Chapter 2: Matter.
Monday 10.4.10
Matter

Matter is anything
that has mass and
occupies space.


Air, desk, humans.
Light and sound?
Matter is made up of Elements &
Atoms.



Element- cannot be separated or broken
down into simpler substances.
(Example: Aluminum(Al) , Gold (Au))
Atom- smallest unit of an element that
maintains the properties of the element.
(example: single atom of Aluminum).
Compound- substance made up of
atoms of 2 + different elements.
(Example: Nylon, Aspirin: C6H8O4).
Nylon!

A compound made up
of Carbon, hydrogen,
nitrogen, and oxygen
atoms.
Compounds have unique
properties.
Chemical formulashows how many
atoms of each element
are in a
substance/compound
Chemical formula for Water: H2O
Molecules

Molecules- smallest unit of a substance
that keeps all the physical and chemical
properties of the substance.


When atoms combine and act as a unit!
Can be atoms of the same or different
elements.
Pure Substances vs. Mixtures.

Pure Substancematter with fixed
composition and
definite properties.



Elements and
compounds.
Water: specific amount
of hydrogen and oxygen
atoms!
Chemically combinedhard to separate. Has a
chemical formula!
Mixtures.

Mixturescombinations of
many pure
substances.


Grape juice:
combination of water,
sugar, vitamins, etc.
Can easily be
separated into its
components. No
chemical formula!
Classifying Mixtures.




Heterogeneous mixture- substances are
not uniformly mixed. (Flour in water).
Homogenous mixture- substances are
evenly distributed. (sugar in water,
carbonated beverages).
Miscible- mix evenly together.
Immiscible- do not mix well together (oil
and water).


Exit Ticket: In your notebook write 1-2
sentences to explain why Dr. Pepper is a

substance.


Answer Parts A and B on the small piece of
loose-leaf.

I am checking HW!
2nd Pd: Pre Class: Wednesday
10.6.10

In your notebook write 1-2 sentences to
explain: Why Dr. Pepper is considered a
homogenous mixture but not a pure
substance.

I am checking HW.
Recap: answer in your notebook.

1. Homogenous or Heterogeneous Mixture?


2. Element or Compound?


A. Sea Water B. A pail of sand and water C. Air
D. Chocolate syrup
A. Benzene (C6H6) B. Aluminum (Al) C. Aspirin
(C9H8O4).
3. Pure Substance or Mixture?

A. Salt Water B. Mercury (Hg) C. Ammonia (NH3)
Ch. 2 Section 2: Properties of
Matter.

Physical Properties- observable or
measurable qualities that help identify
substances.



Mass, Volume, Density, State (solid, liquid,
gas), Color, Shape, Texture, Smell.
Melting Point, Boiling Point, Strength, Ability
to conduct electricity.
At sea level, Water boils at 100oC and freezes
at 0oC it has a density of 1.00 g/cm3.
Our good friend Density.


Amount of matter in a certain volume of
substance.
Density=mass/volume


D=m/V (units: g/cm3 or g/mL)
Example: If 10.0 cm3 of ice has a mass of 9.17
g what is the density of the ice? (Pay
attention to Sig. figs!).
Chemical Properties.




Not as easy to observe
as physical properties.
A substance always has
its chemical properties
even when you cannot
observe them.
Identity of the substance
changes (Steel to Rust).
Reactivity, Flammability.
