A change in color would indicate some sort of reaction.  xenon is a noble gas and is nonreactive, so no.

You can't balance it because you don't know what it yields.\n\n\nP.S. This needs to be in the chemistry category. You really must not know much about chemistry and physics.

It has to do with light scattering by molecules in the atmosphere...this question is asked almost every 12 hours, check the old questions to have a good answer

I studied that in physical science... which was about 5 years ago. So, the answer is: "hell if I know"! Ask me something about English, literature, or Spanish... then maybe I can be of some help :p\n\nthanks for the points anyway :)

Niuchemist is mostly right and deserves the vote, but there is one correction I would make-heavier molecules don't necessarily have less "kinetic energy", they move more slowly-it is the speed of movement that is the critical thing, not the kinetic energy, which is a product of speed *and* mass.

I have often wondered this myself.  \n\nBy the way, your answer to my Homework question was correct! Thank you. It was a big help.  I am taking an online test that grades each question as I go.  Thanks again.

Here it is again folks, our educational system failure on parade!  This is 4th grade science. 24 hours is the answer.  Please donate your tax money to me rather than your local school system.

Come on now. Do your own homework. Wouldn't it be more efficient use of your time on the computer to search for "recent scientific article"\nTry americanscientist.org or .com or .edu
