Calculate energy kj mol^-1
for h, planck's constant = 6.626 × 10-34 j s.
c = 2.998 × 108 m s-1
a = 6.022 × 1023 mol-1
1 nm = 1 × 10-9 m

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?

In the following redox reaction which is the oxidizing agent and which is the reducing agent? alcl3 + na nacl + al oxidizing agent = reducing agent =
