Questions

1. 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. Perhaps explore the ingredients of things like cosmetics, foods and/or automotive product.

Sodium Chloride -Table Salt  – NaCl

Ethyl Alcohol – Mouthwash – CH3CH2OH

Sodium Bicarbonate- Baking Powder- NaHCO₃

Acetic acid or Ethanoic acid- Vinegar- C₂H₄O₂

Sucrose- Sugar- C12H22O11

Calcium Carbonate- Chalk- CaCO3

Ethanol- Alcohol- C2H6O

Graphite (Carbon)- Black Lead- C

Sodium Hypochlorite- Bleach- NaOCl

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

• Hydrogen- 1
• Carbon- 4
• Oxygen- 2

3. What does IUPAC stand for?

• International Union of Pure and Applied Chemistry

4. 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?

• The claim that companies make that their products are “chemical free” is almost impossible because everything is a chemical at the molecular level. If you think about it vinegar is a chemical, kosher salt is a chemical, and baking soda is also a chemical. The reason companies label their products as chemical free is solely a marketing ploy to make themselves look better than competitors. The companies that say they are chemical free are most likely using more natural chemicals instead of chemicals that are formed in laboratories.

5. Also do a little searching on the web and share on your blog how many chemicals are typically found in things like coffee, milk, beer or whiskey?

• Milk- There can be as many as 20 different chemicals found in your milk such as painkillers, antibiotics and growth hormones. Cows milk contains the highest levels of chemicals when tested with goats milk and breastmilk.
