The mixture you separated was mixture oof iron filings, sand, and salt. based on your understanding of matter, is this mixture a homogeneous mixture or heterogeneous mixture? how do you know? a. heterogeneous mixture-the parts are not uniformly mixed. b. homogeneous mixture-the parts are uniform mixed c. heterogenous mixture-the parts are uniformly mixed d. homogenous mixture-the parts are not uniformly mixed

Heterogeneous mixture

A mixture forms when different elements are put together and yet they are distinct. it means there is no change in the properties of individual components of a mixture. A mixture can be of two kinds: Homogeneous and Heterogeneous mixture. A homogeneous mixture is the one which has uniformity in its every part. For example: salt mixed in water is a homogeneous mixture. A heterogeneous mixture has visibly distinct components. The mixture was of iron fillings, sand and salt is a homogeneous mixture as the component parts are not uniformly mixed.
