Are changes of state physical or
chemical changes?
Name 4 of the following state changes:
solid liquid
solid  gas
gas  liquid
liquid  solid
liquid  gas
Answer
Definitions 500 Answer
State or phase changes are physical changes
solid liquid = melting
solid  gas = subliming
gas  liquid = condensing
liquid  solid = freezing
liquid  gas = boiling, evaporating
100 Classification of Matter
Give 1 example each of solutions in
which the solvent is in the solid,
liquid and gas phases.
Answer
Classification of Matter 100 Answer
Solid solution = brass, bronze, pewter, or any
alloy
Liquid solution = ethanol in gasoline or
sugar dissolved in water
Gaseous solution = air
200 Classification of Matter
List the three main types of mixtures
in order of increasing particle size.
Answer
Classification of Matter 200 Answer
• Solution – smallest particles – they are
individual ions, atoms or molecules
• Colloid – intermediate size particles
• Suspension – largest size particles – too
heavy to stay mixed without stirring or
shaking
300 Classification of Matter
Explain the difference between
elements and compounds.
Classify each of the following as an
element or compound:
CH4 N2 S8 NH4Cl KI Mo
Answer
Classification of Matter 300 Answer
Elements are composed of only one type of
atom.
Compounds are composed of two or more
different elements.
CH4 NH4Cl and KI are compounds
Mo, S8 and Fe are elements
400 Classification of Matter
Classify each of the following as a
homogeneous mixture, colloid, suspension,
element or compound
Answer
1. Sprite or Sierra Mist soda
2. Gel toothpaste
3. Carbon dioxide gas
4. Latex paint (must be stirred before using)
Classification of Matter 400 Answer
1. Sprite or Sierra Mist soda = solution
2. Gel toothpaste = colloid
3. Carbon dioxide gas = compound
4. Latex paint
(must be stirred before using)
= suspension
500 Classification of Matter
You are shown a bottle containing a
liquid. Describe what you could do to
determine whether it is a homogeneous
mixture, a heterogeneous mixture or a
pure substance. (Your answer must
differentiate between all 3 possibilities)
Answer
Classification of Matter 500 Answer
• Shine a light through it – if it is scatters
light, is cloudy, it is a heterogeneous
mixture.
• If it is clear, heat a sample to boiling. If,
when the liquid boils away, there is a
solid left behind, it was a solution.
• If there is nothing left after boiling at a
constant temperature, it was a pure
substance.

B, Si, Ge, As, Sb, Te, Po
200 Periodic Table
Explain why Ne, He, Xe, Ar, Kr
are in the same column.
What is the name of this group of
elements?
Answer
Periodic Table 200 Answer
• They all have the similar property
of non-reactivity.
• They all have full valence shells.
• The group is called “Noble Gases”

• halogen w/ more protons than Sn = I
500 Periodic Table
• Name the two element rows at the
bottom of the periodic table.
• Give two reasons why these two
rows are located at the bottom of
the table rather than within it.
Answer
Periodic Table 500 Answer
• Lanthanide series (lanthanoids)
• Actinide series (actinoids)
• They are apart from the table because
the elements in the rows have similar
properties to each other but different
valence structures and properties from
the other table groups. Their removal
also makes the table a more manageable
size.
