sand is a mixture because its all mixeed up with stuff!
the chemical formula for sand is SiO2, so it is a compound, made from Silicon and Oxygen
Sand is a mixture; rarely may be an almost pure compound.
Iron is a chemical element; sand may be a compound or a mixture.
Most naturally occurring sand is a mixture, but some especially pure sand is a compound named silicon dioxide. This compound occurs in all other forms of sand.
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.
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.
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 because it is composed of different minerals such as quartz, feldspar, and mica. These minerals are physically combined, not chemically bonded, which means they can be separated through physical means like sifting or filtering.

Sand is a mixture and rarely is only one compound.
