EVERYDAY SCIENCE

Detailed explanation-1: -So the answer to the question “Which of the following terms best describes the identification of an unknown substance and the determination of its chemical composition?” is (A) chemical analysis.

Detailed explanation-2: -Analytical Chemistry An analytical chemist may use complex instruments to analyze an unknown material, in order to determine its various components.

Detailed explanation-3: -Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount.

Detailed explanation-4: -Qualitative analysis → The process of identifying what types are present in the sample. Quantitative analysis → The process that serves to establish in numerical terms the quantity of one or more of the components in a sample.

Detailed explanation-5: -Analytical Chemistry is the study of chemical characterization of matter. It provides the methods and tools to deduce the qualitative, spatial, quantitative, and speciation aspects of analytical science. An analytical chemist is a scientist who studies the composition and structure of matter.
