Chalk is CaCO3.
The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
Chalk is CaCO3.
The chemical name for chalk is calcium carbonate.
(it is also called limestone)
The chemical name for chalk is Calcium carbonate.
True chalk (limestone) is calcium carbonate, CaCO3.
However, sidewalk chalk (gypsum) is calcium sulfate, CaSO4
caCO3 is the chemical formula. its limestone.

CACO 3
Gypsum is a very soft mineral made of calcium sulfate dihydrate, chemical formula CaSO4·2H2O. Chalk is soft, white, porous limestone composed calcium carbonate, chemical formula CaCO3.
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
CaCO3 is a chemical compound; it is the chemical formula of calcium carbonate (examples from nature are chalk and calcite).
it is C4HO2
I would say it is a physical change the chalk is being reduced to a smaller size. It still remains chalk.
The chemical formula of chalk or limestone is calcium carbonate (CaCO3).

CaCO3 is a chemical compound; it is the chemical formula of calcium carbonate (examples from nature are chalk and calcite).
The chemical formula is identical (CaCO3, calcium carbonate) but the physical and mineralogical properties are different.
it is C4HO2
Blackboard chalk contains no carbon, being composed mainly of gypsum, its chemical formula being CaSO4·2H2O.Neither does chalk, a soft, white, porous sedimentary rock, is a form of limestone composed of the mineral calcite, the most stable polymorph of calcium carbonate (CaCO3).
I would say it is a physical change the chalk is being reduced to a smaller size. It still remains chalk.
Through chemical analysis of a piece of chalk!
Chalk is not a mixture it is a chemical compound called Calcium carbonate.
The chemical name for precipitated chalk is calcium carbonate. It is a white, insoluble solid which is often used as an antacid.
