PLEASE ANSWER LAB: MOTION

1. What is the purpose of the lab, the importance of the topic, and the question you are trying to answer?

2. What is your hypothesis (or hypotheses) for this experiment?

3. What methods are you using to test this (or each) hypothesis?

4. Locate the data and observations collected in your lab guide. Eat are the key results? How would you vest summarize the data to relate your findings?

5.Do you have quantitative data (numerical results or calculations)? Do you have qualitative data (written observations and descriptions)? How can you recognize this data for your report?

6. What do the key results indicate?

7. If you constructed graphs, what trends do they indicate in your data?

8. Were there any problems with the experiment or the methods? Did you have any surprising results?

9. What do the results tell you about your hypothesis(es)?

10. How do the data support your claim above?

11. If you could repeat the experiment and make it better, what would you do differently and why?

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.
