Calcium carbonate CaCO3
Ground calcium carbonate (CaCO3) which is known as "GCC" by papermakers according to the Mini-Encyclopedia of Papermaking (www4.ncsu/~hubbe/chlk.htm and . . . ~hubbe/gcc.htm). See also . . . ~hubbe/pcc.htm which discusses the creation and use of precipitated calcium carbonate which is chemically identical to GCC.
Calcium carbonate is a common chemical name for chalk.
Calcium carbonate
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.
The chemical name of precipitated chalk is calcium carbonate. It is a white, odorless powder that is commonly used in industries such as pharmaceuticals, food production, and in the manufacture of paper and plastics.
it is C4HO2
I would say it is a physical change the chalk is being reduced to a smaller size. It still remains chalk.
No, it is a physical, not chemical change.
