Midterm Study Guide 2015
The midterm will cover the material in the textbook from chapter 1 to chapter 5 and some
parts of the technology section at the end of the book, but only the sections with the
designation ‘ST’. The information I am providing you with is to help you study, it does
not encompass EVERYTHING that will be on the exam (you need to know your notes
pretty well). Try re-writing your notes into your own words, as this will make them easier
to remember. Make sure you know these concepts well, and get lots of practice doing
calculations! Facilelearning.com is also a great resource. Here are some textbook
pages/questions that will help prepare you for the exam.
Pg. 32-34 #13-18, 29-31
Pg. 62 #1-6,20, 21,23, 27, 31,33
Pg. 99 #3,5
Pg. 132 #3, 6, 18, 22
Pg 173 #10-18
Chapter 1:
 The periodic table- what are periods? What are groups? How do you determine
how many electrons are in an element? How about how many electrons are in its
valence shell?
 How to represent an atom- know how to make a Rutherford-Bohr diagram and
Lewis structures for different atoms
 What is the history of the atom? Know the names and order of the models of the
atom.
Chapter 2:
 What are ions?
 How do you calculate concentration in g/L? ppm? m/V%?
 Electrolytes, electrical conductivity, electrolytic dissociation
 What is pH? Where do acids and bases show up on the scale? What are some
common acids and bases? Where is water on the scale? What does alkalinity
mean?
Chapter 3
 What is the law of conservation of energy?
 What is thermal energy? What is heat? What is temperature? What is the
difference between heat and temperature?
 Can you calculate energy efficiency?
Chapter 4
 Physical vs. chemical changes



What is the law of conservation of mass? How do you use it to do calculations
for products or reactants in a problem?
How do you balance a chemical equation?
How can you distinguish between an acid-base neutralization reaction,
combustion, respiration, or photosynthesis?
Chapter 5
 What is static electricity? What are the ways that we can charge objects?
 What is the difference between a conductor and an insulator? What are some
examples of each?
 Know how to perform calculations using Ohm’s law, electrical power, or
electrical energy. The equations will be provided, but you need to know what
each variable is, and the correct units of measurement for each one.
 What is an electrical circuit? What do each of its components do (ie. the
resistor)? Be able to identify them/draw them.
 What are the two types of electrical circuits
 What is the right hand rule, what is it used for, and how do you use it? How do
you draw magnetic field lines on and around a magnet?
Technology
 What are the main types of constraints (see pg. 387)? You should know the
symbol for each one and what it means.
 What are the mechanical properties of materials, and what is a description for
each one?
 What are the main differences between these materials: wood, ceramics, metals,
plastics, and composites? How could you protect these materials from
