The proper chemical composition of pure salt is NaCl aka Sodium Chloride.
Chemically, it is 60.663% elemental chlorine (Cl) and 39.337% sodium (Na).
Rock salt typically ranges between 95% and 99% NaCl, and mechanically evaporated salt and solar salt normally exceed 99% NaCl. Evaporated salt made with purified brine has the highest purity, in some cases 99.99% NaCl.
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
Atom
Yes
yes it can
A definite chemical composition
Colon is an organ not a compound with definite composition.
Yes
This law hasn't a chemical equation !
A definite chemical composition
it means a naturally-occaring, inorganic solid that has a crystal structure and a definite chemical composition
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
