Sand is a mixture and rarely is only one compound.
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.
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.
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.
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).

Iron is a chemical element; sand may be a compound or a mixture.

Concrete is a heterogeneous mixture composed of cement, sand, gravel, and water. It is not an element or a compound.
Concrete is a mixture containing cement, sand, gravel and water.
someone told me it was a mixture of clay and sand and decaying plants etc.
Sand is a mixture.
sand is a mixture because its all mixeed up with stuff!
Soil is not a compound, mixture, or element—it is a complex combination of minerals, organic matter, water, and air. It is a mixture made up of various components such as sand, silt, clay, organic material, and microorganisms.
its homogeneous...."see-through" examples :coke, kool aid, or redbull...
Sand and pebbles is a heterogeneous mixture. A solution is a homogeneous mixture.
