Midterm winter 2013 question #4
For question #4 you are asked to calculate the work from B to C (the process is reversible, isothermal expansion at 3045K). Both volume (L) and pressure (atm) are changing. What equation would you use to calculate work: w=-nRTln(v2/v1) or w=-nRTln(p1/p2)?

Quiz 1 prep. #8-Limiting reagent [ENDORSED]
In question #8 in Quiz 1 Preparation, the question asks you "to determine the limiting reagent if 21.4g NH3 is reacted with 42.5g 02." I converted the 21.4g of NH3 into moles and I got 1.26 mol NH3. I also did the same for O2 and I got 1.33 mol O2. I thought that the 1.26 mol NH3 was the l...
