INTEGRATED SCIENCE 512 Midterm Review Sheet 2012
The exam will cover everything from the beginning of the year (quarters 1 +
2) until now.
The following is a list of the topics we have covered. A periodic table and
table of ions will be provided for you.
CHEMISTRY:
1. What is the difference between a physical and a chemical change?
2. What are protons, electrons, neutrons? Where are they located in the
atom?
3. Be able to find the atomic mass, atomic number, # of protons, electrons
and neutrons of any element on the periodic table. For example, find
all of the above for Calcium:
a.
b.
c.
d.
e.
Atomic number=
Atomic mass=
# of protons=
# of electrons=
# of neutrons=
4. What are the periods and groups in terms of the periodic table?
5. Where are metals? Where are they located on the periodic table?
6. Where are nonmetals? Where are they located on the periodic table?
7. Where are metalloids? Where are they located on the periodic table?
8. Where are the gases located on the table?
9. Where are the liquids and gases located on the table?
10.For each major Family on the periodic table know its location and its
properties: alkali metals, alkaline earth metals, transition metals, ,
halogens & noble gases
11.What is a Bohr model of the atom? Draw Oxygen using the Bohr
model.
12.What is a Lewis dot diagram? Draw Boron and Chlorine using a Lewis
dot diagram.
13.What is an ionic bond? Name 4 properties of ionic compounds. Be able
to identify these bonds. Give 3 examples of substances that form an
ionic bond.

these bonds.
15.What is an isotope? Give an example using carbon.
HYDROCARBONS & COMBUSTION:
16.What is a hydrocarbon?
17. What is the difference between alkanes, alkenes, and alkynes? What
kind of bonds does each have? Which of these is saturated? Which of
these is unsaturated?
18. Draw hexane, hexene and hexyne.
19.What is an isomer? Draw butane and an isomer of butane.
20.What 2 substances are necessary for combustion to occur?

22.What are fossil fuels? Give 2 examples of fossil fuels.
23.What are the products of incomplete combustion? Why does
incomplete combustion occur?
POLYMERS:
24.What is a polymer? Give an example of one natural and one synthetic
polymer.
25.What is a cross-liked polymer? How does cross linking effect polymer
strength?
26.Compare and contrast hydrophobic vs. hydrophilic polymers. What is a
hydrophobic polymer? Give an example. What is a hydrophilic
polymer? Give an example.
27.What are acids and bases?
28.What is neutralization? What substances do you get when you combine
an acid and a base?
29.How do you determine if you have an acid or a base using litmus
paper? reading a pH scale?
30.Calculate the density of different material given their mass and
volume.
