 + Na + OH = Na + NO3 + H2O
