b) \(Al_2O_3\rightarrow Al\rightarrow Al_2\left(SO_4\right)_3\rightarrow AlCl_3\rightarrow Al\left(OH\right)_3\rightarrow Al_2O_3\)

c) \(Al\rightarrow AlCl_3\rightarrow Al\left(OH\right)_3\rightarrow Al_2O_3\rightarrow Al_2\left(SO_4\right)_3\rightarrow AlCl_3\)

Answer 1

a)\(4Al+3O_2\underrightarrow{t^o}2Al_2O_3\)

   \(Al_2O_3+6HCl\rightarrow2AlCl_3+3H_2O\)

   \(2AlCl_3+3Ba\left(OH\right)_2\rightarrow2Al\left(OH\right)_3\downarrow+3BaCl_2\)

   \(2Al\left(OH\right)_3\underrightarrow{t^o}Al_2O_3+3H_2O\)

   \(2Al+3S\underrightarrow{t^o}Al_2S_3\)
