Is it true that Oxygen is what destroys both the hammer and the nail. If this is true, is (O2) the thing that makes our very own bodies tissue become weak the more we are exposed to it [O2]? ....Is there a plausible, serious way to reduce or avoid exposure to this while still being able maintain a normal existence?

Oxygen, like a lot of substances our body needs, can be harmful in large quantities.  This is partly due to its highly electromagnetic and hydrophyllic nature.  As any patient that has been on oxygen therapy can tell you, your body is "set" to use a certain percentage of oxygen in the air we breathe.  If we get used to a higher amount, and then this amount is depreived, we feel light-headed and weak.  This is because at higher levels of oxygen, our lungs become accustomed to a smaller amount of effort to extract and use the oxygen from the air.  \n\nOxygen's corrosive nature is not found in the O2 form however, but the O and O3 (ozone) forms.  This is because oxygen is most stable in the O2 form.  This is where oxygen "wants" to be.  The O3 and O forms are unstable, and prone to reactions.    \n\n"Oxygen can be toxic at elevated partial pressures (i.e. high relative concentrations). This is important in some forms of scuba diving, such as with a rebreather.\n\nCertain derivatives of oxygen, such as ozone (O3), singlet oxygen, hydrogen peroxide, hydroxyl radicals and superoxide, are also highly toxic. The body has developed mechanisms to protect against these toxic compounds. For instance, the naturally-occurring glutathione can act as an antioxidant, as can bilirubin which is normally a breakdown product of hemoglobin. To protect against the destructive nature of peroxides, nearly every organism on earth has developed some form of the enzyme catalase, which very quickly disproportionates peroxide into water and dioxygen.\n\nHighly concentrated sources of oxygen promote rapid combustion and therefore are fire and explosion hazards in the presence of fuels. The fire that killed the Apollo 1 crew on a test launchpad spread so rapidly because the capsule was pressurized with pure oxygen as would be usual in an actual flight, but to maintain positive pressure in the capsule, this was at slightly more than atmospheric pressure instead of the 1/3 pressure that would be used in flight. (See partial pressure.) Similar hazards also apply to compounds of oxygen with a high oxidative potential, such as chlorates, perchlorates, and dichromates; they also can often cause chemical burns.\n\nOxygen derivatives are prone to form free radicals, especially in metabolic processes. Because they can cause severe damage to cells and their DNA, they form part of theories of carcinogenesis and aging." (Wikipedia 2006)\n\n"Oxygen is the most abundant element on this planet. The earth's crust is 46.6% oxygen by weight, the oceans are 86% oxygen by weight, and the atmosphere is 21% oxygen by volume. The name oxygen comes from the Greek stems oxys, "acid," and gennan, "to form or generate." Thus, oxygen literally means "acid former." This name was introduced by Lavoisier, who noticed that compounds rich in oxygen, such as SO2 and P4O10, dissolve in water to give acids.\n\n"Fluorine is the only element that is more electronegative than oxygen. As a result, oxygen gains electrons in virtually all its chemical reactions. Each O2 molecule must gain four electrons to satisfy the octets of the two oxygen atoms." ("Chemistry of Oxygen" - Bodner Research Group)

... because it is unhealthy! \n\nyour nails contains all the bad bad harmful germs or bacteria....\nNOW, imagine you chew and ''eat'' it!! \nit's so not good!

Nail polish remover ... it's probably going to burn, but since it's used on skin around fingernails, it shouldn't do any long-term damage.\n\nAnd I don't even want to know why you need the answer to this question.

Air is oxygen and nitrogen and that those pressures would react to form nitrous oxide or something along those lines.  People have accidentally created very high pressures, for example in welding one can trap high pressure gas in the weld which can cause the weld to crack.  Another case is certain metals when used in nuclear reactors form gas in the millions of psi range (but in very tiny amounts), again leading to cracking.

Higher partial pressure of O2 in atmosphere that that present in the blood.\n\nRemember, blood in the lungs will be DEOXYGENATED!

Oxygen deprivation can cause headaches, severe, debilitating headaches. Oxygen levels below 90 are generally unacceptable and seriously reduces oxygen getting to the brain, causing headaches and eventually death. Mine did a nosedive below 60 before a medical professional realized what was causing my headaches and lethargy. There are quacks and there are doctors!!! I finally got a real doctor.\n\nPlease see a doctor immediately and ask for a blood oxygen measurement with an oximeter. If that's not the problem, sleep apnea is another real possibility, often requiring testing by a sleep disorders lab. \n\nI, too, hate having to take medication and use oxygen equipment, but it's more desirable than those awful headaches.

Without oxygen your cells would die.  The reason being oxygen is crucial to cellular respiration.  The classic metaphor is to compare cell respiration to a burning trash fire.  If you throw a blanket over the burning pile of trash you smother it (block the oxygen) and the fire goes out.  Without red bloods to carry oxygen to the cells the cellular fires would go out.   If you want to know more about cellular respiration, the Krebs Cycle, ATP and all that good stuff I suggest you start with the reference given below.  Meanwhile keep on asking questions.

Oxygen is only the supporter of combustion.\nYou said that a burning matchstick when brought close to oxygen burns brightly only.\nThe matchstick is burning due to red phosphorus only.when its brought nearer to oxygen its burning brightly.\nThe gas needs LP(liquified petroleum) to burn.We need not to add oxygen because oxygen is present in large quantities.

To understand that, you have to understand more about crucifixtion.  The nails are through the hands and feet.  In order to breathe, the person being crucified has to push up against the nail in their feet. That hurts, but can still take a while for them to die. When breaking the legs, it just speeds up the process because then they have to push up against the broken legs as well to breathe.

oxygen is needed to convert glucose into energy.Without oxygen the body cant make energy without making lactic acid as well. Thats why you get stitches when you run out of breath. Didnt you pay attention in biology?

Yup, oxygen oxidises our bodies. As we are carbon based lifeform, we lose carbon when we breathe out - hence, carbon dioxide.

Aluminium is a chemical element and metal.\nAluminium nails would be nails made of this elements.\n\nCorrosion/rust is the contact of metals with oxygen (another chemical element and part of the air around us), the process is alled oxidation.\n\nThe best example is the metal iron reacting with oxygen from the air  and the result would be rust. (it works better with water as ths contains more of the element oxygen). The surface becomes reddish-brown and briddle, more oxygen can penetrate the metal and in the end the piece of metal breaks, "it rustes away".\n\nAlumumium does react withs oxygen but only on the surfcae, in common language you could say its "rusts". The surface than looks greyish.  But in comparison to iron this forms a protecting layer on the surface of the aluminum, no oxygen can get deeper and the aluminium stays stable.\n\nThat is one of the reason airplanes are made of a very pure aluminium. They should not rust.

The tip I give to my student is to always FINISH with the element that has only one type of atom, like O2 or H2.  This way, when you balance it, you won't disturb any work done previously.

You know all the dangers? You sure? Acetone peroxide, known as "Mother of Satan" is extremely heat, friction, and shock sensitive, causing a huge explosion. In other words, heat, friction, and even a sharp motion could cause it to explode. If you have to ask Yahoo Answers how to dispose of acetone peroxide, you really shouldn't be near it. At all.\n\nEDIT: But if you really want to know, it is polar.

There are two things to consider:\n\n  In a blood transfusion, they don't always give you all the components of blood (the red blood cells, the platelets, the plasma, etc.).  In a normal transfusion, the person ONLY gets red blood cells and the plasma.  Neither of these has DNA...  Red blood cells do not have have a nucleus at all; that is why your body is constantly making new ones (and why you can keep giving blood without eventually "running out").  The plasma is just "fluid", so there's no nucleus there, either.  So, just getting a normal transfusion will not expose you to DNA.\n  Second, IF DNA somehow got in, I don't think there would be enough of it to cause any problem.  It would only be a small amount (because blood is largely plasma and cells) and, so, any DNA would not be common and, thus, probably easily handled by your body's defense system.  \n  Besides, DNA would only be a problem if it was in a cell where it can be translated and transcribed into gene products (proteins, etc.).  If it was just "floating around" in your blood, product wouldn't be made from it.  Also, the DNA would probably degrade fairly quickly.  DNA is sturdy, but blood has plenty of enzymes and different pHs that would most likely damage the DNA in some way.\n  So, that's my answer.  the second part was a little bit speculation, but I believe I'm right (I KNOW I'm right about the first part).

H2O2 or Hydrogen Peroxide is a corrosive and oxidizer and reacts with all types of metals (except stainless steel and aluminum), dirt, leather, ect. If you would like to see how 70% concentration reacts with a leather glove or laundry detergent. send me an E-Mail to m00nd0ct0r@yahoo.com and I'll send you the two videos later tonight when I get home form work.\n\nP.S. I'm working at a Hydrogen Peroxide plant right now.
