Cas 1305-78-8,Calcium oxide | lookchem

Calcium oxide (CaO, CAS Reg. No. 1305-78-8) is also known as lime, quick lime, burnt lime, or calx. Lime does not occur naturally since it reacts so readily with water (to form hydrated lime) and carbon dioxide (to form limestone). It is produced from calcium

What is Chemical Weathering? - WorldAtlas

First, carbon-dioxide reacts with water to form carbonic acid. Next, carbonic acid reacts with minerals in rocks to produce carbonates or bicarbonates. Carbonation of rocks containing calcium carbonate (limestone) is a common process of chemical weathering which leads to the formation of calcium bicarbonate that is highly soluble in water.
