calcium cation = Ca2+
carbonate ion = CO32-
the charges should cancel and you have the correct formula

What is the chemical formula of chalk?
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.
What is the difference between Chalk and Gypsum?
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.
What is the chemical composition of chalk?
Chalk is mostly calcium carbonate, with the formula CaCo3. It is formed from the crushed bodies of tiny sea creatures, which over eons collected as sediment on sea floors, was uplifted, then worn away by erosion and weathering. Chemically speaking, calcium carbonate is the union of the alkaline earth metal calcium and the polyatomic carbonate ion.
Where is the carbon in chalk?
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).
Is chalk is composed of calcium carbonate?
Chalk is simply another form of Calcium Carbonate(CaCO3)

Limestone is the chemical content of chalk?
The chemical formula of chalk or limestone is calcium carbonate (CaCO3).

What is the chemical name offor chalk?
CaCO3 ... Calcium Carbonate
Is chalk the same form of limestone?
The chemical formula is identical (CaCO3, calcium carbonate) but the physical and mineralogical properties are different.
How do you know if chalk contains calcium carbonate?
Through chemical analysis of a piece of chalk!
What kind of mixture is chalk?
Chalk is not a mixture it is a chemical compound called Calcium carbonate.
What is the name of the formula CaCO3?
The name of the chemical formula CaCO3 is calcium carbonate. Calcium carbonate is commonly found in rocks and is created when ions in hard water react with carbonate ions to create limescale. The hardness of water is measures in ppm CaCO3.
