Answer:

Chemical W is a pure substance

Explanation:

We can conclude that the substance W is a pure substance. Matter on a broad basis can be classified as either pure or distinct substance and impure substances (mixtures).

  • Pure substances are elements and compounds.
  • All the parts are homogenous.
  • They have a definite composition.
  • They cannot be split by physical means.

So, since we can only split the substance into elements X, Y and Z with no simpler units, W is a compound and a pure substance.
