Set up lab notebook Bring your ion sheet (yellow packet) to lab
Wed is a PLC Day!
Section 17.11. Draw the Lewis Structure of a water molecule2. Define the following:
Ionic molecule Polar covalent molecule Nonpolar covalent molecule
3. Is a water molecule ionic, polar or nonpolar? In your drawing of a water molecule, illustrate why
water is ionic, polar or nonpolar?
4. Define Hydrogen bond. 5. List 3 surface properties of water and include:
how the hydrogen bonding of water causes these properties of water
why these properties are important
6. What is a surfactant?
Section 17.21. Why does water have a high boiling point
and heat of vaporization?2. What is unique about ice (solid water)
compared to other solid substances?• How does this affect the density of ice
compared to liquid water?• Why is this important?
3. In your notes, draw pictures showing the difference in the molecular structures of ice, liquid water and water vapor.
