4Al + 3O2 = 2Al2O3
Al2O3 + 3H2 = 2Al + 3H2O
2Al + 6H2O = 2Al(OH)3 + 3H2
Al(OH)3 + NaOH = Na[Al(OH)4]
Na[Al(OH)4] + 4HCl = NaCl + 4H2O + AlCl3
AlCl3 + 3KOH = Al(OH)3 + 3KCl
Al(OH)3 + 3HNO3 = Al(NO3)3 + 3H2O

Verified answer
4Al + 3O2 = 2Al2O3
Al2O3 + 3H2 = 2Al + 3H2O
2Al + 6H2O = 2Al(OH)3 + 3H2
Al(OH)3 + NaOH = Na[Al(OH)4]
Na[Al(OH)4] + 4HCl = NaCl + 4H2O + AlCl3
AlCl3 + 3KOH = Al(OH)3 + 3KCl
Al(OH)3 + 3HNO3 = Al(NO3)3 + 3H2O
