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?  Here is an example:
http://www.naturalhealthcareproducts.com/Cleaning-Products.php
Do a little web searching and propose what chemicals are actually in this product.
The ingredients in the product are natural and are already in the environment.  This would make the product all natural and “chemical free.”  Truly it is not chemical free, but may be natural.
