Answer 1

Bài 5 :

( 1 ) \(4Al+3O_2\rightarrow2Al_2O_3\)

( 2 ) \(Al_2O_3+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+3H_2O\)

( 3 ) \(Al_2\left(SO_4\right)_3+8NaOH\rightarrow2NaAlO_2+3Na_2SO_4+4H_2O\)

( 4 ) \(NaAlO_2+HCl+H_2O\rightarrow Al\left(OH\right)_3+NaCl\)

( 5 ) \(2Al\left(OH\right)_3\rightarrow Al_2O_3+3H_2O\)

( 6 ) \(2Al_2O_3\rightarrow4Al+3O_2\)

( 7 ) \(2Al+2NaOH+2H_2O\rightarrow2NaAlO_3+3H_2\)

( 9 ) \(2NaHSO_4+2KOH\rightarrow Na_2SO_4+K_2SO_4+H_2O\)
