Na→Na2O→NaOH→Na2SO4→BaSO4→BaCI2→Ba (OH)2

Answers & Comments

kovpakua Na2O2 + 2Na = 2Na2O

Na2O + H2O = 2NaOH

FeCl3 + 3NaOH → Fe(OH)3↓ + 3NaCl

2NaCl+BaSO4=Na2SO4+BaCl2

BACL2+2H2O=BA(OH)2+2HCL

Fe(NO3)2 + Ba(OH)2 = Fe(OH)2 + Ba(NO3)2

Fe(OH)2 = FeO + H2O

FeO + H2SO4(разб.) = FeSO4 + H2O

FeSO4 + H2 = H2SO4 + Fe
