Hailie Armstrong Ms. Gorges U4 L8 Chemistry 11/19/14 Modeling Molecules Introduction: You can represent a molecule two-dimensionally‚ as a structural formula or electron dot structure. Although such models are useful in certain contexts‚ they do not accurately represent bond angles between atoms or shapes of molecules. In this activity‚ you will construct three-dimensional models of several molecules. You will use electron dot structures and structural formulas to inform how you construct the three-dimensional

ORGANIC MACROMOLECULES 1. What is a polymer? 2. Man-made polymers have been studied since 1832. Today‚ the polymer industry has grown to be larger than the aluminum‚ copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Give examples where polymers are applied in each of these categories: a) Agriculture b) Medicine c) Consumer Science
