Sand is a mixture and rarely is only one compound.
Sand is made form a mixture of mineral grains (mainly quartz or calcite) which are themselves compounds. If there is water or air flowing though the sand at a fast rate, then it can also be a suspension.
The purest sand is a compound, silicon dioxide. Most ordinary sand, however would contain some other materials and could be either a homogeneous or a heterogeneous mixture.
It's a compound. H2O - Two hydrogen atoms, one oxygen atom Water is a compound as it can be reduced to simpler elements (Oxygen and water).It is a homogenous mixture("the same") as it is uniform throughout. E.g: Salt and sand mixed together would be a heterogenous mixture("different") as you can distinguish between sand and salt. A pure 'mixture' is usually homogenous, especially liquids.
It is heterogeneous because the sand is not dissolved in the water. Apparently, the sand is still visible from the outside, unlike perhaps salt water in which the salt can no longer be seen.

Iron is a chemical element; sand may be a compound or a mixture.
Which one is mixture carbon dioxide = compound silicon = element silicon dioxide = compound or sand = mixture so sand is the answer.
heterogeneous- it can be undone

Concrete is a mixture containing cement, sand, gravel and water.
Glass is not an element nor a compound , but a mixture of silicon dioxide (sand) , sodium carbonate.
someone told me it was a mixture of clay and sand and decaying plants etc.
Sand on the beach is a mixture of compounds. Pure sand is white and its chemical name is Silicon Dioxide (SiO2)' a compound. The red brown colour comes from iron(III) salts mixed in ther sand. The Iron(III) saltsd will also be a mixture of compounds.
Sand is a mixture.
its homogeneous...."see-through" examples :coke, kool aid, or redbull...
