    These are homework exercises to accompany the Textmap created for Chemistry: A Molecular Approach by Nivaldo Tro. Complementary General Chemistry question banks can be found for other Textmaps and can be accessed here. In addition to these publicly available questions, access to private problems bank for use in exams and homework is available to faculty only on an individual basis; please contact Delmar Larsen for an account with access permission.

    Additional Questions

    Q1

    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)?

    Q1

    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)?

    Q3
