If there is not enough dissolved oxygen in water then most things will not be able to live in it.
The oxygen atoms left behind from the water molecules join into diatomic oxygen molecules.
fire hazard
Hi
When you burn something without enough oxygen for complete burning, you get incomplete burning; for example, instead of getting carbon dioxide as a combustion product, you could get carbon monoxide.
Usually nothing happens when you add just oxygen to limewater. It is not water-soluble and will not cause a change to its equilibrium.
well, you die
If we do not get enough water we can't live
Soot
You will die
The oxyhaemoglobin will break down and oxygen will release. :)
The concentration of oxygen decrease.
The concentration of oxygen decrease.
Most likely you'll get an explosion that creates carbon dioxide and water. But that will only happen if you get the mixture hot enough or the pressure is high enough.

water is left
Depending on the concentration of the hydrogen peroxide, (if low enough) it will just decompose into water and oxygen gas. If the hydrogen peroxide is high enough in concentration it will just heat up and mix with the water (most likely the first will occur).
If you wear a snorkel with enough oxygen then yes!
