Homogenouse
no
Something of a similar nature in short.
No, water is a pure substance. It is a compound.
Finally divided sand may be homogeneous.
For example filtration, manual collection.
yes, salt water is a homogenuous mixture.
Summer sausage is a mixture of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures of mixtures, etc. wrapped in a mixture.
hello
Mixtures can be separated by evaporation, distillation, filtration, chromotography, and lastly precipitation (which involves additional steps). Solid mixtures can be separated through vibration (as in a bin where heavier objects rises to the top and smaller objects sink to the bottom). With magnetism in certain metallic objects, with the use of sieves, wind blows lighter objects (heavier objects are retained). You can dissociate salts in liquids and rinse them away. You can separate different grains with your fingers or with the help of tweezers or something else. You could also use the help of bacteria, or maggots or similar insects to eat away organic material etc. etc
to be able to test certain liquids and such needed to study something, chemistry comes in with mixtures of different objects
True, by the years scientists have tryed to "invent" many objects for some kind of use however trying to "invent" can turn out as a victory scientists can come up with many objects.
