Question
Part A
Write balanced equation for the anode:
Fe(s)?Fe2+(aq)+2e?
^Correct
Part B
Write balanced equation for the cathode of the following galvanic cell
Fe(s)|Fe2+(aq)||O2(g)|H+(aq),H2O(l)|Pt(s)
Express your answer as a chemical equation. Identify all of the phases in your answer.
Part C
Write balanced equation for overall cell reactions of the following galvanic cell
Fe(s)|Fe2+(aq)||O2(g)|H+(aq),H2O(l)|Pt(s)
Express your answer as a chemical equation. Identify all of the phases in your answer.
Please help with parts b and c, thank you!
Fe(s)?Fe2+(aq)+2e?
Explanation / Answer
B. O2(g) + 4H+(aq) + 4e- -- > 2 H2O(l)
C. 2Fe(s)+ O2(g) + 4H+(aq) -- > 2 H2O(l) + 2Fe2+(aq)
