Chemistry for Bioligy (Water and pH (pH (measueres the concentration of …

- - - - Polar - molecule. Each H shares an electron with O. Oxygen
        more attractive to the electrons in the molecule so they hang out
        there causing oxygen side to be negative and the hydrogen side
        to be positive
        
        HIgh specific heat
        
        it takes alot of heat energy to change the temperature of a body of water
        
        capillary action
        
        the ability of water to move up a small diameter tube againsts the force of gravity
        
        High heat of vaporation
        
        when water evaporates it absorbs a lot of het energy, helping cool the object it evaporates from
        
        water as a solvent
        
        water will disolve most polar and ionic suvstances
        
        Surface tension
        
        surface of the body of water will form a film on top because of cohesive properties
        
        adhesion
  - - - Water
        
        1 out of 10,000,000 water molecules ionizes into an OH
- - - - Neutrons
        
        In nucleus, have mass, no charge
      - Electrons
        
        In energy shells, no mass, negative charge
        
        Octect rule: innermost
      - Protons
        
        In nucleus, have mass, positive charge
- - - - Lipids
        
        COntain C, H and O, no set ratio
      - Proteins
      - Carbohydrates
        
        Contain C, H and O; 2:1 ratio H to O
      - Hydrocarbons
        
        Contain C and H
        
        fossilized
      - Monomers vs. polymers
        Monomers are small repeating molecular units that get joined to make complex molecules (polymers)
