Question

The metal oxide which cannot be reduced to metal by carbon is (a) Al2O3

Answer 1

All the oxides ore can be reduced by Carbon if temperature is sufficiently highbecause carbon act as good reducing agent at hightemperature.Carbon reduction is done for many metallic oxides like ZnO PbO SnO2 etc but in case of Al2O3 Carbon reduction is not done because it will require very high temp as Al2O3 is very ...
