Question
Which of the following statements for the given chemical
reaction is true? Fe2O3 + 2Al =  Al2O3 + 2FeSolution
Aluminum (Al) undergoes oxidation reactions that increase its oxidation number from zero to three while also introducing oxygen into the mix. Fe2O3 acts as an oxidising agent. Due to the removal of oxygen from Fe2O3 and the addition of Al, Fe2O3 is reduced to Fe. Aluminum (Al) thus serves as the reducing agent.
