look up a picture of granite. Is it one similar looking blob, or can you see more than one color or texture in it? if you can see different colors or textures, it's not homogeneous.
Granite is a heterogenoues mixture. Brass is homogeneous.
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.

TNT (trinitrotoluene) is a homogeneous substance. It is a yellow crystalline powder with uniform composition throughout.

Homogeneous substance
Granite is a heterogenoues mixture. Brass is homogeneous.
Sugar is a compound, which is a homogeneous substance, but not a mixture.
It's obvious from a cursory visual inspection that it's hetereogeneous. Anything with swirls, or specks, or any pattern other than a solid color is hetereogeneous (the reverse is not necessarily true; being a solid color does not always mean that it's homogeneous).
homogeneous have same substance in mixture.heterogeneous have two different substance.
