The kp for the reaction below is 1.49 × 108 at 100.0°c:

co(g) + cl2(g) → cocl2(g)

in an equilibrium mixture of the three gases, pco = pcl2 = 2.22 × 10-4 atm. the partial pressure of the product, phosgene (cocl2), is atm.
a) 7.34
b) 3.02 × 1015
c) 3.31 × 10-16
d) 3.31 × 104
e) 6.67 × 1011

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?
