Explanation:
Mixtures can be:
1- homogeneous mixtures or solutions: they are uniform everywhere in the mixture, their particles are so small that they mix evenly. Light passes through them without scattering and they don’t settle down. They can’t be filtered too. Under the microscope they look uniform, you can’t distinguish any component. Example: salt and water
2- heterogeneous or mechanical mixtures: they are non uniform, which means that components are not mixed evenly. Particles are intermediate to large in size. You can distinguish different parts either with the naked eye (ex salad) or under a microscope (ex blood). They scatter light and if it’s in a liquid medium it can be filtered.
all mixtures can be separate by some physical means.
