Identify the reducing agent: Fe₂O₃ + 3CO -------- 2Fe + 3CO₂. Also explain it.

Carbon monoxide(3CO) is the reducing agent. Reducing agent is an element or a compound that loses electrons. In other words, it is said to be oxidized. In this reaction, 3CO gains oxygen (while reacting with Fe2O3) and becomes 3CO2. So, here 3CO gets oxidized and therefore, 3CO is the reducing agent. Hope it helps.... Good Luck!!!!
