The Limestone Chemistry Cycle

Limestone (calcium carbonate) is a very important natural chemical material. It is a sedimentary rock, made from the shells of sea creatures which died millions of years ago. Limestone (CaCO 3) has lots of uses such as an abrasive for toothpaste, a calcium additive in bread making, filler in plastics used in floor tiles, and a building material.
