At a certain temperature the rate of this reaction is second order in with a rate constant of : suppose a vessel contains at a concentration of . calculate the concentration of in the vessel seconds later. you may assume no other reaction is important

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?
