Sand is not a homogeneous material.
No, if sand is included its heterogeneous.
Beach sand is a heterogeneous mixture
Sand and chalk are not a homogeneous mixture because they do not have a uniform composition, meaning their components are visibly distinguishable from each other. Sand consists of larger particles like silica, while chalk is composed of calcium carbonate.
Sand, for the most part, is homogeneous. If you go to the beech, the particles of sand are of uniform size and chemical composition. Although you might find a foreign object, such as a coin, an article of jewelry, a cigarette butt, or a piece of shell, sand is very consistent and uniform; therefore, it is homogeneous.
Coarse sand and salt are not a homogeneous mixture because they do not have a uniform composition throughout. While the two components may be mixed together, they do not blend seamlessly at a molecular level, resulting in visible separation of the sand and salt particles.
Homogeneous
This mixture is not homogeneous.
no
Salt and sand is a mixture.
Finally divided sand may be homogeneous.
No, if sand is included its heterogeneous.
I don't know
Beach sand is a heterogeneous mixture
No, carbon mixed with sand is not a homogeneous mixture. It would be considered a heterogeneous mixture because the carbon and sand do not completely mix at a molecular level and can be visibly distinguished from each other.
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.
Sand itself is homogeneous (each grain is homogeneous), however sand in general (lots of grains of sand, as in a handful of sand) is heterogeneous because it both has other things than sand mixed in and also it is not a pure solid (it is not a large rock of sand).See the Related Questions to the left for more information about heterogeneous and homogeneous mixtures.Sand itself is a homogeneous but it's not a mixture. It's a compound. If your talking about a bucket of sand it isn't uniformed throughout it would be a heterogeneous mixture because it's uniform of each piece of "sand" varies. It would be a homogeneous mixture if all the sand in the bucket where the uniformed throughout. For example if all the specs of sand in the bucket are SIO2 silicon dioxide it is a homogeneous mixture.Chemistry the central science 11 editions and their book still confuses people. You think they could explain what they are talking about a little bit better. It's only a 400 dollar book.
Sand and pebbles is a heterogeneous mixture. A solution is a homogeneous mixture.
