What are homogeneous and heterogeneous mixtures?
Homogeneous : a mixture where the different parts are evenly distributed throughout, making the individual parts unable to be seen; INvisible parts
Heterogeneous : a mixture where the different parts are not evenly mixed together, meaning you can easily see the separate components; VISIBLE parts
