What is a pure substance?
A pure substance is not mixed with any other substance or material, and cannot be separated.
100
What is a mixture?
Mixtures are two or more substances that are mixed together but not chemically joined.
100

Give an example of a homogeneous mixture
Peanut butter, ice cream, milk
100
Give 1 example of a heterogeneous mixture.
Trail Mix
200
What are the two main types of pure substances?
Elements and Compounds
200
What are the two main types of mixtures?
Heterogeneous & Homogeneous
200

Type of solution that has exceeded its ability to dissolve solute and has undissolved solute throughout.

Supersaturated

200

Name one method for separating a homogeneous mixture. 

techniques like filtration, distillation, etc.

What is the difference between heterogeneous and homogeneous mixture?

Homogeneous looks the same throughout and are difficult to separate. Heterogeneous can be taken apart and is very easy to tell the parts of the mixture.

300
The periodic table contains what?
Elements
300
What does homogeneous mean?
When a mixture does mix evenly-appears too look the same throughout.
300

What makes water such a good solvent?

Its polarity (pos and neg charges)

300
Give an example of a homogeneous mixture that you cannot physically see, but is all around us.
Air.

What type of heterogeneous mixture contains large particles dispersed? 

Suspension

400
What is a compound? Give an example to support your answer.
A compound is a substance formed when two or more elements are chemically joined (Example: NaCl aka salt)
400
What is a heterogeneous mixture?
A heterogeneous mixture DOES NOT mix evenly, and you can take it apart.
400

Name one factor that affects the rate of dissolving

Solute size

Temperature

Stirring

What two things do you need to create a solution? Be specific.

Solute and Solvent.

400
An solution that has space to dissolve additional solute is considered?

Unsaturated

500
Give three examples of an element.
Iron (Fe), Sodium (Na), Hydrogen (H) etc...

What happens when I combine a solute and a solvent?
You get a solution.
