Question
Chapter 1, Problem 10E
Interpretation Introduction
Interpretation:
The given molecular diagrams of substances are to be classified as pure substances or mixtures and are to be further classified as compounds or elements in case of pure substances and as heterogonous or homogenous in case of mixtures.
Concept introduction: A compound is a substance in which two or more different elements combine together by a chemical compound
A substance consisting of only one species (elements or compound) is called pure element.
A mixture in which composition of its constituent is uniform throughout the solution is called homogenous mixture and their constituents are indistinguishable.
A mixture in which composition of its constituent is not uniform throughout the solution is called heterogeneous mixture.
To determine: The categorization of the given substances as pure substances or mixtures.
