Biology Unit 2
Water
Cohesion (Water sticks to water, allows for surface tension, strength of hydrogen bonds)
Adhesion (water sticks to other things, allows for water to travel UP a plant)
High specific Heat (Due to H-Bonds, needs to gain or loose LARGE amount of energy to change its temperature)
-
Expands when it freezes (solid form is lighter than liquid form, ice floats and acts as insulator)
Universal Sovulent (capable of dissolving a wide range of substances (solutes) combination = solution
Hydrophobic = water hating (non polar, non charged, do not dissolve in water
-
Amphaphilic = loving both ex: phsospholipids (on the cell, barrier)
Organic Chemistry
Organic: Molecules that contain carbon, hydrogen and usually oxygen ex: methane
Inorganic: molecules that dont have a C and an H ex: Oxygen, Water

-
Carbon Skeleton Diagrams: Each end and corner = Carbon + assume it is hydrogen bond if not specified

-
Polymer: large molcecules made of repeating units (pearl necklace)
Monomers: single small units (3 = polymer, 2 = dimer)
