chalk is an ionic compound. which is a property of all ionic compounds that makes chalk particularly useful for writing on a chalkboard?\no a high melting point\no hardness and brittleness\no inability to dissolve in water\no a multicolored appearance
Answer
Brief Explanations:
Ionic compounds like chalk are hard and brittle. This property allows them to leave marks on a chalk - board as small pieces break off during writing. High melting point is not related to writing on a chalkboard. Many ionic compounds dissolve in water, and chalk is usually white or light - colored, not multicolored.
Answer:
hardness and brittleness
