Textbook Question
Chapter 17, Problem 58QRT
Hydrazine, N2H4, has been proposed as the fuel in a fuel cell in which oxygen is the oxidizing agent. The reactions are
N2H4(aq) + 4 OH−(aq) → N2(g) + 4 H2O(ℓ) + 4e−
O2(g) + 2 H2O(ℓ) + 4e− → 4 OH−(aq)
- (a) Which reaction occurs at the anode and which at the cathode?
- (b) What is the overall cell reaction?
- (c) If the cell is to produce 0.50 A of current for 50.0 h, calculate what mass in grams of hydrazine must be present.
- (d) Calculate what mass (g) of O2 must be available to react with the mass of N2H4 determined in part (c).

Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask.
