In many ways, comparing multiple sample means is simply an extension of what we covered last week. Just as we had 3 versions of the t-test (1 sample, 2 sample (with and without equal variance), and paired;
Would you xpect the α-protons of a thioester to have a lower or higher pKa than an ester? Why? Remember the pKa values for the α-protons of several FG's: aldehyde(17), ketone(21), ester(25), amide(35).
You have three 3.0 uF capacitors. Two of the capacitors are in parallel, and this parallel combination is in series with the third capacitor. This capacitor combination is connected across a 30-V battery. Find the charge on each capacitor and the
