H 2 O special properties sticky! H 2 O-high specific heat- amount of heat that must be absorbed or lost for 1 gram to change temp by 1 degree Celsius Why so high? H-bonding Heat must be absorbed to Heat released when H bonds form break before any change in temp. Upshot: H 2 O is a fairly stable environment Electronegativity: measured as dimensionless pauling units Likeliness to take e- from another element-Scale from .7 to 4.0 (H=2.2, C=2.55, O=3.44, F=3.98) It is a molecular as well as an atomic property Dissociation of water molecules...
