Group of students placed each compound in a small bowl and stuck each end of a battery powered circuit in the compound

Compound CO2 (s) : Not conductive

Compound KCl (s): Not conductive

Compound CaO(s): Not conductive

Based on the data, Can they determine Which compound is ionic and which is covalent?

• No, as ionic compounds are only conductive in water solution

• Yes, All these compounds are ionic since they are not conductive

• No, as covalent compounds are only conductive in a water solution

• Yes, as all of these compoundsare covalent since they are not conductive
