The element "h2o" is water.
It was one hydrogen atom and two oxygen atoms.
This is completely backwards. The "2" means 2 hydrogens and ONE oxygen. Another term for water is Di-hydrogen-oxide.
Di = Two >
Hydrogen = Hydrogen [duh] >
Oxide = Oxygen

∙ 12y agoAs we know that water's chemical equatoin is H2O, that means in one molecule there is one atom of oxygen. We can't surely tell without a weighting machine, but tje no. of molecules is the amount of oxygen atom.

∙ 8y agoThat depends on how much water you have.
For each molecule of water you have, there is one atom of oxygen.

Why is nonpolar oxygen soluble in polar water?
Because nonpolar oxygen is has a much greater electronegativity and oxygen and water go well.
Why is there more oxygen present in salt water than in fresh?
The amount of oxygen disolved in water may vary. The capacity of water to absorb oxygen (which is not necessarily how much is actually absorbed) depends mainly on the temperature. I don't think the water being salty makes much of a difference.
What happens if there is too much oxygen in seawater?
Oxygen in the water is called "dissolved oxygen" because quite simply it is just that. The air naturally diffuses into the water and can reach equilibrium with the water. It is virtually impossible to get too much dissolved oxygen in the water because the excess will convert back to gas and bubble out of the water like so much soda water when you pour it out of the bottle. This said, there is no concern for too much dissolved oxygen in the water. Concern arises when dissolved oxygen levels get too low. When this happens more sensitive plants and animals become weak or die. As a side note, weather, temperature, and salinity all effect dissolved oxygen levels. Faster moving water contains more dissolved oxygen because it has more contact with the air than still water. Cold, fresh water holds more oxygen than warm or salty water. This would mean a cold, fast moving, fresh water stream or river would contain the highest amounts of dissolved oxygen, and the salinity of the ocean water would not be ideal for holding as much dissolved oxygen.
How much oxygen is used in a reaction where 6g of hydrogen combines with oxygen to form 54g of water?
Imma guess 48.
What osmosis involves . both water and oxygen water but not oxygen oxygen but not water neither water nor oxygen?
Osmosis need not involve either.
What compound of oxygen explains why there is so much oxygen in your bodies?
water
Will oxygen sink or float?
In what? Oxygen is much lighter than water.
Why is nonpolar oxygen soluble in polar water?
Because nonpolar oxygen is has a much greater electronegativity and oxygen and water go well.
How much oxygen does it take to produce water vapor?
The percentage of oxygen in water, vapors or ice is the same.
How much oxygen does hot water have?
zero
Why does fire not burn in water?
Fire feeds on oxygen, and water does not have much of it.
In an electrolysis of water what produces more gas hydrogen or oxygen?
As each water molecule contains one atom of Oxygen and two atoms of Hydrogen you would expect electrolysis of water to produce twice as much Hydrogen as Oxygen.
How much hydrogen and oxygen does water have?
Each molecule of water contains one atom of oxygen and two atoms of hydrogen.
How many oxygen atoms and hydrogen atoms does water have?
It depends on how much water you have!
How much oxgen is in water?
8/9 by weight, of water, is oxygen, as part of the water molecules itself. Apart from that, there may be a variable amount of oxygen gas dissolved in the water. This dissolved oxygen is the only oxygen that can be breathed by certain living creatures, such as fish.
Why is there more oxygen present in salt water than in fresh?
The amount of oxygen disolved in water may vary. The capacity of water to absorb oxygen (which is not necessarily how much is actually absorbed) depends mainly on the temperature. I don't think the water being salty makes much of a difference.
What is the major advantage of air?
The concentration of oxygen in the air is much much higher than in the water. This make obtaining oxygen much easier and strenuous activity (to a level higher than that is water) possible.
