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

CaS= 20)2)8)8)2 . S= 16 . )2)8)6 needs 2 more to complete outershell on Periodic Table
Ionic wants to give away--------------------- non metal wants to accepts gives away 2-------------------------------- accepts 2 leaving behind18 electrons --------------- and giving 18 electrons to complete its outer shell 20-18= +2 . 18-16= -2
+2 minus -2=0 Answer . CaS
I hope this is correct and not Ca2+S2

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.
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 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.
Is making chalk dust a chemical change?
No, it is a physical, not chemical change.

What is the chemical name for sand paper?
There isn't one specific chemical name for sand paper. It isn't just one chemical.
What is the chemical name offor chalk?
CaCO3 ... Calcium Carbonate
Explain why blackboards are not scratched by chalk but are scratched by the sand embedded in the chalk?
The hardness of sand is higher.
Explain Why blackboards are not scratched by chalk but by the sand embedded in the chalk?
Blackboards are not scratched by chalk because chalk is softer than the material from which the blackboard is constructed. Sand scratches blackboards because it is harder than the material from which a blackboard is made.
Limestone is the chemical content of chalk?
The chemical formula of chalk or limestone is calcium carbonate (CaCO3).
What is the chemical name for sand?
silicon dioxide (SiO2 )
How do you separate a mixture of sand salt chalk dust and amp iron filings.?
First remove iron filings with a magnet. That leaves sand, salt and chalk dust. Add water which dissolves the salt, and filter leaving the sand and chalk dust on the filter paper. Put that back in water and add acid to dissolve the chalk dust (CaCO3) leaving the sand as a solid. Filter to obtain the sand. The chalk dust will now be in the acid as CO2 and H2O and the Ca salt of the acid.
How do you separate sand and chalk?
Sand and chalk can be separated through the centrifugal process. A centrifuge makes high speed cycles and the materials of different densities will be separated.
