Question

What is memorable about calcite, a carbonate?

a. Its ability to conduct electricity
b. Its use as a common building material
c. Its double refraction property when in crystalline form
d. Its high radioactivity

Answer 1

Calcite is memorable for its double refraction property when in crystalline form.

Step-by-step explanation:

Calcite, a form of calcium carbonate (CaCO3), is known for its double refraction property when in crystalline form. Double refraction is the phenomenon where light passing through a crystal splits into two rays with different velocities. When a transparent crystal of calcite is placed over a page, we can observe two images of the letters, which is a unique characteristic of calcite.
