What describes the change in oxidation states of the following reaction? 2cl- + f2 > 2f- + cl2 a. cl– reduces to cl and f oxidizes to f–. b. cl– oxidizes to cl and f reduces to f–. d. cl is the reducing agent and f– is the oxidizing agent.

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
