Philosopher's wool when heated with BaO at 1100°C gives the compound : — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Philosopher's wool is the traditional alchemical name for zinc oxide (ZnO). Step 2: When zinc oxide (ZnO) is heated at a high temperature (around 1100°C) with barium oxide (BaO), they undergo a solid-state reaction. Step 3: The reaction is BaO + ZnO -> BaZnO2, yielding barium zincate. Thus, the compound formed is BaZnO2, corresponding to option (d).
