Delivery Date
Learning Objectives
- Understand the role of solar photons as an energy source
for chemical reactions in the environment.
- Describe, in general, the dynamics of excited states in
producing products and photo-sensitized reactants.
- Understand the major abiotic chemical reaction pathways
in the environment.
- Describe electrophillic, nucleophillic, hydrolysis and
redox reactions.
- Summarize the basic reactions associated with the
formation of the hole in the ozone layer.
- Summarize the reactions associated with the formation of
acid rock drainage.
