How do properties identify substances?
Properties of substances, such as color, odor, density, melting point, boiling point, and solubility, help to identify them. Analytical techniques like spectroscopy, chromatography, and mass spectrometry are also used to determine the composition and structure of substances. By comparing experimental data with known reference values, scientists can accurately identify substances.
What are the types of electromagnetic radiation commonly used to identify substances?
Common types of electromagnetic radiation used to identify substances include X-rays, gamma rays, ultraviolet-visible (UV-Vis) light, and infrared (IR) radiation. Each type interacts with substances in different ways, providing valuable information about the molecular structure and composition of the material being analyzed.
Why is density characteristic property?
Density is a Characteristic Property because it is A quality of a substance that never changes and can be used to identify the substances.
How can one identify unknown substances?
One can identify unknown substances through various methods such as conducting chemical tests, using spectroscopy techniques, analyzing physical properties, and comparing results with known substances.
How can the boiling and the melting point be used to help identify substances?

Which 4 specific properties cannot be used to identify a substance?
Color, odor, taste, and state of matter are not specific enough to uniquely identify a substance, as multiple substances may share these properties.
What is a logical conclusion the student can draw about pure substances?
A logical conclusion a student can draw about pure substances is that they are made up of only one type of element or compound. This means that pure substances have consistent and predictable properties that can be used to identify and classify them.

What is the role of chemistry in criminal sciences?
Chemistry is used to identify blood, hair, sperm, drugs, gun powder, toxic substances. explosives, etc.
What are the three steps used to identify a material?
The three steps used to identify a material are: observing its physical properties (such as color, shape, and texture), testing its chemical properties (such as reactivity with certain substances), and analyzing its molecular structure using techniques like spectroscopy or microscopy.
