  1. What type of bond holds a water molecule together?
    Polar covalent bond
  2. Why do polar covalent bonds hold a water molecule together?
    Due to an uneven distribution of electrons
  3. What type of bond holds one water molecule to another?
    Hydrogen bond
  4. What's another thing to call water?
    Universal solvent
  5. Is walking on water possible?
    No
  6. Due to an uneven charge distribution h20 is unique because...
    Of cohesion

    • Adhesion
    • And it's a universal solvent (many things dissolve in water)
  7. What is cohesion?
    When things are attracted to each other
  8. What is adhesion?
    When things stick to other things
  9. What does adhesion have I do with water?
    Water has the ability to stick to other surfaces (in a meniscus)
  10. What does cohesion have to do with water?
    Water molecules are attracted to each other
  11. Explain how you can prevent breaking surface tension
    By distributing weight evenly
  12. What is h20 + ice tea mix = iced tea an example of?
    Solution
  13. What is the solvent in the example:
    h20 + ice tea mix = iced tea
    Water
  14. What is the solute in the example :
    h20 + ice tea mix = iced tea
    Iced tea mix
  15. What is a solute?
    The thing that gets dissolved
  16. What is a solvent?
    The things that dissolves
  17. 2 or more elements/compounds mixed together but not chemically combined
    A mixture
  18. Give 3 examples of a mixture
    • Salad
    • Trail mix
    • Oil and vinegar
  19. What do all organic things contain?

  21. Why is carbon a unique element?
    The 4 stable single covalent bonds

    The ability to form chains

    The 2 stable double covalent bonds
  22. How do you find out if something is a carb?
    The H:O ratio is 2:1

    Their structure
  36. Same molecular formula but a different structure is...
    Isomers
  37. What does disaccharides mean?
    Double sugar
  38. 2 monosaccharides chemically bonded together and a H2O molecule is lost is called...
