Chapter 12 Basics of Chemistry

Which of these is not composed of organic chemicals:

The ???? is the smallest chemical component of an element:

Liquids that can be mixed together to form stable solutions are:

Solutions that contain undissolved particles that are visible to the naked eye are known as:

Chemically combining two or more atoms produces a:

All matter has a physical and chemical properties and exists in the form of a:

Alph hydroxy acids (AHAs):

This is a substance dissolved into a solution:

The chemical combination of two or more atoms of different elements produces a(n):

Calamine lotion is an example of a(n):

An atom or molecule that carries an electrical charge is a(n):

The chemical reaction that combines a substance with oxygen to produce an oxide is:

Pure substances:

A common volatile organic compound used in hair spray is:

A sweet, colorless, oily substance that is used as a moisturizer in skin and body creams is:

There are 60 naturally occuring elements each has its own distinct physical &chem.l properties.

An example of an ammonia compound that is used to perform chemical services in a salon is:

Rapid oxidation of a substance, accompanied by the production of heat and light.

Cold cream is an example of an oil-in-water emulsion of two immiscible liquids.

Change in the form of a substance that does not cause a chemical reaction is a :

The oxidation of haircolor is an example of a physical change.

A solution with a pH of 7 indicates a(n):

Chemical reaction in which the oxidizing agent is reduced and the reducing agent is oxidized.

Seperation of an atom or molecule into positive and negative ions is:

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:

Capable of combining with or attracting water (water-loving).

An oxidizing agent is a substance that releases:

Sodium chloride is water.

Having an affinity or attraction to fat and oils (oil-loving).

People began making soaps about 4,500yrs ago by boiling oil/animal fat with wood ashes.

A physical combination of matter in any proportions is a:

Volatile organic compounds contain ??? and evaporate very easily:

An unstable physical mixture of two or more immiscible substances is a(n):

Elements differ from one another because of the difference in the structure of their:

A chemical combination of matter in definite (fixed) proportions is a:

The term logarithm means multiples of:

Can be determined w/o a chemical reaction & doesn't involve a chemical change in the substance:

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 are not capable of bing mixed ino stable solutions are considered:

Vapor is a(n) ??? that has evaporated into a gas-like state.

Ions with a positive electrical charge are considered to be:

Any substance that occupies space and has mass is:

The branch of science that applies to substances that contain carbon is called:

This is a substance that acts as a bridge to allow oil and water to mix or emulsify:

Alkanolamines are often  used in place of ammonia because they:

Use of this raises the pH in hair products to allow solutions to penetrate the hair shaft:

Characteristics that can only be determined by a chemical change in the substance are:

All haircolor products are organic chemicals.

Water and alcohol are examples of miscible liquids.

Chemical reactions that are characterized by or formed by giving off heat:

A stable physical mixture of two or more substances is a(n):

The simplest form of chemical matter that cannot be broken down without the loss of identity is

The process thru which oxygen is - or hydrogen is +  to a substance via a chemical reaction is:

Elemental molecules contain two or more ?? of the same element in definite proportions.

Study of substances that don't contain the element carbon but may contain the element hydrogen.

Most organic substances do not burn because they do not contain carbon.

Water-in-emulsions feel ???? than oil-in-water emulsions.
