Question

Philosopher's wool on heating with $BaO$ at ${1100}^{\circ }C$ gives :

• A. $BaCd{O}_2$
• B. $Ba+Zn{O}_2$
• C. $Ba{O}_2+Zn$
• D. $BaZn{O}_2$

Answer 1

The correct option is D $BaZn{O}_2$

$ZnO$ is known as Philosopher's wool. The reaction of $ZnO$ with $BaO$ at ${1100}^{o}C$ gives $BaZn{O}_2$.

The reaction is as follows:
$ZnO+BaO\to BaZn{O}_2$
Option D is correct.
