The symbol (cr) in a chemical formula indicates which phase?

Explanation:
Phase labeling in chemical formulas tells you what physical form the substance is in. The symbol (cr) designates a crystalline, meaning the solid has atoms arranged in an orderly, repeating pattern. This distinguishes a crystalline solid from other solid forms (like amorphous) and from liquids or gases, which use different designators such as (l) for liquid, (g) for gas, or (aq) for an aqueous solution. So (cr) specifically points to a solid that has a well-ordered crystal structure.
