Interpretation: The role of
Concept Introduction : Chemistry is the branch of science that examines the characteristics, make-up, and structure of substances, as well as the changes they go through, and the energy released or absorbed.

Answer to Problem 5LC
Applied chemistry is related to the application part of chemistry and used in identification of various rocks and minerals.
Explanation of Solution
Analytical chemistry is the field of study that gathers, examines, and propagates information regarding the composition and structure of matter.
The composition of matter is a subject of analytical chemistry. To determine the make-up of the rock, a geologist would consult an analytical chemist.
