Atomic Structure Homework Problem Set
This problem set was developed by S.E. Van Bramer for Chemistry 145 at Widener University.
- Carbon dioxide (CO2) in the atmosphere acts as a greenhouse gas by absorbing infrared radiation at a wavelength of 15µm. What is the frequency of this radiation (Hz)? What is the energy of a single photon of this radiation (J)? What is the energy of a mole of photons at this wavelength (J mole-1)?
- Ozone (O3) in the stratosphere filters out ultraviolet radiation by absorbing light at a wavelength of 250 nm. What is the frequency of this radiation (Hz)? What is the energy of a single photon of this radiation (J)? What is the energy of a mole of photons at this wavelength (J mole-1)?
- What is the wavelength (nm), frequency (Hz), energy per photon (J) and energy per mole of photons (J mole-1) of the radiation produced by the transition of an electron in hydrogen
