Non-polar covalent- equal sharing Water and it's Chemistry H slight positive O slight negative Hydrogen Bonding between water molecules Hydrogen bonds accur with water molecules and organic molecules Cohesion/Adhesion Great solvent due to polarity High specific heat (high capacity)- because of this water takes a lot more energy to heat up and retains it's heat after heat source is gone. amount of heat to change 1g by 1 degree Celsius High heat of vaporization Waters density decreases as it freezes due to hydrogen bonding Water ionization- H2O= +H (+) -OH Mole- the amount of a compound(g) equivalent to it's molecular weight Hydrogen ion concentration= Acid rain- CO2 + H2O = H2CO3 coal burning-SO2 Pages= 37-45 TEST 2 Notes Cytoskeleton-smallest to largest Actin Helps entire cell or parts to move muscle contraction Help stabilize cell shape cell division microvili- dynamic, flexible Intermediate fibers Long lasting, Durable karatin ex. hair, fingernails, hooves Microtubes hollow alpha and beta subunits of. ..... Ex. red blood cells are shaped like filled donuts because that is the necessary shape
