A substance that releases oxygen

Characteristics that can only be determined by a chemical reaction and a chemical change

The tail end of a surfactant molecule is lipophilic which means it is

The substance that dissolves the solute and makes the solution

The head of the surfactant molecule that is water loving

Examples of compound molecules

The three states of matter

This has definite volume but takes the shape of its container

A chemical combination of two or more atoms of different elements in definite proportions

Examples of chemical properties include

A physical combination of matter in any proportion

An unstable physical mixture of two or more immiscible substances, plus a special ingredient called an emulsifier

A 7 on the pH scale is

Alkaline substances used to neutralize acids,raise the pH of many hair products, they are often used in place of ammonia

Cold creams, styling creams and lip balms are examples of

A pH scale measures the acidity and _________of a substance

A change in the chemical compositions or make up of a substance

Also known as redox, is a chemical reaction in which oxidation and reduction take place at the same time

The study of substances that does not contain the element carbon

Water and alcohol are examples of

What are ammonium hydroxide and ammonium thioglycolate

There are ________known elements today

An example of a chemical change is

An ion with a negative electrical charge

The simplest form of chemical matter

This is an atom or molecule that carries an electrical charge

Salt water is an example of a

Types of chemical reactions that gives off heat, usually the client cannot feel the heat being released

An ion with a positive electrical charge is a

I am going to study really hard so that I can pass Chapter 12 test

Pure water has a pH of

Alkalis are known as

This is a stable physical mixture of two or more substances in a solvent

Liquids that are mutually soluble , meaning that they can be mixed together to form clear solution

All hair color products , texturizers, shampoos are

Substances that allow oil and water to mix, or emulsify, it is a contraction for surface acting agent

A combination of matter in definite fixed proportions, aluminum foil is an example

The separation of an atom or molecule into positive and negative ions

The basic unit of matter with a nucleus at the center surrounded by negatively charged electrons

The rapid oxidation of a substance accompanied by the production of heat and light

The study of substances that contain the element carbon

Air is a physical mixture and contains many substances including

There are _____ naturally occurring elements each with it's own distinct physical and chemical properties

A common VOC used in hairsprays is

The science that deals with the composition , structures and properties of matter changes under different conditions

This is a sweet colorless oily substance used as a solvent

VOC's are compounds that contain _________and evaporate very easily
