what are the other acceptors other than O2?

Nitrate, Sulfate, Carbon Dioxide, Ferric Iron.

What is typically a donor

Food.

In C₂H₆O + NO₃^- + H⁺ → CO₂ + N₂ + H₂O … Who is the donor and who is the acceptor

Nitrate, NO₃^- is the acceptor while C₂H₆O is the donor.

In Fe³⁺ + e^- → Fe²⁺ … Who is the donor and who is the acceptor

Ferric iron, Fe³⁺ is the acceptor while e^- is the donor.

What is the name for this reaction: Fe³⁺ + e^- → Fe²⁺

Iron Reduction

What is the name of Fe²⁺

Ferrous Iron

In SO₄^2- + 8e^- + 10H⁺ → H₂S + 4H₂O who is the donor and who is the acceptor

Sulfate, SO₄^2- is the acceptor while e^- is the donor.

What is the name for this reduction: SO₄^2- + 8e^- + 10H⁺ → H₂S + 4H₂O

Sulfate reduction or Sulfido genesis

In CO₂ + 8e^- + 8H⁺ → CH₄ + 2H₂O Who is the donor and who is the acceptor

Carbon Dioxide, CO₂ is the acceptor while e^- is the donor.

What are the other types of electron donors?

Chlorinated organic compounds, like chloroform.

What is hydro genesis

When a halogenated organic compound (one or more hydrogens replaced by a halogen: F,Cl,Br) is used as an e^- acceptor

What is it called when microbes can grow as a result of hydrogenesis?

Organohalide Respiration

Is Organohalide Respiration good?

Yes, turns chlorinated solvents into less harmful compounds.

If there is a presence of O₂ and it is an e^- acceptor, what is it called?

Aerobic.

If there is no O₂ and you need an e^- acceptor, what is that called?

Anaerobic.

What is the K equilibrium equation? What are the units used

K = [C]^c[D]^d / [A]^a[B]^b …. units are in M (mol/L)
