which of these is an oxidation half - reaction?\no v^{3+}+e^{-}→v^{2+}\no fe→fe^{3+}+3e^{-}\no c^{4+}+2e^{-}→c^{2+}\ndone

Answer

Brief Explanations:

Oxidation is the loss of electrons. In the reaction $Fe \rightarrow Fe^{3+}+3e^-$, iron loses 3 electrons. In the other reactions, species gain electrons which is reduction.

Answer:

Fe → Fe³⁺ + 3e⁻
