Yes "blackboard chalk", it is formed from the microscopic pieces of calcite (coccoliths) from sea micro-organisms.
Soem other compounds are sometimes called chalk- e.g. "tailors chalk a very hard chalk used to mark cloth is often made from compressed "talc" a silicate mineral.

Yes. CaCO3 .
Chalk or limestone: chemical formula is CaCO3 - calcium carbonate.
But the physical and mineralogical properties are different.

Calcium bicarbonate formula?
The chemical formula (not symbol) of calcium bicarbonate is Ca(HCO3)2.
Compound element of chalk?
Chalk is a compound, chemically it is calcium carbonate, CaCO3, and has the elements calcium, carbon and oxygen
What are the elements present in chalk?
Chalk is predominantly calcium carbonate. Therefore, its elements are calcium, carbon, and oxygen.
Is limestone a solution?
No it is not. Limestone itself is not a solution. Limestone is a rock which is primarily calcium carbonate as are marble and chalk. Calcium carbonate will react with water if the water contains dissolved Carbon Dioxide (forming a mild carbonic acid) resulting in Calcium Bicarbonate which is soluble and does form solution in water.
What is a balanced equation for the decomposition of the solid calcium bicarbonate?
I don't know the equation but i have heard that down in certain depths calcium bicarbonate can be decomposed. However if it helps the equation to make calcuim bicarbonate is: Carbon dioxide + calcium carbonate + water Leads to Calcium Bicarbonate best i could do, I've been researching for a phytoplankton that decomposes calcium bicarbonate, that's how i found this and thought i should help contribute any of my knowledge, Kimo,
