Some bacteria can use nitrate as an electron acceptor instead of oxygen, reducing it to nitrite. this requires an enzyme called nitrate reductase. write a balanced equation for the oxidation of nadh by nitrate 5 points] calculate the gibbs free energy change under standard state conditions (ago) for the oxidation of nadh by nitrate [tip: you will need to look at table 3.5 in the textbook]. the faraday constant, f, is 96.5 kj/vmol.

Which statement correctly describes potassium iodide, ki? there is a one-to-one ratio of potassium ions to iodide ions. potassium gains electrons and iodine loses electrons during the reaction. the lattice is held together by potassium anions and iodide cations.

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion
