Consider the following multistep reaction: A+B→AB(slow)A+B→AB(slow) A+AB→A2B(fast)––––––––––––––––––––– A+AB→A2B(fast)_ 2A+B→A2B(overall)2A+B→A2B(overall) Based on this mechanism, determine the rate law for the overall reaction. Express your answer in standard MasteringChemistry format. For example, if the rate law is k[A]3[B]2k[A]3[B]2 type k*[A]^3*[B]^2.

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?
