mixture in what state u want to know?? gaseuos, liquid or solid?? if gaseous, commonly we use burning, or absorption method. if liquid, non metal with non metal, or non metal with metal by using electrolysis to separate. if in solid metal with non metal, use magnet. as such, salt water, boiling, filtration is involved.
To obtain pure components, to remove undesired components
Because we need frequently pure components.
we separate different components to get rid of harmful components
we need to separate to remove undesirable components. To remone undesirable components.
to obtain pure components and to remove undigested components
The centrifuge separates the plasma from the platelets.
In Gas Chromatography, before you can correctly separate and identify the components, you need to vapourise the mixture first. How fast a substance vaporises is dependent on their vapour pressure. In Liquid Chromatography, there is no need to vapourise the mixture and hence vapour pressure is not important here.
Blood donations are separated because the various components of blood can be donated to different people as they may need only one of them (e.g. platelets).
One common reason why you need to do this is to add vectors. If you have two different vectors, and want to add them - algebraically, of course - then you first need to separate them into components. After you do that, you can easily add the components together.
We separate mixtures for many things. It can be used for cleaning (filtering) our water. This is done by FILTRATION;when the substances in a mixture have different particle sizes, they are separated by filtration. The more different the properties are, the easier it is to separate the substances.Read more: SEPARATING MIXTURES http://www.infoplease.com/dk/science/encyclopedia/separating-mixtures.html#ixzz3OjF9dZjT
You need a magnet to separate iron from a mixture (not from a compound).
Yes- a heterogeneous mixture to be more accurate.
If you need to make an intoxicating drink you can distill a mixture of alcohol and water to make spirits.
in order to separate soil from a soil water mixture, we need to boil it, so it will separate both the soil and water will evaporate.
