Объяснение:
AlCl3 + 3NaOH = Al(OH)3↓ + 3NaCl
Al(OH)3 + NaOH = Na[Al(OH)4]
2AlCl3 -> 2Al + 3Cl2
2Al + 3H2SO4 = Al2(SO4)3 + 3H2↑
AlCl3 + 3AgNO3 = Al(NO3)3 + 3AgCl↓
Al(NO3)3 + 3NaOH = Al(OH)3↓ + 3NaNO3
2Al(OH)3 = Al2O3 + 3H2O
Fe + 2HCl = FeCl2 + H2↑
FeCl2 + 2NaOH = Fe(OH)2↓ + 2NaCl
4Fe(OH)2 + O2 + 2H2O = 4Fe(OH)3
3Fe + 2O2 = Fe3O4
2Fe +3Cl2 = 2FeCl3
FeCl3+ 3NaOH = Fe(OH)3↓ + 3NaCl
2Fe(OH)3 = Fe2O3 + 3H2O
