What is homogenous and heterogeneous ?
A heterogeneous mixture is simply anymixture that is not uniform in composition – it's a non-uniformmixture of smaller constituent parts. Using various means, the parts in themixture can be separated from one another.
A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixturehas components whose proportions vary throughout the sample.
