CHEMISTRY 1007 Name: ____________________________ Problem Solving Activity #7 October 10 & 11 (can also be turned in by October 16 for participation credit) Given constants: c=2.998x10 8 m/s h=6.626x10 -34 J s 1mile=1.609km Given Formulas: = h/p = h/mv ( x)( p) h/4 1. (5 pts). If n=5, what are the allowed values of the quantum numbers l ? What are the allowed values of m l for each l ? How many orbitals will be in each l subshell? What is the maximum number of electrons that can be in each l subshell? 2. (8%) The letters A through F represent atomic orbitals. Provided the information below, fill in the blanks on the table. Total nodes = n - 1 angular nodes = l radial nodes = n - 1- l Total Nodes Radial Nodes

(3%) Calculate the de Broglie wavelength (in m) of a tennis ball (mass = 54 g) traveling at 110.0 miles per hour. 4. (7%) During photosynthesis, an electron is believed to travel 25Å (1Å = 1x10-10 m) in one picosecond (1ps = 10-12 s). The uncertainty in the time measurement is 0.5 ps. Use the Heisenberg uncertainty principle calculate the uncertainty in the position of the electron at any point during its 25Å journey. (You can assume that the distance, 25Å, and the mass of an electron, 9.109x10-31 kg, are known with a relatively high certainty.)...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
