Oxidizing agents are reduced during a reaction, meaning they gain electrons.\n\nNitric acid is an extremely powerful oxidizing agent.\n\nOxalic acid, mentioned in a previous answer, is actually a very common reducing agent.

A) an oxidation reaction\n\nthat's why they are called redox

Oxidising chemicals (of industrial strength) should not be stored next to oxidisable materials. These generally would be flammables such as organic solvents.\n\nCorrosive chemicals are not necessarily oxidisable.

Vitamins that are antioxidants include:\n\nVitamin C\nVitamin E\nBeta Carotene (a form of Vitamin A).\n\nA couple of antioxidants that are frequently mentioned but are not vitamins are Green tea and Selenium (a mineral). \n\nA good way to ingest the necessary antioxidants is by both eating a sufficient amount of fresh fruits and vegetables that are loaded with many of the mentioned vitamin antioxidants and also take a multi vitamin supplement.\n\nIf you need any clarification, please contact me through "Answer" and I will change my response accordingly.

I would say CH2O2 (I'm assuming you mean formic acid, not dioxirane), CH3CO2H, and water.  \n\n"Important" is a tough word here, as all of these compounds can participate in h-bonding to varying degreees, with water being the strongest and CH2F2 being the weakest.  That said, strong hydrogen bonding gives rise to many of the nifty properties of water and in all three cases the h-bonding is powerful enough to raise the boiling points to be significantly higher than what you would expect based on molecular weight.

Oxygen aton as such called as "Nascent Oxygen". It is highly reactive and powerful oxidising agent.\n\nO2 is oxygen "molecule"... the roperties of this will be different than "Nascent" Oxygen!\nGood luck with u r school project!

Well Im not sure what youre exactly looking for but the basics of it is oxidation passes the electron and reduction accepts the electron.  There are some basic rules for assigning oxidation number and its best to memorize them for a test or something

Many materials can react with ozone to form oxygen as a by-product.  Most all are reducing agents.  A more definitive answer rests on how you are using the term "element".  If you are using it the periodic table sense then your answer would include many of the metals capable of being oxidized.

They react with oxidant molecules and free radicals that are present inside your body. Highly oxidant molecules otherwise react with proteins and cellular components, that can damage cells.\n\nSo antioxidants help to protect your cells.

Anything that has do with antioxidents. \n\n\nHerbs vary can in effect depending on the soil. There are no standardizations tracking these types of variations.

I am making assumptions here, I am presuming that you are talking about biology and are speaking of Reactive oxygen species and the formation of free radicals within the body.\nI hope I am correct. \nReactive oxygen species or ROS are species such as superoxide, hydrogen peroxide, and hydroxyl radical and are associated with cell damage.\n\nFree radicals are also produced inside (and also released towards the cytosol) organelles, such as the mitochondrion. Mitochondria convert energy for the cell into a usable form, adenosine triphosphate (ATP). The process in which ATP is produced, called oxidative phosphorylation, inovolves the transport of protons (Hydrogen ions) across the inner mitochondrial membrane by means of the electron transport chain. In the electron transport chain, electrons are passed through a series of proteins via oxidation-reduction reactions, with each acceptor protein along the chain having a greater reduciton ppotential than the last. The last destination for an electron along this chain is an oxygen molecule. Normally the oxygen is reduced to produce water; however, in about 1-2% of all cases, the oxygen is instead reduced to give the suproxide radical,·O2-. Superoxide needs an additional electron to make it more stable, so it steals an electron from the nearest source, such as: mitochondrial DNA the mitochondrial membrane (called lipid peroxidation), or from protein, or from reductants such as Vitamins C or E, or, from non enzymatic antioxidants such as glutathione or thioredoxin. If too much damage is caused to the mitochondrion, it goes through apoptosis, or programmed cell death.\n\nBcl-2 proteins are layered on the surface of the mitochondria, detect damage, and activate a class of proteins called Bax, which punch holes in the mitochondrial membrane, causing cytochrome C to leak out. This cytochrome C binds to Apaf-1, or apoptotic protease activating factor-1, which is free-floating in the cell’s cytoplasm. Using energy from the ATPs in the mitochondrion, the Apaf-1 and cytochrome C bind together to form apoptosomes. The apoptosomes binds to and activates caspase-9, another free-floating protein. The caspase-9 then cleaves the proteins of the mitochondrial membrane, causing it to break down and start a chain reaction of protein denaturation and eventually phagocytosis of the cell.\n\nAccording to the Free Radical Theory of Aging, aging occurs (via a loss of energy producing cells) either when mitochondria begin to die out because of free radical damage or, when less functional mitochondria remain within these cells. The focus of the project is to neutralize the effect of these free radicals with antioxidants. Antioxidants neutralize free radicals by donating one of their own electrons. The antioxidant nutrients themselves don’t become free radicals by donating an electron because they are stable in either form.\n\nSuperoxide dismutase (SOD) is present in two places naturally in the cell. SOD that is present in the mitochondria contains manganese (MnSod). This SOD is transcribed in the nucleus and has a mitochondrial targeting sequence, thereby localizing it to the miotchondrial matrix. SOD that is present in the cytoplasm of the cell contains copper and zinc (CuZnSod). The genes that control the formation of SOD are located on chromosomes 21, 6, and 4. When superoxide dismutase comes in contact with superoxide, it reacts with it and forms hydrogen peroxide. The stoichiometry of this reaction is that for each 2 superoxide radicals encountered by SOD, 1 H2O2 is formed. This hydrogen peroxide is dangerous in the cell because it can easily transform into a hydroxyl radical (via reaction with Fe2+:Fenton chemistry), one of the most destructive free radicals. Catalase, which is concentrated in peroxisomes located next to mitochondria but formed in the rough endoplasmic reticulum and located everywhere in the cell, reacts with the hydrogen peroxide and forms water and oxygen.

Vitamin E, one of the antioxidants, can be taken regularly as part of a daily vitamin and mineral supplement or spread as in an ointment on sunburn. Vitamin C is another antioxidant that will help prevent severe damage from sunburn and shorten its effects. Selenium is a mineral that will help fight sunburn.
