Final answer:
The half-reaction for the strongest reducing agent is: Reducing agent + x e^- → Product species
Step-by-step explanation:
When combining the strongest reducing agent with the strongest oxidizing agent, we can write the half-reaction for the reducing agent as follows:
Reduction half-reaction: Reducing agent + x e^- → Product species
Here, 'x' represents the number of electrons transferred in the reaction. The reducing agent is the species that loses electrons and gets oxidized in the overall reaction, while the oxidizing agent is the species that gains electrons and gets reduced.
