4Al + 3O2 = 2Al2O3
Al2O3 + 3H2 = 2Al + 3H2O
2Al+3Cl2 = 2AlCl3
AlCl3 + 3NaOH = Al(OH)3 + 3NaCl
2Al(OH)3 =t=> Al2O3 + 3H2O
2Al(OH)3 + 3H2SO4 = Al2(SO4)3 + 6H2O
Al2(SO4)3 + 3Ba(NO3)2 = 2Al(NO3)3 + 3BaSO4↓
S + O2 = SO2
2Al+3S = Al2S3
2Al2S3 + 9O2 = 2Al2O3 + 6SO2
SO2 + 2KOH = K2SO3 + H2O
K2SO3 + 2HCl = 2KCl + H2O + SO2↑
2SO2+O2 = 2SO3
SO3 + 2NaOH = Na2SO4 + H2O
SO3 + H2O=H2SO4
3H2SO4 + 2Fe(OH)3 = Fe2(SO4)3 + 6H2O
Fe2(SO4)3 + 6NaOH = 2Fe(OH)3 + 3Na2SO4
2Fe(OH)3 =t=> Fe2O3+3H2O
Fe2O3 + 3C = 2Fe + 3CO
