My roomate and I are debating wheather oxygen is released from water when boiled. I say that boiling would not break any oxygen from the H2O molecules. But, I realized maybe it would release the oxygen dissolved in the water, like what fish breath. What is the answer?

you are both correct - the boiling process does not chemically change water into the elements hydrogen and oxygen, but the higher temperature will drive out any dissolved oxygen that was in the water (gases are less soluble in liquids at higher temperatures than lower temperatures)

Dissolved air (including oxygen) comes out when water is boiled. The molecule H2O does not break up.

You are right. Any oxygen being released from the water would be molecular oxygen that had been dissolved in the water rather than from the breakdown of the water molecules (assuming that it's just water and there isn't some catalytic agent in there breaking the water molecules down).

releasing the dissolved O2. This is how you can make crystal clear ice cubes. The cloudiness is the dissolved air.

Photosynthesis... *From the equation of reaction throughout photosynthesis: 6CO2 + 6H2O -> C6H12O6 + 6O2, meaning throughout reaction, vegetation seize in sunlight as this skill invoves in the photolysis of water which reacts with carbon dioxide to yield glucose and oxygen...
