The difference between Compounds

and Mixtures Cartoon

•Heterogeneous mixture - is NOT uniform throughout– each substance can be

visibly distinguished (ex: salad)

•Homogeneous mixture – IS uniform throughout –the substances are evenly

mixed and cannot be visibly distinguished (ex: kool aid)

–Also called a solution
