  1. Q: Electronegativity only affects molecules with what type of bond? A: Nonpolar

  2. Q: What is the word for “equally shared electrons”? A: Oxygen

  3. Q: One of the strongest elements (based on electronegativity) is…. A: delta symbol δ

  4. Q: How is electronegativity represented in a molecule? A: Stronger element

  5. Q: Who becomes negative, the stronger or the weaker element? A: CH4 (methane), H2 (Hydrogen gas)

  6. Q: Give two examples of nonpolar molecules. A: H20 (water), CO2 (carbon dioxide)

  7. Q: Give two examples of polar molecules. A: solution the same throughout

  8. Q: Define homogenous. A: Aqueous because water is the solvent

  9. Q: NaCl+ H2O • What type of solution is this? Why? A: Ionic and polar covalent

  10. Q: What two specific bond types are hydrophilic? A: nonpolar bond

  11. Q: What specific bond type is hydrophobic? A: Hydrophilic because of the charges that make it want to split up

  12. Q: Which, hydrophilic or hydrophobic, mixes with water? Why? A: Hydrogen bond

  13. Q: The bond between the oxygen of one water molecule and the hydrogen of another is what type of bond? A: 4 total, 2 hydrogen and 2 covalent

  14. Q: How many bonds can a single oxygen of water have? What types of bonds are these? A: One is between like substances and the other is between two different substances

  15. Q: What is the difference between cohesion and adhesion? A: Cohesion

  16. Q: Which, cohesion or adhesion, applies to surface tension? A: Amount of heat absorbed/lost for 1g to change 1⁰C

  17. Q: Define and explain specific heat. A: High because it can store and hold on to the heat

  18. Q: Does water have a high or a low specific heat? Explain. A: Short time because it easily gives off the heat, it cannot store it

  19. Q: Does it take a long time or a short time for something with a low specific heat to change in temperature? Why? A: Solid

  20. Q: In what state is water less dense, a solid or a liquid? A: Expands

  21. Q: At temperatures above 4 degrees Celsius, water _______ (expands or contracts) as it warms. A: 0⁰C

  22. Q: At what temperature does water become locked into a crystalline lattice? A: 4 hydrogen bonds

  23. Q: In crystalline lattice, how many bonds does each water molecule have? A: Contracts

  24. Q: From 0 degrees to 4 degrees, water ______ (expands/contracts). A: Hydrogen is very weak and oxygen is very strong. It wants to bond with anything.

  25. Q: Why is water the solvent of life? A: Covalent bond
