Can someone please help me with this question?

Question

Hydrazine is somewhat toxic. Use the half-reactions shown be- low to explain why household bleach (a highly alkaline solution of sodium hypochlorite) should not be mixed with household ammonia or glass cleansers that contain ammonia.

ClO- + H2O + 2e- --> 2OH- + Cl- E°=0.90 V
N2H4 + 2H2O + 2e- --> 2NH3 + 2OH- E°=-0.10 V

Thank you so much! I appreciate your help.

eqn 1 as is. Eo = 0.90 Reverse eqn 2. Eo = 0.10 sum eqn 1 and reverse eqn 2 Eo = 1.00 A + voltage means the products are favored so N2H4 will be produced.
