Sand and salt can be considered a heterogeneous mixture when combined because the individual particles of sand and salt remain distinct and can be visually identified. In contrast, if salt is dissolved in water, it creates a homogeneous solution where the salt molecules are evenly distributed and cannot be seen individually. Therefore, the homogeneity or heterogeneity depends on the state of the mixture or solution being considered.
a salt solution is homogenous.
Yes. Salt water is a homogeneous mixture.
homogeneous
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.
If you dissolve the salt and the sand in water the sand will stay beind and the salt would dissappear. But if you want the salt back you can evaporate it off, by boiling the water. (with the dissolved salt in it)
a salt solution is homogenous.
No, sand is heterogeneous.
Sand and salt are heterogeneous because you can clearly see the particles and you can't see through them no matter the density.
A mixture of salt and water, if stirred until the salt is completely dissolved, is a homogenous mixture.
We can found homogenous sands but also heterogenous sands.
No

No,it is a heterogeneos mixture
