EVERYDAY SCIENCE

Detailed explanation-1: -Chemical analysis includes both qualitative and quantitative analysis. 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: -Melting or boiling point is another property that scientists can use to identify a substance. Melting point is the temperature at which a substance changes from solid → liquid. Boiling point is the temperature at which a substance changes from liquid → gas.

Detailed explanation-3: -Hint: In qualitative analysis treatment the properties of unknown substances are determined by reacting it with several reagents. This branch deals with the identification of elements. For a mixture this analysis is carried out to identify the component substances present in it.

Detailed explanation-4: -Gas Chromatography (GC) Gas Chromatography Mass Spectroscopy (GC-MS) Ion Chromatography (IC) High Performance Liquid Chromatography (HPLC) Dispersive Raman Spectroscopy. Fourier Transfer Infrared Spectroscopy (FTIR) More items
