Just because an element is part of a molecule doesn't make it a part of something else. Air is mostly nitrogen, not oxygen. You can't breathe pure water vapor, it's not air. Internal combustion engines cannot burn water vapor. If you can figure out how to burn water you'll be a billionaire and save the planet.
