Any estimate of occupancy less than the previously calculated upper limit would make it more imperative to account for the rapid overall rate observed in terms of a rate constant for the second electron transfer faster than that possible if SQ had to react from the distal domain of the Qo-...
A molecule has an ionizable group with a pKa value of 8. At pH equal to 9.0, estimate roughly how much of the group is deprotonated (expressed as %). A solution of PH 5.0 has what concentration of hydrogen ions? If a solution has an H+ concentration of 0.00000001 moles per l...
Henderson-Hasselbalch equation gives an estimate of the pH of a buffer. You need the pKa of the weak acid or pKb of the weak base, and the concentrations of the weak acid and conjugate base. {eq}\displaystyle pH = pK_a + \log...
To overcome limits of inter-observer variability and limit the time needed for tests, several classification systems that combine various US findings have been developed to estimate the likelihood of malignancy and select nodules for FNA biopsies. The application of these systems, which are endorsed ...
