Question
CaCO3 is the chemical formula for
- Fiber
- Proteins
- Marble
- Common salt
Hint:
Marble is composed primarily of the mineral calcite.
The correct answer is: Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated (layered), although there are exceptions. In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
CaCO3 is the chemical formula for marble.
