Question

below 1000K, coke can reduce.... A)Ag2O B)MgO C)Al2O3 D)ZnO

Answer 1

Hey dear,

● Answer -
Zinc oxide (ZnO)

● Coke as reducing agent -
- Coke (C) is good reducing agent as it combines with oxygen to form gaseous non-metallic oxides mostly at high temperature.
- The metal oxide is mixed with coke and heated in a huge furnace.
- Coke reduces metal oxide to metals
E.g. ZnO + C --> Zn + CO
- This method is used for extraction of zinc, iron, lead & copper.

Hope this helps you...
