Write the chemical equation ie formulate the oxidation half

Question

Write the chemical equation, i.e., formulate the oxidation half reaction and the reduction half reaction, and derive the stoichiometric energy generating equation from the half reactions, for a bacterium that:

a. Oxidizes propanol (C₃H₇OH) under aerobic conditions.

b. Oxidizes ferrous iron (F⁺²) to ferric iron (F⁺³) under nitrate reducing conditions, i.e., nitrate reduced to nitrogen gas (NO₃^- -> N₂).
