Welcome to Chemistry 100. The purpose of this course is not to transform you into a chemist or even a scientist, but to inculcate an appreciation of the world around you from a new prospective. The world of chemistry.
Someone once said that there are four kinds of knowledge:
1) All knowlege,
2) the knowledge you know you know, and 3) that body of knowledge you know you don't know.
The fourth catagory of knowledge is my most favorite. It is that knowledge that you don't know you don't know!
This knowledge is the most rewarding; to disocver an area of knowledge that you did not even know existed is
the ultimate quest of mandkind. If you can learn to seek this area of knowledge, you will find life fulfilling and ever a journey filled with reward. The difference between an educated man and a smart man is this thirst to know, a desire to use life to seek and to search for the pure sake of searching. So, let the quest begin!

The course outline is based on chapters 1-10
Chapter 11-20 are supplimental information on various topics. I encourage you to read through some of these chapters as their titles catch your interest!
e.g. Food Chapter 16, Fitness, Chapter 18, and Drugs Chapter 19, etc. Extra credit is availbale for a written report of 500-2000 word and an oral presentation based on chapters 11-20. (see instructor for details)
THE HISTORY OF THE METIC SYSTEM [CLIKCON THE STARS] 2009 December 31 All products sold in Europe (with limited exceptions) will be required to have only SI metric units on their labels. Dual labeling will not be permitted. Implementation of the labeling directive, previously 1999 December 31, was extended by the EU Commission for 10 years, giving more time for companies to comply and for U.S. regulations to allow metric-only labeling on consumer products.

Chapter 2. Law of Definite Proportions
Also called law of constant composition
e.g H2O
•
A compound has the same elements in a certain definite proportion and no other combinations
•
Also implies compounds have constant properties.
Law of Multiple Proportions
Elements might combine in more than one set of proportions. e.g. NO, NO2, N2O5, Always whole number ratios. Dalton's Theory
1.1.
All matter is composed of extremely small particles
–Atoms are indivisible
2. 2.Atoms of a given element are alike but different from atoms of any other element
3.
Compounds are formed when different elements combine in fixed proportions
4.
A chemical reaction involves only a rearrangement of atoms
