Answer 1

because Hydrogen is below aluminium in the activity series, hence unable to reduce Al2O3.

hope it help.

mark me brainliest.

Answer 2

Answer:

Aluminium oxide cannot be reduced by hydrogen even under very hot conditions because Al is more reactive than H.

While other oxides can be reduced by hydrogen as they are below hydrogen in the metal reactivity series.
