Question

Химия: Fe-fe2 (so4)3-fe (oh)3-fe2o3-fe-fes-h2s-so2-so3-h2so4-naso4-baso4 !

назым24 · Answer

2Fe + 6H2SO4(конц.) = Fe2(SO4)3 + 3SO2↑ + 6H2O
Fe2(SO4)3 + 6NaOH = 3Na2SO4 + 2Fe(OH)3↓
2Fe(OH)3 = Fe2O3 + 3H2O
Fe2O3 + 3CO = 2Fe + 3CO2↑
Fe + S = FeS
FeS + H2SO4 = FeSO4 + H2S↑
2H2S + 3O2 = 2H2O + 2SO2↑
2SO2 + O2 = 2SO3
H2O + SO3 = H2SO4
H2SO4 + 2NaOH = Na2SO4 + 2H2O
Na2SO4 + Ba(OH)2 = BaSO4↓ + 2NaOH
