NaNO3 and CaCO3 are _.
Correct answer: C. Isomorphous
- A. Allotropes
- B. Amorphous
- C. Isomorphous
- D. Polymorphous
Explanation
Polymorphous refers to substances that can exist in multiple crystal structures. NaNO3 and CaCO3 are polymorphous because they can each exist in different crystal forms. For example, NaNO3 can exist in both an anhydrous form (sodium nitrate) and a hydrated form (sodium nitrate decahydrate). Similarly, CaCO3 can exist in different crystalline forms such as calcite and aragonite.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
