As particle size decreases for HPLC, the required solvent pressure the plate number and the resolution ? increases; increases; degreases decreases; decreases; increases; increases; increases; increases increases; decreases; decreases decreases; increases; increases Normal-phases chromatography uses a stationary phases and a mobile phases. The more the mobile phase becomes, the stronger the eluent strength. Polar; polar; polar nonpolar; nonpolar; polar polar; nonpolar; nonpolar polar; nonpolar; polar nonpolar; polar; nonpolar The half-cells below are connected via a salt-bridge and potentiometer. What is the voltage read by the potentiometer when [Ag^+] = 2.00 M and [V^2+] = 1.50 M? Showing work is NOT REQUIED. 1.912 V -0.326 V -0.313 V 1.937 V 1.924 V Calculate the equilibrium constant for the reaction between Sn metal and Zn^2+ solution. Given these standard reduction potentials: 9.86 times 10^29 1.01 times 10^-21 3.37 times 10^30 3.18 times 10^-11 1.84 times 10^15Explanation / Answer
16.option (C) is correct
17. option (D) is correct
18.E cell = Eo - (0.059/n) log([V2+]/[Ag+]) n = number of electrons transferred = 2
= (EoAg+/Ag - EoV2+/V) - (0.059/n) log([V2+]/[Ag+])
= (0.7993 - (-1.125)) - (0.059/2) x log(1.50/2.00)
= 1.924 V
option (E) is correct
