Sand and salt are heterogeneous because you can clearly see the particles and you can't see through them no matter the density.
Sand+salt: a heterogeneous mixture.
This mixture is not homogeneous.

Sand and salt are heterogeneous because you can clearly see the particles and you can't see through them no matter the density.
Heterogeneous if there is salt on the outside, homogeneous if they are just plain.
Yes, salt is homogeneous.
Sand with shells is a heterogeneous mixture because it contains different components (sand and shells) that are visibly different and can be separated easily. In a homogeneous mixture, the components are evenly distributed and not easily distinguishable.
Yes. A heterogeneous mixture is one that lacks uniformity. When salt water (a homogeneous mixture) and sand are placed in the same container, the sand sinks to the bottom and the salt solution remains, largely, above the sand, demonstrating the characteristic lack of uniformity. See related link, below.
homogeneous
Salt water. Homogeneous means that you can't see the particles
