Final Study Guide

You can find the study guide HERE.
Or you can just view it below. I will have practice problems for you to try in class on Friday, but you can start reviewing now.

Spring 2012 Final Study Guide

For this final you will be allowed to have one 3x5 notecard or a 3x5 piece of paper along with your periodic table. I recommend reviewing past tests, your notes and the class notes which are available HERE. You can access the website by doing a google search for “Mattys Physical Science.” The notes are available as a google doc or a PDF. Here is what will be on the final. (I hope you learned a lot this semester!)
Mass vs Weight- be able to explain the difference
Classifying Matter- Matter, Pure Substance, Mixture, Element, Compound,

Homogeneous Mixture, Heterogeneous Mixture. (See the notes slide 40)

Temperature- Be able to convert from Celsius to Fahrenheit and Fahrenheit to Celsius
What happens to molecular motion as temperature increases?
Absolute zero, solid, liquid, gas, plasma

Phase Change- What does the graph look like during melting and boiling

 What does it mean when the temperature stays the same during

melting and boiling even though you continue to heat the substance?

What happens to intermolecular forces as temperature increases and phas change occurs?

Which substances have greater intermolecular forces?

What is the difference between boiling and evaporation?

Atomic Structure-

Electric Charge-is a property of all matter. Opposites attract. Same charges repel

Electrons, Protons, Neutrons (Which is bigger?)

Nucleus, Energy Levels

What holds the atom together

How are atoms of each element different

What makes an atom complete

What are ions

What is an isotope

Be able to draw any of the first 20 atoms and the number of electrons they have

How do we know energy levels exist?

Understand relationship between energy levels and color

What’s the difference between a mass number and atomic mass?

Periodic Table

Groups, Periods, Metals, Non-Metals, Metalloids, Alkali metals, Group 2 Metals, Halogens, Noble Gases, Transition Metals, Valence Electrons

Physical vs Chemical Change and examples of each

Explain how and why bonds form

Ions and their charge (How do you find the charge of an ion?)

Ionic vs Covalent Bonds (How are they different?)

Be able to draw Lewis Dot Structures for elements. Know the Octet Rule.

Oxidation Numbers, Criss-Cross Method

Polyatomic Ions   

Chemical Reactions- Reactants, Products, Yield
Conservation of Mass Be able to balance chemical equations
Types of Chemical Reactions: Composition, Decomposition, Single Displacement,

Double Displacement, Combustion

Exothermic vs Endothermic (How are they different)

Formula Mass vs Molar Mass (Be able to find the Molar Mass of a compound)

Acid vs Bases (How do they relate to the pH Scale)
