# Learning Outcomes for Chapter 2

To master the material in this chapter, a student needs to know...

1. the 3 primary components and their percentages of dry air
2. how those percentages change when humid air is used
3. what the major layers of our atmosphere are named and their order relative to the earth's surface
4. what the physical description and definition of pressure is
5. each of the major gas laws and how they combine to give the ideal gas law
6. how to do the myriad calculations relating to the gas law values - specifically, calculating P, V, T, and n according to the ideal gas law and associated laws
7. how to convert pressure of a gas into number (mole) density
8. what partial pressure is and how to calculate it.
9. how to get mole fraction from partial pressure and total pressure and vice versa
10. how to work stoichiometry problems with gases as reactants and/or products
11. how to use the pressure and identity of a gas to calculate its mass density
12. how to convert mass density and pressure into the molecular weight of a gas
13. the 6 primary pollutants in our air - know names and formulas and/or abbreviations for them
14. the primary sources/causes of those pollutants
15. what methods are in place to help curb the amounts of these pollutants in air
16. the names, formulas, and physical state of the first 10 alkanes
17. anything else we learned and did in class, on HW, that I might have forgot here
