Відповідь:
1. 2Fe + O₂ = 2FeO
2. FeO + 2HCl = FeCl₂ + H₂O
3. FeCl₂ + 2KOH = Fe(OH)₂ + 2KCl
1.4Al+3O2=2Al2O3
2.Al2O3+3H2SO4=Al2(SO4)3+3H2O
3.Al2(SO4)3+6KOH=3K2SO4+2Al(OH)3
4.2Al(OH)3=(t)Al2O3+3H2O
5.2 Al2O3 → Al + 3 AlO2
1. S+O2=SO2
2. 2SO2+O2=2SO3
3. SO3+H2O=H2SO4
4. H2SO4+Ba(OH)2=BaSO4+2H2O
5.BaSO4→SO3 + BaO
Fe+ O = FeO
FeO+ HCl = FeCl2
FeCl + LiOH = Fe ( OH)2 + LiCl
