Since h2o (water) has oxygen why can't we breath in it?

In the case of hydrogen and oxygen gas, if you react them together one way you get liquid water (H2O). The reason we cannot breathe liquid water is because the oxygen used to make the water is bound to two hydrogen atoms, and we cannot breathe the resulting liquid. The oxygen is useless to our lungs in this form.

Also. Humans cannot breathe underwater because our lungs do not have enough surface area to absorb enough oxygen from water, and the lining in our lungs is adapted to handle air rather than water. Answer my question? :) http://answers.yahoo.com/question/index;_ylt=Ai87R...

The Oxygen in H2O is bonded (very strongly) to the two hydrogens, and so cannot be inhaled.

Dissolved oxygen in water can be used for breathing - but only if you have gills, which are a specific adaptation necessary for breathing underwater.

When Oxygen bonds with Hydrogen to form water it creates a different chemical compound. Our lungs can't break the bonds to use the Oxygen. So what ends up happening if you try to breathe underwater is the water fills your lungs and doesn't let any Oxygen to get in.

The answer is in the equation, because there is 2 hydrogen and 1 oxygen bonding it will create water which is liquid but as we all now we only breath in gases not liquid. I.e you don't only breath in oxygen you also breath in nitrogen, hydrogen and other gases but they are inhaled in small amount so they won't do any harm to the body.

Simple answer is:

Because you dont have gills.

nicely, once you swallow water, it is going into the tummy yet gasoline substitute happens in the lungs, so it is not any longer likely that eating water could right now develop productiveness of respiratory.

Water molecules are too heavy to inhale.
