Answer:
See below ~
Step-by-step explanation:
Question 1
- Fe₂O₃ undergoes reduction to form 2Fe
- 3CO undergoes oxidation to form 3CO₂
- This is an oxidation-reduction reaction, or a redox reaction
Question 2
- Here O₂ is added to Fe to form Fe₂O₃
- Hence, the addition of oxygen means it is oxidation
