Al->Al2O3->AlCl3->Al(OH)3->KAlO2​

Question

Al->Al2O3->AlCl3->Al(OH)3->KAlO2​

Answer 1

4Al + 3O2 = 2Al2O3

Al2O3 + 6HCl = 2AlCl3 + 3H2O

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

2Al(OH)3 + K2O (t)= 2KAlO2 + 3H2O

Comments

в первом не 2О3, а 3О2

спасибо, клавиатура тормознула ;)

Answer 2

4Al + 3O2 = 2Al2O3

Al2O3 + 6HCl = 2AlCl3 + 3H2O

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

2Al(OH)3 + K2O =(t°) 2KAlO2 +3H2O
