carbon monoxide is.....?

Question

1. an atom,an element and a mixture.
2.an atom,an element and a pure substance.
3.a molecule, a compound and a mixture.
4.an atom, a compound and a mixture.
5.a molecule,element and a pure substance.
6.a molecule, a compound and a pure substance.

Answer 1

Not an atom, since the unit has two atoms (Carbon and Oxygen).
Not an element, for the same reason.
Not a mixture, it's a pure substance.
So, it's #6.

Answer 2

It is 6. When you see a chemical formula with more than one symbol in it, or in this case a name with multiple elements in it, that can't be an atom, because it's actually a group of atoms by definition. For the same reason, it's not an element, because it contains two separate elements. So it must be a compound. And a compound is always a pure substance, as are elements.

Answer 3

6

Answer 4

6

Answer 5

6

clearly carbon monoxide is a molecule

certainly it is a compound

and because it isn't mixed with any other compound, it is a pure substance

It doesn't seem to me that you are getting the hang of the vocabulary and principles being taught here. It might be time to read the chapter, instead of just transcribing Y!Answers into some homework that you don't understand and will come back to haunt you on some test

good luck
chemistry is good stuff
you have to understand it to use it right

Answer 6

6. a molecule, a compund and a pure substance.

Answer 7

I had honors chemistry and its definitely 6.

Answer 8

6, but you should do your own homework

Answer 9

its number six
