Activity Three!

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, H20: 

Methane, CH4:  

 

 

Ethanol, C2H50H: 

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.

-Sodium Chloride, Salt, NaCl:  

-Sodium Bicarbonate, Baking Soda, NaHCO3: 

-Silicon Dioxide, Glass, SiO2:

-Sodium Hypochlorite, Bleach, NaOCl:

-Sodium Hydroxide, Drano, HaOH:

-Ethanol, Alcohol, C2H60:

-Acetylsalicylic Acid, Aspirin, C9H804:

-Calcium Carbonate, Chalk, CaCO3:

-Magnesium Hydroxide, Milk, Mg(0H)2:

-Silicon Dioxide, Silica, SiO4:

-Ethylene Glycol, Antifreeze, C2H602:

-Water Oxidane, Water, H20:

-Aluminum, Aluminum foil, Al:

-Acetic Acid, Vinegar, HC2H302:

-Ammonium Chloride, Shampoo, NH4Cl:

-Qxybenzone, Sunscreen, C14H1203:

-Chalcopyrite, Fool’s Gold, CuFeS2:

-Hydrogen Peroxide, Hydrogen Peroxide, H202:

-Propane, Propane Gas, C3H8:

-Butane, Lighter Fluid, C4H10:

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

Hydrogen typically needs 1 bond because it has 1 electron in the outer ring.  Oxygen typically needs 2 bonds because it has 6 electrons in the outer ring.  Carbon typically needs 4 bonds because it has 4 electrons in the outer ring.

4. What does IUPAC stand for?

IUPAC stands for the 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.

There is nothing that is completely free of chemicals because everything is made out of some chemical bond like water.  This is seen in the Green Aussie Cleaner that is said to be chemical free.  A basic thing like water that is present in this material is a chemical bond which makes their title of chemical free false advertising.
