Answers
Solution:
Homogeneous Mixtures Heterogeneous mixtures
The elements and compounds are uniformly mixed. The elements and compounds are not uniformly mixed.
The properties of the mixture are the same in all compositions. The properties differ at different compositions.
Copper and Zinc are two solids which make brass, which is solid. The elements cannot be distinguished. In the mixture of Iron and Sulphur, iron can be easily separated using a magnet, the composition is not uniform.

Answer:
In Homogenous mixtures, the whole mixture is in the same phase whereas in Heterogeneous mixture, substances can be of two phases and layers may separate. Homogeneous mixture could be exemplified as a sugar solution or salt solution whereas Mixture of salt and sand could be used as an example of Heterogeneous mixture.
