How to prove that there are brass in sand?
To prove that there are brass particles in sand, you can perform a simple experiment by using a magnet. Brass is not magnetic, so if you pass a magnet over the sand and some particles are attracted to the magnet, it indicates the presence of a metal like brass in the sand. You can then separate the brass particles from the sand using the magnet as proof.
Why is coarse sand and salt not a homogeneous mixture?
Coarse sand and salt are not a homogeneous mixture because they do not have a uniform composition throughout. While the two components may be mixed together, they do not blend seamlessly at a molecular level, resulting in visible separation of the sand and salt particles.
Can you separate the two substances salt and sand?
You can't use the same mixture because,a mixture of sand and water is a heterogeneous mixture.In this mixture the particles are not uniform which means they can't desolve into one an other,but the mixture of salt and water is a homogeneous solution because the particles can be desolve into one another to form a solution.
How do you separate sand salt and sawdust into pure states?
If all three are mixed together you can separate the sawdust from the group with a Sieve filter with holes smaller than the sawdust, but larger than the sand/salt particles. You could then use another sieve, if the sand and salt particles are significantly different in size,...OR add water to the mix....the salt will dissolve into solution leaving the sand behind. Pour off the water and let it evaporate, leaving the salt behind. Put the mixture of sand, salt and sawdust into a quantity of water: the sand will sink to the bottom, sawdust will float and salt will dissolve. Skim off (and dry) the floating sawdust. Pour off the water containing the dissolved salt. This is then heated to cause all the water to evaporate (leaving behind the salt). The remaining residue in the original container (wet sand) can now be dried off with heat.
What is a mixture where the particles can be easily seen and separated?
A heterogeneous mixture is one where the components are visibly different and can be easily separated using physical methods like filtration or sorting. Examples include a mixture of sand and salt, where the sand particles can be seen and separated from the smaller salt particles.
Is salt and sand a liquid?
Because it is made up of small, solid particles.
How to prove that there are brass in sand?

You can then separate the brass particles from the sand using the magnet as proof.
What methods do you think you will use to separate sand from salt?
One method to separate sand from salt is by dissolving the mixture in water to dissolve the salt, then filtering the solution to separate the sand from the saltwater. Another way is to use a sieve to physically separate the larger particles of sand from the smaller particles of salt.
Is salt and sand a heterogeneous or a homogeneous?
Sand and salt are heterogeneous because you can clearly see the particles and you can't see through them no matter the density.
Why do sand take longer to melt ice then salt?
The reason why it takes sand to melt ice longer than salt does, is because salt draws or absorbs the moisture in the ice faster than sand that just has a rough texture. Yes, there is salt particles in sand but not as much as normal salt by itself.
How can you separate salt and sand?
You can dissolve the sand and salt into the water. when this happens the salt will be dissolved and the sand will stay at the bottom. then get some filter paper and pour the mixture through it. the dissolved salt and water will go through leaving the sand. there you have the sand aside. to get the salt aside just boil the water until it evaporates completely and you will be left will your salt. then you have your sand and salt separated. by sifting it
Why is coarse sand and salt not a homogeneous mixture?
Coarse sand and salt are not a homogeneous mixture because they do not have a uniform composition throughout. While the two components may be mixed together, they do not blend seamlessly at a molecular level, resulting in visible separation of the sand and salt particles.
Where does the salt come from in the Atlantic Ocean?
Salt comes from rocks. When water wears down rocks at the beach particles of sand are washed into the ocean.

Is salt and sand homogenous or heterogenous?
Sand and salt are heterogeneous because you can clearly see the particles and you can't see through them no matter the density.
How do you separate salt and sand from water?
You can separate salt and sand from water by performing a simple filtration. First, pour the salt and sand mixture through a filter paper to trap the solid particles. Then, evaporate the water from the filtrate to recover the dissolved salt, leaving the sand behind.
