homogeneous mixture
C.
heterogeneous mixture
D.

E.
compound

Answer 1

Heterogeneous mixtures are not uniform. you can always sort two substances from each other.

Answer 2

Answer: C.  heterogeneous mixture

Explanation:

Homogeneous mixtures  : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different. There is no physical boundary between the dispersed phase and dispersion medium. Example: sand in water

Heterogeneous mixtures  : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different. There is a physical boundary between the dispersed phase and dispersion medium. Example: sugar in water

Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper $Cu$

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water $H_2O$
