BIOL 1201 Lecture : BIOL 1201 Week 2
Document Summary
9/2/2015: for friday: pages 58-77, mastering biology quiz 4, functional groups pre-lec video. Isomers: molecules with the same molecular formula, but a different arrangement of atoms. Gram molecular weight: the mass of a substance equal to its molecular weight in grams, contains a constant number of molecules, avogadro"s number of molecules 6. 02 x 1023. Moles and molar concentrations: 1 mole = the mass of a substance equal to its gram molecular weight, 1 molar solution = a solution containing 1 mole of a substance per 1 liter of solution. Properties of water: cohesive and adhesive, high specific heat, high heat of vaporization, less dense as a solid than a liquid, good solvent for polar molecules. Functional groups: groups of atoms attached to the carbon backbone of organic molecules, cause changes in physical characteristics and chemical properties. 9/4/2015: for next class: read pages 77-91, pre-test 2, pre-lec video on carbohydrates and lipids, check into alpha epsilon delta.
