Activity 3

Activity 3

Questions/Activities:

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
IUPAC Name: Dihydrogen Oxide



Carbon Dioxide: CO2
IUPAC Name: Carbon Dioxide


Salt: NaCl
IUPAC Name: Sodium Chloride




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.

1. Peroxide: C2O2: Dihydrogen Dioxide

2. Salt: NaCl: Sodium Chloride

3. Vitamin C: C6H8O6: 1,2 dihydroxyethyl 3,4 dihydroxyfuran

4. Propane gas: C3H8: Propane

5. Drain Cleaner: NaOH: Sodium Hydroxide

6. Aluminum Foil: Al: Aluminum

7. Baking soda: Sodium Bicarbonate: NaHCO3

8. Sugar from milk : C12H22O11: β-D-galactopyranosyl-(1-4)-D-glucose

9. Glycerin: C3H8O3: Propan 1,2,3-triol

10. Eggshell:CaCO3:Calcium Carbonate

11. Sodium Fluoride: NaF: Sodium Fluoride

12. Caffeine: C8H10N4O2: 1,3,7 trimethyl 1H purine 2,6(2H,7H) dione

13. Boric Acid:H3BO3: Insecticide

14. Household Cleaner (Ammonia): NH3: Azane

15. Water: H2O: Water Oxidane

16. Lighter Fluid: C4H10: Butane

17. Laundry Detergent: Na2[B4O5(OH)4] 8H2O: Sodium tetraborate dechydrate

18. Nail Polish Remover: CH3COCH3:Acetone

19. Corn syrup: C6H12O6: Fructose

20. Bleach: NaOCl: Sodium Hypochlorite

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

Carbon: 4
Hydrogen: 1
Oxygen: 2

4. What does IUPAC stand for?

“The IUPAC is the International Union of Pure and Applied Chemistry. It is an international scientific organization, not affiliated with any government. The IUPAC strives to advance chemistry, in part by setting global standards for names, symbols, and units.”

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?

“Almost nothing is chemical free. All matter is made up of chemicals (elements). And all products are made up of matter. Water is a chemical (2 parts Hydrogen, 1 part Oxygen). Vinegar is a chemical. The only things that are not chemical are things like light, electricity, magnetism, or subatomic particles. These are unlikely to be the composition of your “chemical free” cosmetic or cleaning product.”
