An example of a balanced equation representing an oxidation-reduction reaction is:
2H2 + O2 -> 2H2O
In this reaction, hydrogen is oxidized (loses electrons) to form water, while oxygen is reduced (gains electrons).
the question is:
C2H4 + MnO4- + H+ -> CO2 + Mn2+ + H2O
the answer is:
C2H4 -> CO2

The oxidation half-reaction includes only the species that is oxidized. Since the oxidation number of C goes from -2 to +4, it is oxidized.
The redox reaction is split into its oxidation part and it’s reduction part
The following information needs to be given to know the answer. Without this a person will not know what the oxidation reaction for it would be.
The coefficients in a balanced chemical equation show the proportions of the reactants and products involved in a chemical reaction. Each coefficient represents the number of moles of each substance in the reaction.
the coefficients of a balanced reaction
The balanced half equation for bromine and potassium iodide is: Br2 + 2e- -> 2Br- This equation represents the reduction half-reaction for bromine.
The balanced equation for the reaction of iron with chlorine is: Fe + Cl2 -> FeCl3.
The balanced chemical equation for the reaction of sulfur dioxide with water is: SO2 + H2O → H2SO3
