CaCO3--Calcium carbonate--calcium, carbon, oxygen.
I thought the answer was here. That's why I clicked it. Aren't these answers?
Limestone is calcium carbonate, CaCO3.
Mostly Calcium carbonate = CaCO3
calcite

Calcite and aragonite have similar chemical compositions as limestone. Vaterite also has a similar composition, but is it a less common mineral.
Fossiliferous limestone has larger fossils in the rock and is of biochemical composition where as the oolitic limestone doesn't have any fossils and has a chemical composition. The Oolitic limestone has spherical grains that resemble miniature pearls (they are called ooliths or ooids). Both do effervesce in diluted HCL(acid)
Yes, crushing limestone is a physical change. This is because the chemical composition of limestone remains unchanged during the process of crushing. The size and shape of the limestone particles may change, but the chemical makeup remains the same.
What are some uses of chemical limestone
The most common chemical sedimentary rock is limestone.
Calcite and aragonite have similar chemical compositions as limestone. Vaterite also has a similar composition, but is it a less common mineral.
The colours of limestones vary depending on their chemical composition. An iron content to limestone can give a tinge of iron oxide (rust) colour. The exact chemical composition will depend on the origin and geological process resulting that stone.

Limestone is a sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate (CaCO3).
Yes, crushing limestone is a physical change. This is because the chemical composition of limestone remains unchanged during the process of crushing. The size and shape of the limestone particles may change, but the chemical makeup remains the same.
It depends on their size and chemical composition. Fossils closely akin to the limestone matrix in composition would need to be manually removed by use of dental tools, scrapers, or electric Dremel type tools. If the fossil has been replaced by silica, it could be removed by the application of acid to remove the limestone that surrounds it.
Yes limestone is a chemical rock
What are some uses of chemical limestone
Chemical limestone can form when calcite is dissolved.
The most common chemical sedimentary rock is limestone.
