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 formula for chalk calcium and carbonate?
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
CaCO3 represents a chemical?
CaCO3 is a chemical compound; it is the chemical formula of calcium carbonate (examples from nature are chalk and calcite).
What is the chemical symbol for chalk?
it is C4HO2
When chalk is crushed is it a physical or chemical property?
I would say it is a physical change the chalk is being reduced to a smaller size. It still remains chalk.
Limestone is the chemical content of chalk?
The chemical formula of chalk or limestone is calcium carbonate (CaCO3).
What is the chemical formula of refractory chalk powder?
CaCO3

CaCO3 represents a chemical?
CaCO3 is a chemical compound; it is the chemical formula of calcium carbonate (examples from nature are chalk and calcite).
Is chalk the same form of limestone?
The chemical formula is identical (CaCO3, calcium carbonate) but the physical and mineralogical properties are different.
What is the chemical symbol for chalk?

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).
When chalk is crushed is it a physical or chemical property?
I would say it is a physical change the chalk is being reduced to a smaller size. It still remains chalk.
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.
Chemical name of precipitated chalk?
The chemical name for precipitated chalk is calcium carbonate. It is a white, insoluble solid which is often used as an antacid.
