the science that deals with the composition, structures & properties of matter
What is Chemistry
100
All matter exist in one of three physical forms
What is 1. Solid 2. Liquid 3. Gas
100
Matter can be change in two different ways
What is Physical change & Chemical Change
100
This measures the acidity & alkalinity of a substance
What is pH scale
100
Liquids that can be mixed into a stable solution
What is Miscible
ex= Water & Alcohol
200
the study of substances that contain carbon
What is Organic Chemistry
200
the simplest form of matter & cannot be broken down into a simpler form without a loss of identity
What is Element
200
A chemical combination of matter, in definite, exact proportions
What is Pure Substance.
ex. Water = 2 atoms of hydrogen
1 atom of oxygen
= H2O
200
an atom or molecule that carries an electrical charge
What is an Ion
200
Liquids that are NOT able to be mixed into a stable solution
What is Immiscible
ex.= Water & Oil
300
the study of substances that do not contain carbon
What is inorganic chemistry
300
all matter in the universe is made up of what
What is 90 different elements
300
a combination of matter in any proportion
What is Physical mixture
ex. Saltwater=
a mixture of salt & water in any proportions is still saltwater
300
only products that contain this can have a pH
What is Water
products with NO water in it will not have a pH
300
A surfactant has two distinct parts that act as a bridge to allow oil & water to mix. What are they
What is 1. Hydrophilic - water loving head
2. Lipophilic- oil loving tail
400
any substance that occupies space & has mass (weight)
What is Matter
400
particles from which all matter is composed, the smallest particle of an element that retains the properties of that element
What is an Atom
400
An unstable mixture of undissolved particles in a liquid, they separate over time
What is Suspensions
ex. oil & vinegar salad dressing, some lotions,nail polish & Calamine lotion
They need to be shaken well before using
400
Hair & Skin have a pH of what
What is pH of 5
400
This is a substance used to neutralize acids or raise pH of many hair products
What is Alkanolamines
500
Gasoline, motor oil, pesticides, haircoloring products, relaxers, shampoos & conditioners are all concidered what
What is Organic
500
a chemical combination of two or more atoms
What is a molecule
500
A unstable mixture of two or more immiscible substances united with the aid of an emulsifier
What is Emulsions
the difference between Suspension & Emulsions is that Emulsions separate SLOWLY over time
ex. Shampoos & Conditioners
500
The pH scale measures the acidity & alkalinity of a substance, the pH scale has a range of
What is 0-14
500
When oxygen is added to a substance, the substance is OXIDIZED, When oxgen is subtracted from a substance the substance is REDUCED. This chemical action is called
