• # question_answer Philosopher's wool on heating with $BaO$ at $1100{{\,}^{o}}C$ produces A) $BaZn{{O}_{2}}$               B) $BaCd{{O}_{2}}$  C)      $Ba{{O}_{2}}+Zn$D)      $Ba+Zn{{O}_{2}}$

Philosopher's wool is zinc oxide, which on heating with $BaO$ at $1100{}^\circ C$ produces $BaZn{{O}_{2}}.$ $ZnO+BaO\xrightarrow{1100{{\,}^{o}}C}BaZn{{O}_{2}}$ Hence, the correct option is (a).
