Not always. There are 3 types of mixtures: heterogeneous, homogeneous, colloid, and alloys. These are the properties of these 3 mixtures: Heterogeneous: mixtures that can be easily separated Exp.: trail mix Homogeneous: mixtures that looks the same throughout and can be evenly mixed Exp.: salt water Colloid: a mechanical mixture where one substance is dispersed evenly throughout another. So here are the properties of these mixtures. Now you know that not all mixtures are homogeneous.
Imagine you are an industrial chemist.part of your job is to think of new and interesting mixtures that your company can make.Using the following list of substances and their properties,name 3 mixtures that you could make,inventing a name and use for each one.Also decide whether it will be a heterogeneous mixtures or a solution.
