Question

Zinc oxide can be reduced to metal by heating with carbon but not cr2o3

Answer 1

yes because carbon(coke ) is the best substance preferred for reducing it as a common reducing agent and its efficiency for oxygen is much more than cr2o3

Answer 2

Hey buddy,

◆ Reduction of zinc oxide (ZnO) -
Reduction of an oxide by a substance depends on reducing ability of the substance.

As Carbon(C) is more reductive than chromium oxide(Cr2O3), it has more affinity towards oxygen.

Therefore, zinc oxide can reduced to metal by heating with carbon but not chromium oxide.

Hope it helps...
