Any substance that occupies space and has mass (weight)

What is Matter?

100

A type of change in the form or physical properties of a substance 

What is physical change?

100

A stable, uniform mixture of two or more substances 

What is a Solution?

100

Substances that allow oil and water to mix or emulsify

What are Surfactants? 

100

An atom or molecule that carries an electrical charge

What is an Ion?

200

The simplest form of chemical matter and contains only one type of atom.

What is an Element? 

200

A chemical combination of matter in definite (mixed) proportions

What is a pure substance?

200

The substance that dissolves the solute and makes the solution

What is a Solvent?

200

The head of the surfactant molecule capable of combining with or attracting water

What is Hydrophilic?

200

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

What is Ionization? 

300

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

What is Chemistry?

300

A type of change in the chemical composition of makeup of a substance 

What is Chemical change?

300

Unstable physical  mixtures of undissolved particles in a liquid

What are Suspensions?

300
Oil droplets are emulsified in water 

What is an oil-in-water emulsion

300

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

What is Oxidation-reduction?

400

Basic unit of matter, with a nucleus at the center surrounded by negatively charged electrons that move around the nucleus in orbits

What are Atoms?

400

a physical combination of matter in any proportion (combined properties in a mixture)

What is physical mixture?

400

Mutually soluble, meaning that they can be mixed together to form solutions

What are Miscible (liguids)?

400

aka the tail; having an affinity for or an attraction to fat and oils

What is Lipophilic?

400

When certain chemical reactions release energy in the form of heat

What is Exothermic Reaction?

500

A c chemical combination of two or more atoms in definite (mixed) proportions

What are molecules?

500

Characteristics that can be determined without a chemical reaction and involve chemical change in a substance 

What are physical properties?

500

Should be used within one year of purchase but can be stable up to 3 years under ideal conditions

What are cosmetic emulsions?

500

The first surfactants; people started making this about 4500 years ago by boiling oil or animal fat with wood ashed

What is soap?
500

used to measure the acidity and alkalinity of substances
