Mixtures
Solution>Saturated Solution / Suspension>Emulsion / Coloid Definition: A material formed by physical combining of two or more materials. Substances keep their own properties.
Solutions
A mixture of one substance, dissolved throught another. All parts of the solution have the same properties such as color, odor and taste
Solutions-Examples
Borax solution, sugar water, instant tea
Saturated Solutions
A solution that is full of the dissolved substance.
Saturated Solutions-Examples
Sugar water, chicken broth, soda/pop
Solute
A substance that becomes dissolved.
Solute-Examples
Sugar, sugars in pop
Solvent
The part of the solution that dissolves the substance.
Solvent-Examples
Water (H2O)
Alloys
Solutions of two or more metals and other solids.
Chemical
Any substance used in or obtained by a chemical process
Elements, Ancient Times
When people first discovered fire, the carbon from burned wood was left in the forrest. Carbon is an element. An element is a substance entirely of atoms of a single kind.
Periodic Table of Elements
Their identified by symbols, such as H for Hydrogen and O for Oxygen. These symbols are used when writing chemical formulas and chemical reactions
Compound
A combination of two or more elements
Physical Properties
Includes whether it is solid, liquid, gas. Its color and odor and its freezing and boiling points.
Chemical Properties
related to its reaction with other substances
Chemical Interactions
The formation of one or more new substances.
States of Matter
Form in which a substance comes in solids, liquids of gases.
Transparent
Light can travel through clearly
Translucent
light can go through but not clearly
Opaque
Light will not travel through material
Dissolving
To mix completely with a liquid
Reaction
two or more substances undergoing a chemical change
Evaporation
a change from a liquid/solid to a vapor
Saturation Point
the point at which the solution holds as much as it can.
Super Saturation
A solution holds more of a substance when heated than when normally disolved at cooler temperatures
Suspension
A mixuture made of different parts that will separate with time.
Polymers
Molecules with long chains of separating units.
Magnesium Ribbon
Chemical-Gas color smelled / Physical-Fizzy and balloon blew up, balloon popped
State

Melting Point
The temperature at which a substances changes from a solid to a liquid is called its _____
Boiling Point
The temperature at which a substances changes form a liquid to a gas is called its _____
Heat
The particles of a substance will move faster if _____ is added to it.
Physical Change
Any change that does not produce new substances is a _____
Solid
Something that has a definite shape and volume is called a _____
Liquid
Something that has a definite volume and takes up the shape of its container is called a _____
Solvent
The part of a solution that dissolves a substance is called _____
Chemical Change
New substances are produced with physical properties different from the starting substance is a _____
Equals
The total mass of all starting substances _____ the total mass of all new substances in a chemical change.
