1) 2NaOH+H2SO4 =Na2SO4+2H2O
NaOH + Al(OH)3 = Na[Al(OH)4]
NaOH+2H2O = NaOH*2H2O
2NaOH+SO3 =Na2SO4+H2O
2) 2Al(OH)3+3H2SO4 = Al2(SO4)3+3H2O
H2SO4+Na2O = Na2SO4+H2O
H2SO4+H2O = H2SO4*H2O
H2SO4+SO3 =H2S2O7
3) 2Al(OH)3+Na2O = 2NaAlO2+3H2O
2Al(OH)3(свежевыпавший)+ nH2O = Al2O3*(n+3)H2O
2Al(OH)3+3SO3 = Al2(SO4)3+3H2O
4) Na2O+H2O = 2NaOH
Na2O+SO3 = Na2SO4
5) H2O+SO3 = H2SO4
Итого, не реагируют только NaOH и Na2O.
