Answer:
Calcium is homogeneous Three
percent of Earth's crust is made
of calcium
→ Minerals
Glycerin is a viscous liquid
at room temperature. → Non mineral
Emerald is hard and does not
decay. Its chemical formula is
Be₃Al₂SiO₆ → Minerals
Chlorophyll is produced in plants
during photosynthesis → Non minerals
Explanation:
Minerals are natural occurring crystalline substances that has a definite chemical formula . Minerals are usually solid in nature and are inorganic . Minerals contains no plant or animals.
Calcium is homogeneous because it contains only 1 substance. Calcium is regarded as a mineral because it is natural occurring and has a definite chemical formula and solid. The earth crust contains abundant of calcium.
Glycerin is not a solid . The source is from plant which makes it organic. Glycerin is a non mineral because it is liquid and organic in nature.
Emerald is a mineral . Emerald has a definite chemical formula and it is natural occurring , crystalline ,solid and inorganic in nature.
Chlorophyll is a substance produce in plants during photosynthesis . chlorophyll is organic because it is produce in plants . Therefore chlorophyll is not a mineral.
