chemical compounds can be separated into their component elements by physical means like sifting or filtering
Materials in a mixture can be separated by using physical methods.
No, it is not true.
Heterogeneous mixtures are mixtures that can easily be separated. For instance, sand mixed with water is a heterogeneous mixture that can be separated by filtration. Another example of a heterogeneous mixture is salt mixed with pebbles, which can be separated by adding water to the mixture.
Two kinds of heterogeneous mixtures are soil and sand. Sand can have rocks, shells and other elements. Any of these elements like rock can be separated via sifting.
Using adequate procedures of separation it is possible.
Trail-mix is a heterogeneous mixture: It contains visually different solid materials.
Filtering :)

yes
homogeneous and heterogeneous mixtures are separated by evaporation
Yes. Try using a separation flask.

Schools often want to have heterogeneous groups of students.

Mixtures can be homogeneous but also heterogeneous.
