Questions asked by users might not always be phrased in the clearest way.
Sure, here are the key differences between pure and impure substances:
Pure Substances:
* Consist of only one type of atom or molecule.
* Have a definite and constant composition.
* Have uniform properties throughout the sample.
* Examples: distilled water, pure gold, pure oxygen gas.
Impure Substances:
* Consist of two or more different types of atoms or molecules.
* Have a variable composition that can vary from sample to sample.
* Have properties that can vary depending on the composition.
* Examples: seawater, air, granite, alloys.
In summary, pure substances are composed of a single type of particle with a fixed composition and uniform properties, while impure substances are mixtures of different types of particles with variable compositions and properties.
