answer:</h2>
a heterogeneous mixture
<h2>
explanation:</h2>
A heterogeneous mixture is commonly any mixture that is not uniform in combination - it's a non-uniform mixture of smaller fundamental particles. Using different means, the particles in the mixture can be separated from one another. In a heterogeneous mixture, the elements do not mix completely, and the individual items that form the mixture can be identified. Heterogeneous mixtures can typically be separated back into their original components by chemical or physical means.
