What is the chemical name for chalk and sand?

Answer 1

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

Answer 2

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

Answer 3

The chemical name for chalk is calcium carbonate (CaCO3) and the chemical name for sand is silicon dioxide (SiO2).

Answer 4

Answer 8

Silicon dioxide is the scientific name and the formula is SiO2.

Answer 9

Chalk is calcium carbonate - CaCO3.
Sand is of very different origin and composition (frequently SiO2).

Answer 10

Silicon Di Oxide
