A property is a characteristic or a description of something
(Write down things in purple)
Our properties make us what we are
Some of Malfoy’s properties include

Physical Properties of Matter
A. Things that can be measured with the
metric system
length weight or mass density boiling point freezing point

Mercury (a liquid) is more dense than lead. May be we should say “Get the MERCURY out”, not “Get the lead out.”
Solid water is less dense than liquid water. That’s why ice cubes float in water.
Weight is actually measured in Newtons, not grams.

Sulfur can be identified by its “rotten egg” smell.
Diamond is the hardest mineral we know of.
Halite tastes like salt.

Physical Properties of Matter
D. Describe the phase of matter of the
substance
solid semi-solid (amorphous) liquid gas plasma

Chemical Properties of Matter
A. Describe the way matter interacts
These interactions are sometimes called chemical reactions

Chemical Properties of Matter
In actual chemistry classes, you’ll learn how the electrons of individual atoms of matter combine or transfer to make new compounds.
(aren’t you glad we don’t have to learn that yet?)

Some common chemical properties involving oxygen
B. Oxidation Reactions Oxygen and iron react to
form iron oxide (rust)
Oxygen and hydrogen react to form water
Oxygen and copper react to form copper oxide

Some common examples of chemical properties of acids and bases
C. Acid-Base Reactions
Zinc fizzes in hydrochloric acid
Hydrochloric acid bubbles and fumes on limestone
Vinegar bubbles and foams when in contact with baking soda

Some common examples of chemical properties of electrical reactions
D. Electrical Reactions When electricity is passed
through water and acid, hydrogen and oxygen gasses are released
When electricity is passed though an acid solution with a metal object inside, and a copper diode, the metal becomes “plated” with copper

Some common examples of chemical properties of reactions between
substances
Sodium + chlorine = salt
Silver + sulfur = silver sulfide
(tarnish)
