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.
