Can you take apart/separate a homogeneous mixture, like iced tea?
Yes.  By evaporating the water, the sugar will be remain.

What is the difference between heterogeneous and homogeneous mixture?
Homogeneous looks the same throughout and you can't take the mixture apart. Heterogeneous can be taken apart and is very easy to tell the parts of the mixture.

What does homogeneous mean?
When a mixture does mix evenly-appears too look the same throughout.

Give an example of a homogeneous mixture that you cannot physically see, but is all around us.
Air.

Describe the particles of a heterogeneous (mechanical) mixture.
Unevenly mixed particles so the different kinds of matter can be seen by the eye

What is a compound? Give an example to support your answer.
A compound is a substance formed when two or more elements are chemically joined (Example: NaCl aka salt)

What is a heterogeneous mixture?
A heterogeneous mixture DOES NOT mix evenly, and you can take it apart.
