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.
A mixture of pebbles and sand is considered heterogeneous because the individual components (pebbles and sand) are visibly different and do not form a uniform composition throughout the mixture.
A mixture of sand and water would be a heterogeneous mixture because the sand doesn't dissolve within the waterHeterogeneous.See the Related Questions to the left for more information.
sulfur sodium chloride sand is a homogeneous mixture (solution)
Sand is not a homogeneous material.
Homogeneous
This mixture is not homogeneous.
no
Finally divided sand may be homogeneous.
Salt and sand is a mixture.
No, sea water with sand is not a homogeneous mixture. The sand would settle to the bottom, indicating that it is not evenly distributed throughout the solution.

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.
