Since this answer was first posted in chemistry, you may want to follow the nearby link to an excellent paper on what happens when a wine oxidizes. Wine lovers may read on. Unless we're talking about Sherry, Madeira, or perhaps Marsalla, the only role oxidation plays in wine making is that of the villain. Oxidation (which is not the same thing as oxygenation, which is desirable in the early stages of beer brewing) is almost always bad. Notable exceptions are in the making of some Sherry and Madeira, the latter being cooked a bit to cause oxidation of the wine. Oxidation imparts a taste that is difficult to describe but is, curiously, desirable in some sweeter Sherry wines and in Madeira. Not too surprisingly, oxidation in other wines is also called, somewhat euphemistically, "maderization." Once you've tasted Sherry and Madeira, you will be able to recognize the notes and tastes of undesirable oxidation in other wines (and even some liqueurs). Another sign is an unattractive darkening of the wine. Oxidation is not as offensive in sweet wines, but if you have a dry wine that has oxidized, well, then the only recourse is to invert the open bottle over the kitchen sink.

If wine that's stored in barrels after fermentation is exposed to too much air this could turn the wine into?
ideally just oxidised wine, but in most cases the wine will be infected by a bacteria that will turn the alcohol in the wine into acetic acid. Basically you end up with vinegar.
What happens to rubidium when it is exposed to air?
It is oxidised, forming principally Rb2O. If the air is damp then a hydrolysis may occur, liberating hydrogen and forming RbOH and possibly a fire, Rb is quite reactive!
What happens to oxygen level at high altitudes?
The oxygen level remains about the same, but the density of the air is reduced.
What happens when coal is burn without oxygen?
Coal cannot burn without oxygen.
What substance is formed when alcohol is oxidised by the air?
Ethanoic acid (common name is acetic acid)
What does wine go sour in air?
because it gets oxidised when it gets contact with air.
Is oxidised wine injurious to health?
No oxidised wine will not harm you. Some cultures even enjoy oxidised wines because they take on a sherry like flavor. When a wine oxidises it just means that unnecessary air has entered into the bottle. This can happen many ways; cork has come slightly lose and air has entered the bottle or, the bottles haven't been properly stored.

What happens to an iron nail when it rust?
The iron is oxidised by oxygen in the air. This process is catalysed (faster) in the presence of water and salt. Fe(s) + O2(g) --> Fe2O3(s) (rust)
What happens to rubidium when it is exposed to air?
It is oxidised, forming principally Rb2O. If the air is damp then a hydrolysis may occur, liberating hydrogen and forming RbOH and possibly a fire, Rb is quite reactive!
Steel wool rusts if you use it and leave it on the edge of the sink what must steel wool be made of in order to see this reaction?
Any metal which can get oxidised in the presence of oxygen from the air and water.
What happens when there is less oxygen in air?
Everyone will suffocate and die..
What happens when substances burn in air?
Oxygen is used up.
What happens to oxygen level at high altitudes?
The oxygen level remains about the same, but the density of the air is reduced.
What use does a wine breather provide?
As a wine is exposed to oxygen, it releases additional aromas and flavors. This can enhance a fine wine or expose flaws in a cheaper version. When a wine bottle is uncorked, there is only a small amount of surface area exposed to the air. Using a wine breather or wine aerator, the whole amount of the wine will be exposed to air and therefore reach a more mature flavor.
If oxygen is removed from a sample of air as iron rusts what happens to the total pressure of the air?
it decreases
What happens to Uranium at 20 degrees Celsius?
Surface oxydation with the oxygen from the air.
