3. Look over your molecules and the bonding characteristics, how many bonds does each of the following elements typically have?  Carbon? Hydrogen? Oxygen?

ANSWER:
Carbon: 2 for Carbon Dioxide
Hydrogen: 2 for Water and 2 for Hydrogen Peroxide
Oxygen: 1 for Water and 2 for Hydrogen Peroxide

4. What does IUPAC stand for?
ANSWER:
IUPAC means: 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. Keep in mind, that everything at the molecular level is a chemical, whether it be made in nature or in a lab.

ANSWER:
After reviewing the above listed web address, I have concluded that there is no possible way for any of these so-called "chemical free" products to NOT contain some sort of chemical. Although they may be using safer chemicals, there is still molecular structures being used (i.e. chemical formulas). Therefore, we can assume that all the hype related to "chemical free" products for cleaning is more about environmentally friendly cleaning solutions that include less harmful chemicals.
