Oxidizing agent: Cr2O3 (Cr is reduced from +3 to 0)
Reducing agent: Al(s) (Al is oxidized from 0 to +3)
Explanation: Cr in Cr2O3 goes from +3 → 0 (gains electrons), so Cr2O3 accepts electrons (oxidizing agent). Al goes from 0 → +3 (loses electrons), so Al donates electrons (reducing agent).
Reducing agent: Al(s) (Al is oxidized from 0 to +3)
Explanation: Cr in Cr2O3 goes from +3 → 0 (gains electrons), so Cr2O3 accepts electrons (oxidizing agent). Al goes from 0 → +3 (loses electrons), so Al donates electrons (reducing agent).
