उत्तर
An oxidizing agent is one that oxidizes other substances (by removing hydrogen or adding oxygen) while also reducing itself.
`"CuO" + "H"_2 -> "Cu" + "H"_2"O"`
Cupric oxide (CuO) acts as an oxidizing agent in the aforementioned reaction, converting hydrogen (H2) into water (H2O) and copper (Cu).
