Chemical Kinetics and Chemical Equilibrium

We've learned about balancing Chemical reactions, but we haven't talked about HOW FAST they are, or, when all is said and done, HOW MUCH of the reactants are left, and HOW MUCH product is produced.

(click on picture to go to the Wikipedia article)

• HOW FAST they run is part of the study of Reaction rate, or CHEMICAL KINETICS.
• HOW MUCH product is produced, and how much of the reactants is left, is part of the study of
• Chemical EQUILIBRIUM.

Start by considering the difference in reaction rates between Iron rusting and Wood burning...

ENDOTHERMIC vs EXOTHERMIC chemical reactions

In endothermic reactions, the products have more energy than the reactants. Heat is absorbed from the surroundings (e.g., a cold pack).
In exothermic reactions, the products have less energy than the reactants. Heat is released to the surroundings (e.g., a heat pack).
Both reactions require some activation energy to begin the reaction.

Read the following section of Chemistry for Dummies, and write a summary of it: http://docs.google.com/Doc?docid=0ARNbGsVH1evCZGQ5MjluM2dfNzRxam13cXJuZw&hl=en , and make a diagram of an exothermic and an endothermic reaction.

Here is an example of the potential energy diagram for the following, exothermic chemical reaction:

CO + NO2 --> CO2 + NO

stoichiometry -- balancing chemical equations using moles from the Chem Collective from Carnegie Mellon University

The following video gives the "big picture" of the mole and its applications.

Blood tests are so complicated?

When you go to get a blood test, for what is the doctor looking? That depends on your age, gender, and symptoms. See the following website for all the details: http://en.wikipedia.org/wiki/Reference_ranges_for_common_blood_tests

Your job: to make a drawing of this graph and find at least 3 differences between men and women. Note! If you're using Google Chrome, you may need the latest plugin (it's safe to install).
You can also go to this site to get a printable version, but you **must** turn in your **own** diagram of this test. http://en.wikipedia.org/wiki/File:Blood_values_for_print.png

The pH of life

Note how narrow is the pH range of life for humans!
