A2 (2pt) Latimer diagram for the reduction of N₂ to NH4* in acidic solution is given below. (a,1pt) Please write out the complete half reaction for each of three adjacent couples. (b,0.5pt) Calculate E°(N₂/NH†). (c,0.5pt) Identify the most difficult step in reducing N₂ to NH4+, and rationalize your answer concisely. -1.87 1.41 1.28 N21 NH3OH N₂Hs + NH

Calculate the E0 for the reaction between S2- and Fe3+ that yields SO42- and Fe2+

What are the oxidation and reduction half-reactions and the balanced overall reaction for each of the following processes:

show full and complete procedure HANDWRITTEN only

Show formulas and calculations. Given a solution with (A) or (B), which solution is more reducing? (A)     solution with 20 mM sufide (HS-; assume S0 as product of sulfide oxidation). (B)     solution with 40 mM Mn2+ (assume MnO2 as product of Mn(II) oxidation).

Redox Problem.Given reaction between dissolved Fe2+ and elemental sulfur (S0) to form hematite (Fe2O3) and sulfide HS-    Fe2+ +  S0 -->  Fe2O3 +  HS- (a) What the oxidant and reductant in this reaction? You must determine half-reactions and balance the reaction.   (b) Is this reaction thermodynamically favorable?   (c) Would this HS- to react readily with Fe2O3 (reverse of the reaction)?

4. When considering the species: K (s), K* (aq), Au (s), Au* (aq), I2 (g), and I- (aq), the strongest reducing agent would be: (a) K (s) (b) K+ (aq) (c) Au (s) (d) Au3+ (aq) (e) I2 (g) (f) I- (aq)

I'm trying to follow the formula: Eocell= Eocathode-Eoanode, does this formula apply to any of these? Why is eq(2) substracted from eq(1)?

Below are the reduction half reactions for chemolithoautotrophic nitrification, where ammonia is a source of electrons and energy and oxygen is the terminal electron acceptor. NO2- + 6e- -> NH4+ (E0 = +0.34 volts) O2 + 4e- ->  2H2O (E0 = +0.82 volts) If you balance and combine the reactions so that 293 moles of NH4+are oxidized to NO2-, how many moles of electrons will be transferred from Nitrogen to Oxygen?

GENERAL CHEMISTRY UPVOTE WILL BE GIVEN. PLEASE WRITE THE COMPLETE SOLUTIONS. BOX THE FINAL ANSWERS.
