fe(+2) + 2e- --> Fe
Balanced chemical equation: Zn (s) + 2HCl (aq) --> ZnCl2 (aq) + H2 (g) Oxidation half-reaction: Zn (s) --> Zn2+ (aq) + 2e- Reduction half-reaction: 2H+ (aq) + 2e- --> H2 (g)
To write an oxidation half reaction using the reduction potential chart, simply reverse the reduction half reaction from the chart. This means changing the sign of the reduction potential value and flipping the direction of the reaction arrow. Remember to balance the reaction by adding any necessary electrons.
The ionic equation for the reduction of copper sulfate (CuSO4) to copper oxide is: Cu^2+ + 2e^- → Cu This equation represents the reduction half-reaction where copper ions (Cu^2+) gain two electrons to form solid copper (Cu). The formation of copper oxide involves further reactions and would require a more comprehensive equation.
The redox reaction is split into its oxidation part and it’s reduction part

Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.

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.
The half equation for the reduction of copper oxide by carbon is: CuO + C -> Cu + CO

The overall redox reaction of Cr2O7 + Br is not a balanced equation. To balance the equation, the half-reactions for the oxidation and reduction of each element need to be determined and balanced first.
