* Homogeneous mixtures have a uniform composition throughout. This means the components are evenly distributed and indistinguishable from one another. Think of sugar dissolved in water – you can't see the individual sugar molecules.
* Heterogeneous mixtures have visible, distinct components. The components are not evenly distributed and can be easily separated.
Salt water and oil:
* Salt (NaCl) dissolves in water, creating a homogeneous solution (saltwater).
* Oil is nonpolar, while water is polar. These differences in polarity make them immiscible, meaning they don't mix. Oil will float on top of the water, forming two distinct layers.
Therefore, salt water and oil are a heterogeneous mixture, not a homogeneous one.
