Caco3 (Chemical formula)

Calcium carbonate, with the chemical formula CaCO₃, is a common natural compound found in materials like limestone, marble, and chalk. It consists of calcium, carbon, and oxygen atoms arranged in a crystal structure. It is widely used in construction (as a building material), in the manufacturing of cement and paper, and as a dietary supplement to provide calcium. When heated, calcium carbonate decomposes into calcium oxide and carbon dioxide gas. Its versatility and abundance make it an important substance in many industries and ecological systems.
