Question

Philosopher's wool on heating with bao at 1100oc produces

Answer 1

Hi there.

Answer ⇒ BaZnO₂  (Barium Zincate)

Explanation ⇒ 
Chemical Formula of the Philosopher wool is ZnO (Zinc Oxide).
We know that ZnO (or Zinc Oxide) is the Amphoteric Oxide (i.e., It reacts with the both Acids and the bases)

Chemical Equation For the above is ⇒

ZnO + BaO -------1100 °C-----→ BaZnO₂ (Barium Zincate).

This Reaction is only possible when the temperature is around 1100 °C.

 In this Reaction, When Philosophers wool (or Zinc oxide) is heated with the Barium Oxide at the temperature around 1100 °C it produces the Barium Zincate.


Hope it helps.

Answer 2

Philosopher's wool is ZnO. It is an amphoteric acid (which reacts with both acids and bases).

Philosopher's wool on heating with BaO at 1100°c produces Barium Zincate (BaZn$O_2$)
 Chemical Reaction :

Bao + Zno    -----------(1100°C)--------->  BaZn$O_{2}$

Hope it helps
