No. A pure substances has a definite and constant composition.
pure substance
homogeneous mixture
I am not 100% sure, but i believe variable composition is when the composition of a mixture can vary, or contain different properties, elements/compounds... etc. An example of variable composition would be a heterogeneous mixture, which has no uniform way of being composed. Where as its opposite, a homogeneous mixture, has a set composition of the same properties, elements/compounds... etc. and can be recreated.
The percentage composition of a mixture has nothing to do with its homogeneity or otherwise. A mixture is homogeneous if its percentage composition - whatever that is - is the same throughout the mixture.
homogeneous because it the same composition
No. The composition of a homogeneous mixture, called a solution, can vary.

A compound has a fixed composition and is always a homogeneous pure substance.
The coins are of homogeneous composition.
The answer is a Homogeneous mixture
The percentage composition of a mixture has nothing to do with its homogeneity or otherwise. A mixture is homogeneous if its percentage composition - whatever that is - is the same throughout the mixture.
homogeneous because it the same composition
Homogeneity and heterogeneity are concepts relating to the uniformity in a substance. A material that is homogeneous is uniform in composition or character; one that is heterogeneous is distinctly nonuniform in one of these qualities
Nonstoichiometric compounds have a variable composition.
No. The composition of a homogeneous mixture, called a solution, can vary.
a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
Sand is not a homogeneous material.
