The properties of several unknown solids were measured. Solid Melting point A >1000 °C B 850 °C C 750 °C D 150 °C Other properties does not conduct electricity conducts electricity in the liquid state, but not in the solid state conducts electricity in the solid state does not conduct electricity Classify the solids as ionic, molecular, metallic, or covalent. Note that covalent compounds are also known as covalent network solids or macromolecular solids.
