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...

In the last lecture (9/28), the Professor mentioned that increasing the intensity of the light source does not remove more electrons from the metal. I also heard that increasing the intensity of the light source actually increases the number of photons but not the amount of energy each photon carrie...
