heterogenous mixture deifnition
mixture where you can see the separate components of the mixture
homogenous mixture
mixture where you can’t see the separate components of the mixture, but aren’t chemically combined
solution definition
another way of saying homogenous mixutre
suspension definition
another way of saying heterogenous mixture
colloid definition
the inbetween a homogenous and heterogenous mixture where you can tell that there are two components, but they can’t be separated
