sand is a mixture because its all mixeed up with stuff!
It is a mixture. In a sand there any many different type of rocks, minerals, dusts and other particles that are not chemically bonded together to be considered a compound.
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; 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.
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
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.
the chemical formula for sand is SiO2, so it is a compound, made from Silicon and Oxygen
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.
