Blog Post 3, Activity 3

Activity 3:

1. Post a picture of three 3-dimensional Ball and Stick molecular models that you have created with common items around your home. Also post a molecular structure image and the IUPAC name of the molecule.

·         Water

IUPAC Name: Oxidane

 



 

·         Methane

IUPAC Name: Methane

 

 

·         Acetone

IUPAC Name: Propanone

 

 

 

 

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.

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

                Carbon: 4

                Hydrogen: 1

                Oxygen: 2

 

4. What does IUPAC stand for?

IUPAC stands for International Union of Pure and Applied Chemistry. It is an international federation that represents chemists in different countries.

 

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?

 

Although some companies claim that their products are chemical-free, that is not actually the case. When you look at the molecular make-up of anything, there are chemicals in it. The difference in the products that claim to be “chemical free” is that they are made of natural ingredients. This means that the chemicals in these are natural, and not harmful. These products, such as EcoSafe Laundry Powder, contain active ingredients that are able to work on their own. Also often times they are organic and non-toxic, similar to that of the product Miracle II Soap.
