Answer 2

Answer:

• 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 also is used as an antacid to relieve heartburn, acid indigestion, and upset stomach.
• Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide.
• Calcium carbonate (CaCO₃) is insoluble, so it is a solid in water(precipitate).
• Calcium carbonate is composed of three elements which are of particular importance for all organic and inorganic material on our planet: carbon, oxygen and calcium.
• The main use of calcium carbonate is in the construction industry, either as a building material, or limestone aggregate for road building, as an ingredient of cement, or as the starting material for the preparation of builders' lime by burning in a kiln.
