优质解答：

(1) 2Al + 2NaOH + 2H2O === 2NaAlO2 + 3H2↑

(2) 4Al + 3O2 === 2Al2O3(条件:点燃)

[2Al + Fe2O3 === Al2O3 + 2Fe(条件:高温)]

(3) 2Al2O3 === 4Al + 3O2↑(条件:电解)

(4) 2Al + 3Cl2 === 2AlCl3(条件:点燃)

[2Al + 6HCl === 2AlCl3 + 3H2↑]

(5) Al2O3 + 2NaOH === 2NaAlO2 + H2O

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

(7) NaAlO2 + HCl + H2O === NaCl + Al(OH)3 ↓

(8) Al(OH)3 + NaOH === NaAlO2 + 2H2O

(9) 2Al(OH)3 === Al2O3 + 3H2O(条件:加热)

(10)Al(OH)3 + 3HCl === AlCl3 + 3H2O

(11)AlCl3 + 3NH3.H2O === Al(OH)3 ↓+ 3NH4Cl

[AlCl3 + 3NaOH === Al(OH)3 ↓ + 3NaCl]

(12) (12)NaAlO2 + 4HCl(过) === AlCl3 + NaCl + 2H2O
