What is the luster of chalk?
Chalk has a dull, matte luster. Chalk is a soft, white, porous sedimentary rock, composed of the mineral calcite. Because chalk is porous it can hold a large volume of ground water, providing a natural reservoir that releases water slowly through dry seasons.

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).
Which property of chalk is responsible for absorption of water in it?
It is very porous, meaning it has lots of very little holes in it. So the water gets in.
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.
