Химия помогите пожалуйста даю макс баллов

Answer 1

Ответ:

2) Al2O3 + 6HCl = 2AlCl3 + 3H2O

AlCl3 + 3NaOH = Al(OH)3 + 3NaCl

Al(OH)3 + NaOH = Na[Al(OH)4]

2Al(OH)3 + 3H2SO4 = Al2(SO4)3 + 6H2O

2CuS + 3O2 = 2CuO + 2SO2

CuO + 2HCl = CuCl2 + H2O

CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl

Cu(OH)2 + H2SO4 = CuSO4 + 2H2O

Fe + CuSO4 = FeSO4 + Cu

Fe3O4 + 4H2 = 4H2O + 3Fe

Fe + 2HCl = FeCl2 + H2

FeCl2 + 2NaOH = Fe(OH)2 + 2NaCl

4Fe(OH)2 + O2 + 2H2O = 4Fe(OH)3

2Fe(OH)3 + 3H2SO4 = Fe2(SO4)3 + 6H2O

AlCl3 + 3NaOH = Al(OH)3 + 3NaCl

Al(OH)3 + NaOH = Na[Al(OH)4]

2Al(OH)3 + 3H2SO4 = Al2(SO4)3 + 6H2O
