If the atmosphere lost all of its oxygen, it is true that human life, and the lives of most organisms, would cease to exist as oxygen is necessary for most life. However, all life would not be eliminated. There are organims (in the domain Archaea) that do not use or need oxygen to survive. These organisms are found in the deep sea by thermal vents and in other extreme habitats. They sythesize food through chemosythesis.
Now, for the information on what the absence of oxygen would mean for the atmosphere and the oceans, I don't know. I need help on that front
Hydrogen! Splitting water into oxygen and hydrogen is achieved by electrolysis (see reaction below). In fact, its the most important source of hydrogen gas.
2H2O(l) → 2H2(g) + O2(g)

No, because water is made up of hydrogen and oxygen. Its formula is H2O. This means it is made up of 2 particles of hydrogen and one of oxygen. If you take away the oxygen then you are left with only hydrogen gas.
Hydrogen as water is made of oxygen and hydrogen.
Venous blood or deoxygenated blood.
No flowing water has more oxygen than stand-still water. I'm not sure why though.
Still water, with no eddies or currents. Turbulent water will mix oxygen and thermal levels. Still water will develop gradients. In still water, above 0°C the surface will be warmest and contain the most oxygen, the bottom will be coldest and contain the least oxygen. In water with atmosheric temperatures below 0°C, the surface will be coldest, being frozen, and temperature either increasing on the way down, or increasing towards the middle, then cooling again, depending on depth. Oxygen levels are generally consistant throughout in bodies of water with a frozen surface.
I think you have misunderstood something. If a leaf is under water, it will still photosynthesise and produce oxygen as long as there is sufficient light. If there is no light it will just respire, consuming oxygen, whether or not it is in water.
No, the water go over to gas form and is still water, but it is not vincible. H2O is water. Hydrogen + oxygen
No, water is a compound of hydrogen and oxygen. And filtered sea water would still have many other impurity's in it as well

Even boiled distilled water will still have oxygen, but the oxygen will not be in elemental form as a dissolved gas.
In a dry environment, the purpose of adding water to the oxygen concentrator is to moisturize the oxygen. Usually, we can add water or no water to the oxygensolve oxygen concentrator, this will not affect the use of the oxygen concentrator. It still needs to be confirmed with the store.
Aquatic animals still breathe oxygen, even if in water. If there's little oxygen dissolved in the water, they will suffocate.
well oxygen dissolves in the water and makes it dissolved oxygen and so they still take in regular oxygen just mixed with water
They use their gills. However, oxygen is still crucial.
No. Boiling water just changes the state of matter. From a liquid to a gas. still 2 hydrogen and still 1 oxygen

The fish hasgills that they use to filter from the water the oxygen they need to as you say "breath" ,so when you put them on land there gills are not working anymore by filtering the water for oxygen because there is no water it's as you know just air (oxygen) so there gills are still trying to work but there is no water to filter oxygen for them.
i think purified water is not a mixture because even when water is purified it still has two hydrogen atoms and 1 oxygen atom so it still remains a compound

Oxygen is less soluble in water at higher temperatures. While the primary transport mechanism for oxygen in the blood is hemoglobin and not water, it is still true that the oxygen has to pass from the hemoglobin into the various fluids of the body in order to be accessible to the cells for metabolism.
