Sand is a mixture (but it is important to mention that some times sands formed from silicon dioxide, calcium carbonate, lava, shells may be not considered as mixtures); sands may be homogeneous but also heterogeneous.
Wet sand is considered heterogeneous because it contains a mixture of different-sized particles that are not uniformly distributed.
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.
We can found homogenous sands but also heterogenous sands.
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.
No because the pieces of sand were the same so that would be a homogenous mixture. Heterogenous mixtures are noticeabley different from one another. Thank you very much :)
Sand and pebbles
depends if its homogenous or not
No
depends if its homogenous or not
no, heterogeneous
no, heterogeneous
A homogenous mixture is one containing a number of particles of the same substance, while a heterogenous mixture contains particles of different substances. For example, a handful of sand would probably be considered a homogenous mixture because it only contains sand particles, while a handful of mud would be a heterogenous mixture because it contains particles of dirt, water, sand, rocks, etc.
