Question
Balance the half reaction as if it were in acid. Next neutralize the H+ by adding OH-.
b)
Complete and balance the following redox reaction in basic solution:
H2O2(aq) + N2H4(aq) ? N2(g) + H2O(l)
First balance the reduction half-reaction. How many OH- ions are there in this half-reaction?
(If the OH- ions are the left side (reactant), write it as a positive number. If they are the right side (product), write it as a negative number.)
n the balanced reaction, how many N2 molecules, OH- ions, and water moleules are there?
a. 1 e-b. 2 e-
c. 3 e-
d. 4 e-
e. 1 OH-
f. 2 OH-
g. 3 OH-
h. 4 OH-
Explanation / Answer
N2H4(l) + 2H2O2(l) ? N2(g) + 4H2O(l)
