Molecules


Hey Class!!

As we finish talking about the smallest particles that make up matter, we begin talking about the substances that are made from different combinations of atoms. A molecule is a combination of at least two atoms that form a strong chemical bond. A molecule might consist of a single element (O2) or of different elements (H2O).

Go to the following website: All About Molecules

Read the whole introduction to what a molecule is.

Then, pick one molecule and, in your own words, describe the molecule in a post.

Carbon dioxide is in less then 1 % of the air on the earth,It is also know as CO2,it consists of one black carbon atom,and two red oxygen atoms.It is very important to life. And has alot of energy molecules

Aspirin

Chemists learned to make aspirin by studying a similar pain-killing molecule discovered in willow trees.
9 black carbon atoms
8 white hydrogen atoms
4 red oxygen atoms

nicotine is in tobacco and cigarettes. it is a poison and an addictive substance. in our brains it makes nerve cells activate. named from the tobacco plant nicotiana tabacum. 10 carbon 14 oxygen and 2 nitrogen atoms.

Carbon dioxide is very little in supply but is necessary for photosynthesis, thus is a necessity for air, and thus most life. Carbon dioxide is very dangerous to breathe in though, as it is toxic in large quantities. It is in beer and sparkling beverages because of fermentation, and is one of the many reasons too much beer can lead to your ultimate demise.

Also, if there was no carbon dioxide, there would be no carbohydrates. I don't know about you, but I couldn't live without my french fries.

CO2
1 black carbon atom
2 red oxygen atoms
