Activity 3

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.
       Water: H2O
       Carbon Dioxide: CO2
       Methane: CH4

Molecular structure image of Benzene.

2. Post an image from the web, the chemical systematic (IUPAC) name, common name, and the molecule formula for 20 chemicals that you use or eat. Explore the ingredients of things like cosmetics and foods.

3. Look over your molecules and the bonding characteristics, how many bonds does each of the following elements typically have?  Carbon? Hydrogen? Oxygen?
        Carbon: 4
        Hydrogen: 1
        Oxygen: 2
4. What does IUPAC stand for?
       International Union of Pure and Applied Chemistry
5. 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?
        Companies make their products using only natural products that form a bond but do not have any harsh chemicals in it.
