Answer 1

4Al+3O2==2Al2O3 
Al2O3+6HCl==2AlCl3+3H2O 
AlCl3+3NaOH==Al(OH)3+3NaCl 
Al2O3+3H2SO4=Al2(So4)3+3H2O
Al(OH)3+3HNO3=Al(NO3)3+3H2O
NaAlO2 +HCl = NaCl + Al(OH)2

Answer 2

4Al+ 3O2=2Al2O3
Al2O3 +6HCl = 2AlCl3 + 3H2O
AlCl3 +3NaOH=Al(OH)3 +3NaCl
2Al(OH)3 + 3H2SO4 =Al2(SO4)3 + 6H2O
Al2(SO4)3 + 6HNO3 = 2Al(NO3)3 + 3 H2SO4
Al(OH)3 + NaOH = NaAlO2 + 2H2O

Answer 3

4Al+3O2==2Al2O3
Al2O3+6HCl==2AlCl3+3H2O
AlCl3+3NaOH==Al(OH)3+3NaCl
Al2O3+3H2SO4=Al2(So4)3+3H2O
Al(OH)3+3HNO3=Al(NO3)3+3H2O
NaAlO2 +HCl = NaCl + Al(OH)2

Answer 4

4Al+ 3O2=2Al2O3
Al2O3 +6HCl = 2AlCl3 + 3H2O
AlCl3 +3NaOH=Al(OH)3 +3NaCl
2Al(OH)3 + 3H2SO4 =Al2(SO4)3 + 6H2O
Al2(SO4)3 + 6HNO3 = 2Al(NO3)3 + 3 H2SO4
Al(OH)3 + NaOH = NaAlO2 + 2H2O
