like electrical fire, chemical fire ,house fire's.....where shd't we use water 2 put off da fire,,,what are da chemical's? in which water act's as combustion substance

Any grease fires. And you shouldnt rush to putting out a chemical fire with water unless you know what it is.

I don't know the specific name for it, but, in telecommunications, there is a certain type of plastic used for insulating wires.  This insulation is known as self extinguishing, in that, as heat is applied to it and it gets to the point where it starts to try to burn, it releases some kind of gas that extinguishes the combustion that is beginning to take place.

Definitely not water, as those three metals will burn on contact with water (and potassium will explode.) Liquid CO2 might do, as it would cool the burning material extensively, possibly below the ignition point. The sand (SiO2) would be a smothering agent. I'm not sure about the carbon tet.\n\n5 NOV 06, 1522 hrs, GMT.

If you're interested in spontaneous human combustion, it's a myth.  The human body can burn much like a candle wick will burn a candle, slowly burning away. It cannot suddenly burst into flames and burn to ash.  There have been cases that look like a body suddenly burned from within, but research has shown that there were other sources of ignition that were missed at first.  \nSpontaneous combustion is a real process in other materials though. Oily rags kept in pile in a garage, can reach temperatures capable of supporting self sustaining fire as they decompose.  Piles of old garbage with food and other material create heat as they decompose.  If they get dry enough these can cause themselves to catch fire, hence spontaneous combustion, but the human body has too much water in it to just suddenly burst into flames.

Once all the oxygen has been depleted the fire will burn itself out. Any fire must have oxygen to continue to burn. Different types of material burn at different temperatures and also determine the color of the smoke and the flame.

I sure hope this is just a paper exercise and is not going to be actually performed.  Sodium hydride will react very exothermically with water and is extremely hazardous.

Uh, your question is miscategorized\nthe metabolic process is not fire \njust because it shares a single characteristic\ninterestingly the products of hydrocarbon combustion \nare CO2 + H2O\n\nIf you get a 90% efficient furnace it will condense water in the exhaust stack

fire as in flames,in the water...

a compound has diferent properties to the elements thet make it up(usually)\n\nlike table salt, sodium- a slightly harmful reactive metal\n                 chlorine- a poisenous gas\n\nbut put them together and it flavours you food and you eat it\n\nwater stops the combustion reaction

In order: Sulfur dioxide, Hydrogen chloride (when in aqueous solutions, it is called hydrochloric acid), Chlorine, Hydrogen fluoride (when in aqueous it is hydrofluoric acid), and Hydrogen sulfide (called Hydrosulfuric acid when dissolved in water).  \n\nThey all have varying degrees of being dangerous but yes all of those are quite harmful to living things.

white. \nBuring magnesium is white hot, and believe me you wouldn't want to be near it when it does go up.  It is hot enough to break down the molecular structure of water into oxygen and hydrogen and then ignight the following gases.  Firefighters usually have to find other means to fight magnesium fires other than using water.

Are you asking about flame (as in fire), or phlegm (mucous), or what?

Fire is a process of Oxidation.  \n\nIt's temperature is equal to or greater than the Auto-Ignition Point for the fuel substance.  Each Fuel will have it's own unique Auto-Ignition Point.\n\nIt's color is determined by the elements present, and the visual spectrum of thier discharge photons...  Photons are discharge as the electrons jump from high to lower excitation levels, and each element has it's own color signature.\n\nMost fires are orange yellow and white because of the large ammount of Hydrogen in the combustion process of organic (or formerly) material.  Occasionally Red will come out thans to the carbon of the same.\n\nIf you add powered metals to the mix your flame will change color.  Copper makes a pretty green for instance...

Pretty much any material that H2O2 can't oxidize and that the water it's dissolved in can't corrode. Glass should be safe, as well as the plastic or glass container it came in. Things to avoid: "Heat, reducing agents, organic materials, dirt, alkalis, rust, and many metals. Spontaneous combustion may occur on standing in contact with readily flammable materials." (Ref.) \nThe higher concentration form (30%) is hazardous and unstable, requiring extreme care in use.

Air -- which is primarily nitrogen and oxygen with lots of other gases -- is not flammable or combustible.  It can explode from pressure (such as a ballon that is overfilled), but it cannot explode from combustion by itself.\n\nCombustion requires three things: fuel, oxygen, and heat.  It is a chemical process by which fuel combines chemically with oxygen and releases energy.  This is called oxidation.  If a fuel does not readily combine with oxygen in the presence of heat (or doesn't release a great deal of heat when it does so), it is said to be not combustible (or flammable).  The more energy a fuel releases when it combines with oxygen, the more explosive it is.  Wood burns, but it doesn't (ordinarily) explode.  But TNT explodes. So what air lacks to explode is combustible fuel.  \n\nAlso oxygen is not combustible because it is the component that combines with fuel to make combustion; we call it an oxidizer.  \n\nWhy does the sun burn?  Well in point of fact it does not combust like fire, because it is a nuclear reaction rather than a chemical one.  It's energy is in the form of radiation rather than chemical bonds.  It uses the fusion of hydrogen atoms into helium to release nuclear energy.  So while it is hot, it is not oxidizing, and so is not burning in the way that fire burns.

Fires need oxygen to burn.
