Basics of Chemistry Question All haircolor products are organic chemicals. Most organic substances do not burn because they do not contain carbon. There are 60 naturally occurring elements, each with its own distinct physical and chemical properties. Sodium chloride is water. The oxidation of haircolor is an example of a physical change. Water and alcohol are examples of miscible liquids. People began making soaps about 4,500 years ago by boiling oil or animal fat with wood ashes. Cold cream is an example of an oil-in-water emulsion of two immiscible liquids. The branch of science that applies to substances that contain carbon is called: All matter has physical and chemical properties and exists in the form of a: a. solid c. gas b. liquid d. All of these answers are correct. The simplest form of chemical matter that cannot be broken down without the loss of identity is a(n): Elements differ from one another because of the difference in the structure of their: Chemically combining two or more atoms produces a: The chemical combination of two or more atoms of different elements produces a(n): Change in the form of a substance that does not cause a chemical reaction is a(n): Chemical reactions that are characterized by or formed by giving off heat are: A chemical combination of matter in definite (fixed) proportions is a: Air contains many substances, including nitrogen, carbon dioxide, and water vapor, and is an example of a: A stable physical mixture of two or more substances is a(n): A substance, usually liquid, that dissolves another substance to form a solution is a(n): Liquids that can be mixed together to form stable solutions are: An unstable physical mixture of two or more immiscible substances is a(n): Substances that allow oil and water to mix, or emulsify, are: Substances used to neutralize acids or raise the pH of many hair products are: An example of an ammonia compound that is used to perform chemical services in a salon is: A sweet, colorless, oily substance that is used as a moisturizer in skin and body creams is: A common volatile organic compound used in hair spray is: An atom or molecule that carries an electrical charge is a(n): Ions with a positive electrical charge are considered to be: A solution with a pH value of 7 indicates a(n): Separation of an atom or molecule into positive and negative ions. Capable of combining with or attracting water (water-loving). Study of substances that do not contain the element carbon, but may contain the element hydrogen. Rapid oxidation of a substance, accompanied by the production of heat and light. Having an affinity or attraction to fat and oils (oil-loving). Chemical reaction in which the oxidizing agent is reduced and the reducing agent is oxidized.
