Trace amounts of rare clements are found within groundwater and are of interest to goochemists. Earopium and terbium are 30 - lanthanide-scries clements that can be measured from the intensity of their fluorescence emittcd when a solution is illuminated with ultraviolet radiation. Certain organic 25 - compounds that bind Eu(III) and Tb(IIl) enhance the cmission, and substances found in natural waters can decrease 20- the cmission. For that reason it is necessary to use standard Eu (II) additions to the sample to correct for such interference. The graph shows the result of such an cxperiment in which the 15- concentration of Eu(III) and Tb(III) was mcasured in a sample of groundwatler. The x-intercept of the Eu(III) plot is 10- -23.1 ml. and the x-intercept of the Th(III) plot is -9.91 ml. In cach case, 10.00 ml. of the sample solution and 15.00 ml. 5- Tb (III) of an organic additive were added to a scries of live 50 ml. volumctric flasks. The standard Eu(lI) or Th(III) solution (0,…

For a tungsten carbene (catalyst) binding to THF (ligand) at 25 oC in per-deuterotoluene solvent, the chemical shift of the unbound catalyst alpha hydrogen was determined to be 794.6 Hz and the peak for the fully bound catalyst alpha hydrogen was observed at 842.4 Hz. Furthermore, the binding constant (or formation constant) Kf was found to be 15.40 M-1. Given the following initial concentrations of catalyst and ligand, calculate the percent THF bound you would expect to see at 25 oC. Record your answer to the nearest tenths of a percent, as a number with no units (Ex. 3.4% ----> enter "3.4") Co = 1.000 M Lo = 0.1000 M

A 10 cm 3 air saturated Fricke dosimetry solution in a 1 cm diameter tube is irradiated for 10 min in a 6~ source of gamma rays. The optical density measured at 304 txm in a 1 cm light path at 30~ was 0.260 after the completion of irradiation and 0.003 before irradiation. (a) What is the total dose in gray absorbed by the solution?(b) If 10 cm 3 of methanol is irradiated in the same tube for the same 10min, what is the absorbed dose in gray. The Z/A for methanol is 0.562 and that for the Fricke dosimeter is 0.553. Explain any assumption you make to solve the problem.
