Density
All _______________ has _______________ and _______________. You can
_______________ the _______________ of an object by using the following
_______________:
Density = Mass ➗ Volume
As an example, suppose that you have a sample of the mineral talc. Your sample has a
mass of 26 g and a volume of 10 cm3. It you divide 26 g by 10 cm3, you will get a density of 2.6
g/cm3.
_______________ is a _______________ of minerals that _______________ changes.
For this reason, _______________ can be used to help _______________ minerals. Density is
_______________ in _______________ per cubic _______________, or g/cm3. Most
_______________ have a _______________ that measures between _____ and _____ g/cm3.

Magnetism
_______________ is displayed when _______________ made of _______________ ,
nickel, or cobalt are _______________ to a _______________. _______________, which is an
alloy of _______________, also shows _______________. Magnetite is a _______________
that _______________ iron. If you held a _______________ chunk of magnetite near a
_______________, the magnetite would be _______________ to the _______________.
Magnetite can also sometimes _______________ as a _______________ itself. Magnetite
_______________ the _______________ of magnetism.
2. EXPLAIN: How could you use a magnet to determine if an unknown mineral is magnetite?

The Acid Test
Some _______________ contain calcium carbonate (CaCO3). Knowing that a mineral
_______________ this compound can _______________ you _______________ the mineral.
To _______________ for calcium carbonate in a mineral, you place a _______________ of a
weak _______________ on a _______________ piece of the _______________. If the
_______________ of the mineral _______________, the mineral _______________ calcium
carbonate. This is the _______________ test. Calcite and dolomite are _______________
minerals that _______________ calcium carbonate.
