A chemical oxygen generator is a device that releases oxygen via a chemical reaction.

So the main tank, the main critical thing, is this oxygen gas supply cylinder we have here.

But, if we only had an oxygen gas supply cylinder we wouldn't be able to go very deep, because we'd run into oxygen toxicity very, very quickly.

But if we only had an oxygen gas supply cylinder, we wouldn't be able to go very deep, because we'd run into oxygen toxicity very quickly.

Animals breathe in oxygen and release carbon dioxide CO2 O2 which is a complete reverse of what the plants were doing.

Hydrox, a gas mixture of hydrogen and oxygen, was used as a breathing gas in very deep diving.

You have muscles contract to bring oxygen, a gas, into your lungs, which is then transferred by your bloodstream to every cell in your body.

In the next video, I'll talk more about our actual circulatory system and how we get the oxygen from the lungs to the rest of the body and how do we get the carbon dioxide from the rest of the body into the lungs?

Now the third thing that happened and also being a significant event, we believe that that oxygen that started to accumulate in the atmosphere reacted with methane in the atmosphere, and methane is a greenhouse gas.

Pure oxygen is mainly used to speed the shallow decompression stops at the end of a military, commercial, or technical dive and is only safe down to a depth of 6 meters (maximum operating depth) before oxygen toxicity sets in.

The first limitation is the oxygen oxygen toxicity.

And now the oxygen began to accumulate.

Gas

Gas.

Gas?

Liquid oxygen

The first limitation is the oxygen oxygen toxicity.

In recent years, oxygen has become available for recreational use in oxygen bars.

Oxygen is reduced.

And oxygen gained hydrogens.

High oxygen content.

I'll write nitrous oxide, it's N2O, this is laughing gas.

You have some oxygen gas or a diatomic oxygen molecule.

Plus one oxygen atom, so I could say one half of molecular oxygen.

Gas, North Sea

Send another pipe down! Right now! It's a gas pocket!

Oxygen saturation is a relative measure of the amount of oxygen that is dissolved or carried in a given medium.

Oxygen has 8 protons.

Oxygen is losing electrons.

Same thing with the oxygen.

And that the oxygen is being reduced.

They need oxygen.

Oxygen is a very electronegative atom.

Oxygen, eventually will make it rust away.

Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.

So I have methane gas plus oxygen gas yields carbon dioxide gas plus water.

Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation in a cryogenic air separation plant.

The primary purpose of the gas system is to provide oxygen, to replenish the oxygen that your body consumes.

So when we have oxygen in the atmosphere we're starting to have an environment where Eucaryotes could at least exist and based on the fossil records on what we looked the DNA has changed over time, I'll do more videos on that, we think that the first Eucaryotes showed up about 2,2 billion years ago, althought there is some debate here, there is some evidence that it might have been a little earlier, a little later,

Is there any gas?

Inside, a teargas cartridge.

And then each oxygen has a two minus.

And hydrogens and oxygen definitely gained hydrogens.

That's what is called the oxygen catastrophy.
