Pt | Cr3+ (2.7010-4 M), Cr2+ (0.500 M) || Pb2+ (0.0710 M) | Pb Consider the following electochemical cell. Calculate the voltage of the cell, Ecell, including the sign.
In acidic solution copper(I) ion is oxidized to copper(II) ion by nitrate ion. I got Cu^+(aq) + NO_3^-(aq) --> Cu^2+(aq) + NO_3^2-(aq)but itswrong
for the E0cell i got 2.35 and for Q i got 8.186 then when i plugged that into the equation i get 2.7101V is that correct? I plugged 1 in for n.
3 Ce4+(aq) + Cr(s) ¨ 3 Ce3+(aq) + Cr3+(aq) What is the emf of this cell when [Ce4+] = 2.9 M, [Ce3+] = 0.11 M, and [Cr3+] = 0.015 M?
If the equilibrium constant for a one-electron redox reaction at 298 K is 7.8 104, calculate the corresponding ÄG° and E°cell. how would i set this problem up?
You can easily do this by using a biology textbook or searching it on google.
then do you subtract the given cell potential from that?
A voltaic cell that uses the reaction Tl3+(aq) + 2 Cr2+(s) ¨ Tl+(aq) + 2 Cr3+(aq) has a measured standard cell potential of +1.19 V. determine Ered for the reduction of Tl3+(aq) to Tl+(aq).
Find the length of the curve over the given interval: x=t+1 y=ln cos(t) for t=0 ---> t=pi/4
1. A plane is headed at 122 degrees with an air speed of 350mph in a wind that is blowing from 38 degrees. Find the ground speed of the plane and the speed of the wind if the actual flight was at 133 degrees. 2. A plane is heading at 20 degrees at 300mph If a wind is blowing f...
