yes
No,, it is actually calcium sulfate. Calcium bicarbonate is not stable as a solid.
The common name of Calcium carbonate may be Chalk, but chemically that's not true, if it is the blackboard writing chalk. This chalk is actually Calcium sulfate, which is mistaken as Calcium carbonate, as its manufacturing process uses Calcium carbonate.So, I think the common name for chalk should be Limestone, which is the most common mineral form of this compound.
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.
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.
Calcium carbonate is commonly known as chalk, limestone, or marble.

Calcium sulfate is used as water absorbent.
Calcium sulfate is a chemical compound that consists of calcium, sulfur, and oxygen. It is commonly found in nature as the mineral gypsum. Calcium sulfate is used in a variety of applications, such as in construction materials, food additives, and as a soil conditioner in agriculture.

No. Blackboard chalk is calcium sulfate, also known as gypsum. Cliff chalk is calcium carbonate, also known as calcite or limestone.
Calcium carbonate is commonly known as chalk, limestone, or marble.
Rock gypsum is a sedimentary rock. These rocks can be transparent or opaque. Examples could be chalk and chalk boards.
Chalk is comprised of calcium sulfate. Specifically, it comes in the form CaSO4.2H2O, which is the dihydrate often known as gypsum.
Chalk is a soft, white, porous sedimentary rock, a form of limestone composed of the mineral calcite which is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). It forms under relatively deep marine conditions from the gradual accumulation of minute calcite plates (coccoliths) shed from micro-organisms. Chalk can also refer to other compounds including magnesium silicate and calcium sulfate.
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.
