Question

решить химиия срочно плиз

Answer 1

4Al + 3O2 -> 2Al2O3
Al2O3 + 6HCl -> 2AlCl3 + 3H2O
AlCl3 + 3NaOH -> Al(OH)3 + 3NaCl
2Al(OH)3 + 3H2SO4 -> Al2(SO4)3 + 6H2O
Al2(SO4)3 + 6NaOH ->2 Al(OH)3 + 3Na2SO4

Answer 2

Al->Al2O3->AlCl3->Al(OH)3->Al2(SO4)3->Al(OH)3
4Al+3O2->2Al2O3
Al2O3+6HCl->2AlCl3+3H2O
AlCl3+3NaOH->Al(OH)3+3NaCl
2Al(OH)3+3K2SO4->Al2(SO4)3+6KOH
Al2(SO4)3+6KOH->2Al(OH)3+3K2SO4
