I will upload a picture for these questions.
7.) Which best represents a solid element?
8.) Which best represents a homogeneous mixture of an element and a compound?
9.) Which best represents a gaseous compound?
10.)Which best represents a heterogeneous mixture of two elements?

Without a picture, a solid will mainly be something where there is a high degree of order. Molecules are arranged in an orderly fashion.

I thinks its B
Now for the gaseous compound: think about it this way, gases are free of any intermolecular forces so they will be able to move around independently which one suits this description
8 confuses me
Well so do the rest
Would it be A?
9 is A but for the reasons i stated earlier about gases, can you picture why this would be true?
For your reference
Homogeneous = means a mixture that's uniform
Heterogeneous means a mixture that's not uniform
Because they move more freely than the other diagrams?
The one stating an element and a compound heterogenous I believe would be E because the single atom is more likely to be the element.
Sorry I think 9 is C because it's a compound but the reasons still hold true
Yes you're correct, I'm not sure about 10 I'm debating whether it should be D since you clearly have two different types of atoms.
So 9 is A and they confuse me. I have two more questions for this but didn't post them
I want to say C because a compound contains more than one element, you see how those two atoms are different yet they are bonded to each other?
I thought it was A originally I guess that would be an element.
Hope this has helped you
