Answer» Explanation:
Smithsonite = Zinc Oxide + Carbon Dioxide
Smithsonite - ZnCO3 ZnCO3 -Zinc Carbonate Density- 3.5 g/cm3 Molecular Weight/ Molar Mass -125.38 g/mol Stability -Stable but INCOMPATIBLE with acids Boiling POINT- 333.6 °C at 760 mmHg Melting Point- ~1970 °C Chemical Formula -CO3Zn ZnCO3————> ZnO+ CO2- decomposition reaction |
