Air is composed of nitrogen, oxygen, argon, carbon dioxide, and other gasses. How may air be best described?
a) a compound
b) a mixture
c) a solution
d) an alloy
e) an amalgam
Well, I have no idea what an amalgam is but I would say it is a mixture because the nuclei of the individual gasses aren't fused together, so you can't say it's a compound. I wouldn't depend on my answer, however...wait until a Jiskha expert answers.
An amalgam an alloy of mercury and another metal which may be a solid or a liquid depending upon the proportions of mercury used. The answer to the question is that air is a mixture.
