Question

determine whether the material is a mineral or a non-mineral based on the description.
mineral non-mineral

description	mineral or non-mineral?
glycerin is a viscous liquid at room temperature.
emerald is hard and does not decay. its chemical formula is $\ce{be_{3}al_{2}sio_{6}}$.
chlorophyll is produced in plants during photosynthesis.

Explanation:

Step1: Recall mineral definition

A mineral is a naturally occurring, inorganic, solid, crystalline substance with a definite chemical composition.

Step2: Analyze Calcium

Calcium (element, inorganic, solid, naturally in Earth's crust) → Mineral.

Step3: Analyze Glycerin

Glycerin (organic, liquid, not naturally crystalline mineral) → Non - Mineral.

Step4: Analyze Emerald

Emerald (naturally occurring, inorganic, solid, crystalline, definite formula $\ce{Be3Al2SiO6}$) → Mineral.

Step5: Analyze Chlorophyll

Chlorophyll (organic, produced by plants, not a mineral) → Non - Mineral.

Answer:
