3. Look over your molecules and the bonding characteristics, how many bonds does each of the following elements typically have?  Carbon can form 4.  Hydrogen can form 1.  Oxygen can form two.
4. What does IUPAC stand for? International Union of Pure and applied Chemistry. 8
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:

I think that companies sometimes lie to their consumers, they say that it is chemical free but in reality it is not. Also companies are now trying to use chemicals that are not as harmful to the environment but their product may still include chemicals. Also something may have very few chemicals but not work as great so the consumer is not as happy. Companies are trying to say their product is chemical free but may be a stretch.
