5 Multiple choice questions

  1. ionic and polar substances dissolve in the water.
    hydrophillic vs hydrophobic
  2. Adhesion is the attraction between the unlike substances
    demonstrates capillary action
  3. Strong cohesion [attraction between water molecules]
    occurs because of hydrogen bonding
    High Surface Tension -- creates a water surface that is firm enough to allow insects to walk upon it
  4. the chemical bond that forms between two atoms when one or more electrons are transformed from one atom to anohter.
    happens when the electronegatives differ
    creates ions
  5. changes temperature very slowlyare stable in response to temperature changes of the surrounding air

    *when sweat evaporates, a large amount of heat is taken with it and cools your body

5 True/False questions

  1. moleculesatoms that have positive or negative charges


  2. electronegativitytbe ability of an atom to attract an electron.
    most electronegative: F, O, N


  3. Atomwater expands [because water molecules are kept seperated], and becomes less dense
    floats in liquid water


  4. Hydrogen bondweak bonds between molecules
    form when H+ is in a covalent bond, but is attracted to another molecule [usually with a high electronegativity] in another covalently bonded molecule


  5. nonpolar covalent bondwhen electrons are shared equally
    electronegativities are equal
