matter is made
of atoms
.
What is an
atom?
What are the three
types of particles
found in an atom
and what is the
charge of each?
Explain the
difference between
an atom, element,
and compound.
What is the difference
between ionic,
covalent, and hydrogen
bonding AND give an
example of each type?
True/False: A
molecule is a
stable group of
elements.
Define solution
and give an
example of a
solution.
Are the hydrogen
bonds between water
molecules adhesion
or cohesion? How do
you know?
What is the difference
between acids and
bases? Use pH and
hydrogen ions in your
answer.
Why is water
sometimes referred
to as the “universal
solvent”?
What three

are found in all
carbohydrates?
Describe the structure
of starch. Is it a
mono/di/poly
saccharide?
Are lipids polar or
nonpolar? Do they
dissolve easily in
water?

difference between
saturated and
unsaturated fats?
What are two
functions of
carbohydrates?

three parts of a
nucleotide?
What are the building
blocks of amino
acids? How many
different types of
building blocks are
there?
What
determines a
protein’s shape
and function?
What do all organic
compounds have in
common? What are
the four main types of
organic compounds?
True/False: Energy exists in
many forms—including light,
heat, chemical energy,
mechanical energy, and
electrical energy- and cannot
be converted from one for to
another.
The starting materials for
chemical reactions are called
_______. The newly formed
substances are called
_______.
What effect do
enzymes have on the
rate of chemical
reactions?
To use a chemical ice pack, a
small bag of solution is broken
open inside the larger bag of
liquid. The two liquids mix and
get cold. What type of reaction is
taking place inside the ice pack?
How do you know?
Explain how enzymes
speed up chemical
reactions.
