Find the potential of the cell in which identical iron electrodes are placed into solutions of FeSO4 ofconcentration 1.5 mol/L and 0.15 mol/L.
In this question, why we can asume Fe+2 is involved and not Fe+3?

Answer all question (a-d) thank you Consider a galvanic cell which has an Iron electrode submerged in a Fe(NO3)2 soln. and a Gold electrode submerged in a Au(NO3)3 soln. a) Find the Ecell of this cell under standard conditions: (2pts) Ans: Au3+ (aq) + 3e = Aus) ER 1.50 V + 2e = Fe(s) Er = -0.44 V Fe2+ (aq) b) Write out the balanced net reaction of this cell? (3pts) c) What is the cell potential if the concentration...
*redox reactions in electeochemical cells* c) Fe/0.1 M FeSO4//0.1 M CuSO4/Cu I soaked a porous cup in tap water for a few minutes and then i let it stand in a 100 ml beaker containing 10ml of 0.1 M FeSO4. I added enough 0.1M CuSO4 to the cup until the two liquid levels were the same height. I inserted a zinc strip into the 0.1 M FeSO4 and a shiny copper strip into the 0.1 M CuSO4. I connected the...

A cobalt electrode is placed in 1.00 L of I M CO(NO3)2(aq) and a chromium electrode is placed in 1.00 L of IM Cr(NO3)3(aq). Electrodes are connected by a wire through a voltmeter and the solutions are connected by a salt bridge. (16 points) a. The reduction reaction will be: b. The oxidation reaction will be: c. The...
[ 2 + 2 + 2 + 3 + 3 = 12 marks ] Question 5 (a) Briefly explain why we cannot find simultaneous eigenfunctions of Lt, L, and Lz. An electron in a hydrogen atom is in the n = 2 state. Ignoring spin, write down the list of possible quantum numbers {n, l, m} (b) For two qubits briefly explain, giving examples, the difference between a product state and an entangled state (c) Consider a system of identical...

quantum mechanics question 2m dx2 + W(x). 10.15 Square potential in ld: Swo if |x|< L/2, W(x) = (1) 0 otherwise where the height of the potential Wo can be positive or negative. The corresponding Hamilton operator is I d2 (2) We consider wave functions which are continuous together with their first derivatives. Here we look at scattering states. For these, we need the solutions to Ĥu = Eu with the boundary conditions (k > 0) elkx +R(k)e-ikx if x...
Can you help explaim and solve how to find delta G along with anything related to half-cells I dont even know where to begin, thank you! WILL probe to the piece of metal foil • Read and record the voltape. Do not forget the NOTE : The The filter paper string should be placed in the welis just prior to measuring the voltage 10.

Organic Chemistry Lab question In the experiment we did acid-base extractions to find impurities. The impurity was either benzoic acid (acid) or 4-chloroaniline (base) So in this experiment we did Acid-Base extraction with an unknown compound. So we had an unknown of 0.150 grams and mixed it with 20 mL of diethyl ether. We placed this in a separatory funnel and added 2mL of 1.0 NaOH solution to the separatory funnel and placed the stopper over the top of the...
