Question

question 11 1 pts calcium carbonate is generally insoluble in water because the____ that hold the ions together are significantly__ than the solvation forces. electrostatic forces, less dispersion forces, less electrostatic forces, greater dispersion forces, greater question 12 1 pts sodium chloride is soluble in water because the__ that hold the ions together are significantly____ than the solvation forces. dispersion forces, greater electrostatic forces, less dispersion forces, less electrostatic forces, greater

Explanation:

For Question 11, calcium carbonate is an ionic compound. Ions in ionic compounds are held together by electrostatic forces. Since it's insoluble in water, the electrostatic forces holding ions together are greater than solvation forces. For Question 12, sodium chloride is also an ionic compound. Its solubility in water implies that the electrostatic forces holding its ions together are less than the solvation forces.

Answer:

Question 11: C. electrostatic forces, greater
Question 12: B. electrostatic forces, less
