Why Study Chemistry?To be better informedTo be a knowledgeable consumerTo make better decisions for yourself and
societyTo learn problem-solving skillsTo enhance analytical thinkingIt will look great on your transcripts,
provided you earn a good gradeThis class will prepare you for AP Chem
and/or College Chem3
What is Chemistry?Chemistry = the study of matter and the
transformation it undergoesWhat is matter? Matter is anything that has
mass and volume. Your book defines it as The material of the universe
EVERYTHING is a CHEMICALTable salt = sodium chloride, NaClTable sugar = sucrose, C12H22O11
Clothes: Wool, Cotton, PolyesterBody: lipids, Proteins, Carbohydrates,
DNA/RNAYou name it– it’s a chemical!

ChemistryMatter seldom appears or exists in the
form we want!!!Can’t pick a TV or PC from a tree……
Chemistry had to happen!
To clean up the water that we drinkThoughts of chemistry one must think..
5
Chemistry in Action: cooking
Cooking is chemistry in action, with the added benefit that you can eat the results.

ChemistryChemistry is the driving force behind
many “liberal arts”Composition of paints? Colors?Economies of industrial nations
#1 commercial chemical is sulfuric acid– LOTS of uses!
All idustry involves chemical processes
Economies of Developing Nations Agriculture depends on chemicals as fertilizers,
pesticides
Politics and Natural Resources7
The Study of ChemistryChemistry is everywhere!Matter is everywhere!Thus, chemistry matters!
Chemistry involves the study of matter – its properties and behavior.
