Chemically combined refers to the process of something being combined with something else via a chemical reaction. They cannot be physically split up, as they require another chemical reaction to separate them.
A "mixture" is a group of several chemicals that have been mixed together in such a way they can be easily separated, usually without altering the state of matter of any of the chemicals.
Iron filings and sulfur powder would be a mixture; you can separate the two with just a magnet. Similarly, sand and sulfur powder would be a mixture. Just put it in water; the sulfur will float and the sand will sink.
Being chemically combined means that two or more different elements are combined through chemical processes. They make new products known as compounds.
When two substances are chemically combined, one accepts an electron from the other or they share electrons. When substances are physically combined, no electrons are shared or exchanged.
Two or more elements chemically combined form a compound.
The components of a mixture are physically combined.
molecules
mixture [mec3usa] Hydrated calcium sulphate is one example. The water in the substance is not chemically combined with the salt (CaSO4).
they are chemically combined
It is chemically combined! :)
Compounds are formed when elements of matter are chemically combined.
Group of substances that are not chemically combined.
Compounds are formed when elements of matter are chemically combined.
Compounds are formed when elements of matter are chemically combined.
not necessarily. A molecule is multiple atoms combined chemically, but the atoms do not need to be of different elements. A compound is several elements combined chemically though.
it depends on wht compound it its
Never it is physically combined.
Two or more elements chemically combined form a compound.
chemically combined elemets
Being chemically combined means that two or more different elements are combined through chemical processes. They make new products known as compounds.
The best way to find out if something is chemically combined is if you can take it apart. Try filtering it, and if you can't, it's not combined. it's just a element.
