(C.7D)

Data Table: sample A = low boiling pt, not electrical conductor, not soluble in water; Sample B = high boiling pt, conducts electricity, dissolves in water

Carl and Sally designed an experiment to compare and contrast the properties of compounds. After designing their experiment, Carl and Sally tabulated the data in the table seen here. Based on their data, compound B most likely represents

Question 4 options:

A covalent compound


An ionic compound


A metallic compound

Answer 3

Based on the data provided, compound B most likely represents an ionic compound. Ionic compounds often have high boiling points, conduct electricity when dissolved in water (in the form of ions), and are soluble in water.
