Why mixture are heterogeneous?

The definition of a heterogeneous mixture is one which does not have a uniform composition and has visible sharp boundaries. Heterogeneous mixture are those in which the substances are not distributed evenly. They usually involve a mixture of a solid in a solid.

The main difference between solutions and mixture is that a solution can only be separated into its original components by chemical means whereas a mixture can be separated by mechanical means. For example, if you mix sugar granules in a glass of water, the sugar granules completely dissolves in the water. This sugar solution is an example of homogeneous mixture.

Now if you want to separate the sugar crystals from the sugar solution it is not possible to do so by mechanical means. For this you have to first boil the sugar solution so that all the water evaporates into the air and the sugar crystals will be left behind I got my answer on this site: buzzle.com/articles/heterogeneous-mixtur....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
