a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
Yes.
First of all,a solution can also be called a Homogeneous Mixture, and a Homogeneous Misture has an Uniform composition.
''Uni'' means one.
A mixture whose composition is uniform throughout is called homogeneous. Heterogeneous mixtures do not have a uniform composition through out the substance.
A mixture whose composition is uniform throughout is called Homogeneous Mixture.
One that has a uniform composition
such mixture that have the same uniform composition throughout are called homogeneous mixture

it has a definite composition

a pure substance is a substance that entails unchanging/unvarying molecular structure
A pure substance has a fixed and uniform composition.
a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
Table salt is a pure substance. It is combined in such a way that it is uniform and definite in composition.
Table salt is a pure substance. It is combined in such a way that it is uniform and definite in composition.
A substance or object that is not uniform in composition would be a heterogeneous mixture.
A pure substance:cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
Pure iron is a pure substance because it's chemical composition stays uniform regardless of it's sample size. It's matter that appears uniform in appearance and composition, no matter how small the sample size. An example of a pure substance includes pure iron
Pure substance: matter w/properties/composition that don't vary from sample to sample. (salt, water,etc). Homogeneous mixture: composition can vary; an example is a solution (coffee w/sugar) and is uniform throughout.
such mixture that have the same uniform composition throughout are called homogeneous mixture
A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.

No. A pure substances has a definite and constant composition.
