$$ \begin{align} \ce{H2S (aq) + NH3 (aq) &→ NH4+ (aq) + HS- (aq)}\tag{1}\\ \ce{Pb(s) + 2 FeCl3 (aq) &→ 2FeCl2 (aq) + PbCl2 (aq)}\tag{2} \end{align} $$
Which of the following statements correctly describes both of the equations above?
A. Both equations represent redox reactions.
B. Equation 1 represents a redox reaction but equation 2 does not.
C. Equation 2 represents a redox reaction but equation 1 does not.
D. Neither equation represents a redox reaction.
The answer key says that the correct answer is C. I picked A. But in equation 1, $\ce{H2S}$ donates a hydrogen to the $\ce{NH3}$ which would mean it's a redox as well. Both equations had donations and acceptances so I really don't understand why equation 1 is not a redox reaction.
