They are:
Pick whichever 4 you want.
Carbon monoxide is a pure substance, as it is made up of molecules that are all identical (one carbon atom and one oxygen atom). It does not contain different types of molecules mixed together.
Coke is a pure substance. It is primarily composed of carbon atoms and does not contain any other types of atoms or molecules.
Pure substance; it is one form of pure carbon.
pure carbon is coal, also diamonds are coal that was under a lot of pressure. so both diamonds and coal are pure carbon.
Carbon monoxide is a molecular compound made up of one carbon atom and one oxygen atom. It is not an element because it is composed of different types of atoms. However, it can be considered a pure substance because it consists of only carbon and oxygen atoms combined in a fixed ratio.
Carbon monoxide is a pure substance, as it is made up of molecules that are all identical (one carbon atom and one oxygen atom). It does not contain different types of molecules mixed together.
An element is a pure substance with only one type of atom. Any pure substance - oxygen, carbon, aluminium. It cannot have two different types of atoms, like carbon dioxide, which has carbon atoms and oxygen atoms.
Yes, carbon black is pure carbon.
yes, a diamond is a crystalline form of pure carbon, there for making it a pure substance.
Coke is a pure substance. It is primarily composed of carbon atoms and does not contain any other types of atoms or molecules.
Pure substance; it is one form of pure carbon.
Yes, it is pure carbon if it is flawless.
No, it is not a mixture at all, it is a pure substance as the word "pure" might imply.
Carbon is a pure substance with the chemical symbol "C"
pure carbon is coal, also diamonds are coal that was under a lot of pressure. so both diamonds and coal are pure carbon.

Carbon. Coal has a few different types and grades, but hard anthracite coal is almost pure carbon. Same as graphite, soot and diamonds.
