We’re being asked to identify which element is oxidized in the given reaction:


Fe2O3 + 3CO → 2Fe + 3CO2


To do so, we need to identify the change in oxidation state for each element in the reaction. 

Recall the mnemonic for redox reactions:

Loss Electrons  Oxidation  Reducing Agent

Gain Electrons  Reduction  Oxidizing Agent


This means the element that gains electrons/reduced is the oxidizing agent while the element that loses electrons/oxidized is the reducing agent
