1. Post
a picture of three 3-dimensional Ball and Stick molecular models (choose your
three favorite molecules) that you have created with common items around your
home. Also post a molecular structure image (image from the web, of either a
Kekule Structure or a Ball and Stick Model) and the IUPAC name of the molecule.

Look
over your molecules and the bonding characteristics, how many bonds does each
of the following elements typically have? Carbon? Hydrogen? Oxygen?
Carbon
has 4 bonds, hydrogen has 1 bond, and oxygen has 2 bonds.
4.
What
does IUPAC stand for?
IUPAC stands for International
Union of Pure and Applied Chemistry and it is an international federation of
National Adhering Organizations that represents chemists in individual countries.

As
you explore ingredients, notice how everything around us is made up of
chemicals consisting of atoms bound together into molecules. But what about
companies that claim their products are chemical free! How can this be? Here is
an example:
Do a little web searching and
propose what chemicals are actually in this product. Keep in mind, that everything
at the molecular level is a chemical, whether it be made in nature or in a lab.
Products that claim to be chemical-free are a little misleading. It may
sound like there are no chemicals in them at all; however from my discovery of
chemical compounds and structures in my everyday household items I know this to
be false. These product contain chemicals from naturally occurring chemical
substances (eucalyptus oil, enzymes, etc.) Even though they are natural and
organic ingredients they still are chemicals. When most people think of
chemicals, they think of substances that can harm people and things that we
shouldn’t necessarily be putting in our bodies, but really there are chemicals
all around us and even in naturally occurring substances.
