- a
- b✓
- c
- d
Reaction of with CuO:
Analysis:
- is a reducing agent — it reduces CuO
- Cu²⁺ in CuO is reduced to Cu(0) (metallic copper)
- is oxidised to
This is a classic reduction of metal oxide reaction. The black CuO is converted to reddish-brown metallic copper.
Why not Cu₂O? The reduction goes all the way to Cu(0) because H₂ is a strong enough reducing agent.
Answer: Option (2) — Cu(s)
