Final answer:
The reducing agent in the reaction is Al(s) and the oxidizing agent is F2(g).
Step-by-step explanation:
In the given redox reaction, Al(s) + F2(g) → A3+ + F-(aq), the reducing agent is Al(s) and the oxidizing agent is F2(g). The reducing agent is the reactant that undergoes oxidation and loses electrons, while the oxidizing agent is the reactant that undergoes reduction and gains electrons.
