How do you separate helium and argon to get helium?
To get helium you can use fractional distillation of liquid air.-or-If you just wanted to separate helium from a MIXTURE of helium and argon you could use diffusion. Since helium is lighter than air while argon is heaver than air. You can capture the helium as it "diffuses" away from argon.
What type of mixture could not be separated by filtration?
A homogeneous mixture, such as a solution, typically cannot be separated by filtration because the components are mixed at a molecular level and do not separate based on size like in a heterogeneous mixture. The particles in a homogeneous mixture are too small to be caught by the filter, making filtration ineffective as a separation method.
What is an example of a metal that is in a mixture?
An example of a metal that could be in a mixture is iron (Fe) in a mixture such as iron ore, where it is found along with other elements or compounds. In this case, iron is one component of the mixture that needs to be separated out for further processing or use.
Where is helium useally found?
Helium is usually found in natural gas deposits underground. It is produced as a byproduct of the natural decay of radioactive elements, mainly uranium and thorium, which release helium gas as they break down.
If you have a mixture of gravel and sand and salt and iron fillings what properties of these substances could you use to separate the mixture and how would you use those properties?
You could use a magnet to separate the iron fillings from the mixture, as iron is magnetic while the other substances are not. Next, you could use water to dissolve the salt, allowing you to separate it from the sand and gravel mixture. Finally, you could use a sieve to separate the remaining sand and gravel mixture based on particle size.
