Best Answers

​ Calcium carbonate is the most common organic compoundand raw material found on the surface of Earth. It carries the chemical formula CaCO3. read more

Calcium carbonate is present on Earth in two major crystalline forms – the calcite and the aragonite forms. Carbonite occurs in various mineral forms on the surface of Earth like limestone, marble, chalk etc. read more

Calcium carbonate. Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which contains both of those minerals) and is the main component of pearls and the shells of marine organisms, snails, and eggs. read more

Calcium carbonate, or CaCO3, comprises more than 4% of the earth’s crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. read more

Alternatively through synthetic preparation, crude Calcium Oxide (CaO) is allowed to react with water to produce Calcium Hydroxide (Ca (OH) 2). When Carbondioxide gas is passed through this solution, it precipitates to form calcium carbonate. read more

Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous. read more

Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. read more
