A solid oxide fuel cell (or SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel.

They have a neutral oxidation state.

They have a minus two oxidation state.

This is the water oxidation site.

We call that pyruvate oxidation.

There's going to be more oxidation left to do.

This is the oxidation of NADH to NAD plus.

So it has a plus one oxidation state.

So it has a minus two oxidation state.

So it has a plus four oxidation state.

They all have a plus one oxidation state.

And they each have a plus four oxidation state.

So it will have a plus one oxidation state.

And each of them have an oxidation state of two minus.

Oxidation of hydrogen sulfide, sulfide, and elemental sulfur (S) to sulfate (SO42 ).

So that's where the term oxidation comes from.

This is the pyruvate oxidation step that I talked about.

Oxidation of hydrogen sulfide produces elemental sulfur (S8), oxidation state 0.

Oh right! Fuel, fuel!

The filling station. Filling....

Each of them still has a plus one oxidation state.

So nothing from an oxidation reduction point of view happens to the hydrogen.

I touched at the beginning of the video of how a biologist views oxidation.

Copper oxide is a compound from the two elements copper and oxygen.

This occurs by oxidation of water in the case of oxygenic photosynthesis.

The mechanism involves oxidation of the selenol of a selenocysteine residue by hydrogen peroxide.

So, so far we talked a little bit about how a chemist views oxidation.

In purple sulfur bacteria, hydrogen sulfide (H2S) is oxidized to sulfur (S).

So plus six oxygens that have a minus two oxidation state.

I can make it change color without using dye by a process of iron oxidation.

Example of oxidation The formation of iron(III) oxide (rust) through the oxidation of iron 4Fe 3O2 2Fe2O3In the above equation, the iron (Fe) has an oxidation number of 0 before and 3 after the reaction.

Biofuels are fuels that are grown.

(b) Fuel 80.0 0.0

Petrol?

No oxidation state or neutral oxidation state because they're double bonded with oxygen.

So I'll say, for the pyruvate oxidation times two means that we got two NADHs.

Provide a method for determining level of fuel in tank, gauging (the remaining quantity of fuel in the tank must be measured or evaluated).

1. All energy (fuel combustion and fugitive )

So in every situation in glucose, oxygen has a two minus or a minus two oxidation state.

And carbon, since this whole thing is neutral, one would think that carbon would have a neutral oxidation state.

Now, in the citric acid cycle, or in the Krebs cycle, well first we have our pyruvate oxidation.

So this has a one minus because, from an oxidation state point of view, it's taking the electron.

You see, fire made us human fossil fuels made us modern.
