1. Kinetic Molecular Theory

2. Intermolecular Forces-what makes things solid, liquid or gas? 0 London Dispersion Forces-a force between two non-polar molecules during a temporary dipole 0 Hydrogen Bonds-a bond between hydrogen and FON 0 Dipole-Dipole Forces-when the negative end and positive end of two polar molecules are attracted to each other

5. Hydrogen Bonds

6. Dipole-Dipole Forces

7. Kinetic Molecular Theory – Properties of Gases 0 Gas particles do not attract or repel each other 0 Gas particles are smaller than the distances between them 0 Gas particles are in constant, random motion 0 Collisions of gases are elastic (no energy is lost) 0 All gases have the same kinetic energy at a given temperature and pressure

8. Gas Law Program

9. Diffusion-gases mix until they are evenly distributed Effusion- gases escaping through a hole

10. Gas Pressure Units

11. Dalton’s Law of Partial Pressures

12. Which of the following is true? 0 0.80 atm = 0.80 torr 0 4180 mmHg = 557300 0 433 torr = 433 mmHg 0 2.3 atm = 1748 torr

13. The pressure of a mixture of nitrogen, carbon dioxide, and oxygen is 150 kPa. What is the partial pressure of oxygen if the partial pressures of the nitrogen and carbon dioxide are 100 kPA and 24 kPa, respectively?

14. The pressure of the hydrogen and water vapor mixture is 600 mmHg. What is the partial pressure of the hydrogen gas, in atm, if the partial pressure of water vapor is 10.52 mmHg?
