Na-Na2O-NaOH-Al(OH)3-AlBr3-Al2O3

Answer 1

4Na+O2=2Na2O
Na2O+H2O=2NaOH
AlCl3+3NaOH=Al(OH)3+3NaCl
Al(OH)3+3HBr=AlBr3+3H2O
AlBr3+3NaOH=Al(OH)3+3NaBr
2Al(OH)3=Al2O3+3H2O

Answer 2

4Na+O2=2Na2O
Na2O+H2O=2NaOH
AlCL3+3NaOH=AL(OH)3+3NaCL
Al(OH)3+3HBr=AlBr3+3H2O
ALBr3+3NaOH=3NaBr+Al(OH)3
2Al(OH)3=Al2O3+3H2O
