is the following a compound? (a compound is when two or more elements are chemically combined)
when 2 samples of some elements are put in a jar together? is it combining it chemically? i am sort of confused. CALLING ALL SCIENTISTS!

Nope, it's a mixture.
Unless when you combine them all, there is reaction. If reaction occurs, then it changed to a compound, and to break them down, need chemical reaction.
Hope it helps!

If you put some powdered yellow sulfur, called flowers of sulfur, into a jar with iron filings, that is a mixture, not a compound. If you wave a magnet over the mixture, you could pick up the iron filings from the sulfur mixture. However, if you put that mixture into a spoon and heat the spoon over a gas flame, the sulfur would combine chemically with the iron to produce a new compound, iron sulfide. You could not then separate the sulfur from the iron with any magnet.

no it isnt, unless they react with each other.
i.e. i could put hydrogen and oxygen in a jar together, but that doesn't give me water.
however, if they react, i.e sodium and chlorine, it would be a compound known as table salt.
