The oxidation half-reaction for the given equation is: Fe → Fe2+ + 2e-. This represents the loss of electrons from iron (Fe) to form iron ions (Fe2+).

What is the oxidation half reaction for Fe(s) 2HCl(aq) FeCl2(aq) H2g?

The oxidation half-reaction is: Fe => Fe+3 + 3e-, and the reduction half-reaction is: F2 + 2e- => 2 F-1. For a complete equation, the oxidation half-reaction as written must be multiplied by 2 and added to the reduction half-reaction as written multiplied by 3 to result in an overall reaction of 2 Fe + 3 F2 = 2 FeF3.

Part of a reaction that involves only oxidation or reduction is a?

It's not entirely clear what the question is asking... but oxidation involves the loss of electrons from an atom or ion, and reduction involves the gain of electrons. The other parts of a redox (reduction-oxidation) reaction may involve atoms forming and breaking bonds, but the oxidation or reduction part is just about losing or gaining electrons. You might be talking about what is called a "half-reaction." A half-reaction is the part of the reaction that is only either the oxidation step or the reduction step. Neither is a complete reaction, but put together the two half-reactions give the overall reactions. In the oxidation half-reaction, electrons come out as products, and in the reduction half-reaction electrons go in as reactants. Remember: OIL RIG Oxidation Is Loss; Reduction Is Gain.
