Note: Please be careful with the units and measurements in your calculations. And also, the question in section "a" is that the arrow down icon has two choices, "canode or anode." Thank you. Thank you so much!
Hydrazine, N2H4, has been proposed as the fuel in a fuel cell in which oxygen is the oxidizing agent. The reactions are as foll N2H4(aq)+4OH(aq)N2(g)+4H2O(l)+4eO2(g)+2H2O(l)+4e4OH(aq) (a) Which reaction occurs at the anode and which at the cathode? N2H4(aq)+4OH(aq)N2(g)+4H2O(l)+4eO2(g)+2H2O(l)+4e4OH(aq) (b) What is the net cell reaction? (Include states of matter in your answer. Leave any unneeded answer blanks empty.) (c) If the cell is to produce 0.44A of current for 48.0h, what mass in grams of hydrazine must be present? g (d) What mass in grams of O2 must be available to react with the mass of N2H4 determined in part (c)? gStep by Step Solution
