Question

The mixture you separated was a mixture of iron filings, sand, and salt. Based on your understanding of matter, is this mixture a homogenous mixture or heterogenous mixture? How do you know? Question 1 options: homogenous mixture-the parts are uniformly mixed homogenous mixture-the parts are not uniformly mixed heterogenous mixture-the parts are not uniformly mixed heterogenous mixture-the parts are uniformly mixed

Answer 1

Answer: Heterogeneous mixture - the parts are not uniformly mixed.

A mixture contains components having distinct chemical properties. There are two types of mixtures: homogeneous and heterogeneous. In a homogeneous mixture there is uniform distribution of components. we cannot distinguish one portion of the mixture from another. for example salt mixed in water. In heterogeneous mixture, the components are not uniformly mixed. hence, we are able to distinguish different parts of a mixture, like the mixture of iron, sand and salt given in this question.

Answer 2

This would be a heterogenous mixture. Nothing was dissolved in anything else. The things could not have been mixed completely evenly because of their different weights and densities. Homogenous mixtures are usually solutions where one thing is dissolved in another and can't be easily separated out by hand.
