there are many types of sand, its constituents vary dependent on where it is found due to the difference in rock types in different areas. however the most common constituent of sand is silicon dioxide (sio2) otherwise known as silica
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.
The chemical symbol for chalk is CaCO3, which represents the compound calcium carbonate.
No, it is a physical, not chemical change.
Breaking a lump of chalk into powder is a physical change, not a chemical reaction. The chemical composition of the chalk remains the same before and after breaking it into powder.

CaCO3 ... Calcium Carbonate
There isn't one specific chemical name for sand paper. It isn't just one chemical.
The hardness of sand is higher.
Limestone and chalk, together with marble and egg shells, are both impure form of calcium carbonate. The impurites are different in each substance, but only in small/trace amounts.
Sand and chalk are not a homogeneous mixture because they do not have a uniform composition, meaning their components are visibly distinguishable from each other. Sand consists of larger particles like silica, while chalk is composed of calcium carbonate.
One common method to separate sand and chalk is to use the method of sedimentation. By placing the mixture in water, the chalk will float while the sand will sink to the bottom. The layers can then be separated using filtration.
