the chemical name for limestone is Calcium Carbonate
Chemical formula is CaCo3
Calcium carbonate, CaCO3.
calcium carbonate
Chalk.
No. It is a physical or mechanical change.
No. Dolomite is formed by the replacement of Calcium in the mineral calcite by Magnesium, giving the chemical formula (Ca,Mg)CaCO3. Rocks formed largely of calcite are called limestones, and those which show extensive Magnesium substitution in calcite are called Dolomitic limestones.
Certain limestones, and gypsum.
organic sedimentary rocks such as coal and some limestones which form from the accumulation of plant or animal debris.
Limestones are chemical sedimentary rocks, also called carbonate rock as it is made up of the carbonate radical CO3, hense Calcite CaCO3 Limestone. Although some limestones form by inorganic chemical precipitation most limestones are biochemical because they are mostly composed by organisms. Examples of limestone include Coquina composed almost entirely of fragmented seashells and Chalk, composed largely of microscopic shells.

This would usually be caused by the dissolution of soluble rocks such as limestones. Dissolution is a chemical weathering process.
The limestone consists mainly of calcium carbonate: CaCO3 ,Calcite. Like most other sedimentary rocks, limestones are composed of grains, however, around 80-90% of limestone grains are skeletal fragments of marine organisms such as coral or foraminifera. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Some limestones do not consist of grains at all and are formed completely by the chemical precipitation of calcite or aragonite. (i.e. travertine.)

Chemical Weathering.. because as rocks exposed to acid rains like limestones, it slowly dissolve and change into a new form
