Calcium carbonate is made of the elements calcium, carbon, and oxygen.
Calcium phosphate and calcium carbonate are found in bones .
Limestone is primarily composed of calcium carbonate. However, calcium sulfate is not typically found in limestone; it is a separate mineral known as gypsum.
A stalactite is made of mineral deposits, typically calcium carbonate, that accumulate as water drips from the ceiling of a cave. Over time, these deposits form a cone-shaped structure that hangs down from the cave ceiling.
Calcium carbonate is the compound made from the elements oxygen, calcium, and carbon. It is commonly found in rocks, shells, and pearls.
