What are oxidizers and fuels?
611975
Fuels are substances that burn by combining with oxygen.\n\nOxidizers are substances that generate oxygen when they take part in a chemical reaction with the fuel.\n\nSince oxygen is provided by the oxidizing agent, the reaction can take place without air. This is what happens in explosives.

Because is just a fake: chemically speaking it is impossible to oxidize water in a combustion engine in order to win energy. Water already is the product of an oxidation. Would be similar, if somebody invent a stove which is run on ash instead of wood.

The main products still are carbon dioxide and water, together with carbon monoxide and various substances collectively referred to as soot. Soot basically is the attempt to form graphitic carbon in the flame finished before a sufficient quantity has formed to create crystals. Substances in soot usually are polycyclical aromatic compounds, or heterocyclical compounds like furanes.\n\nIn the case of impure fuels, additional side products can be found. Presence of halogens leads to formation of dioxines and similar compounds. Presence of sulfur leads to all kind of noxious substances. Etc.\n\nIncomplete combustion doesn't provide well-defined reactions.

Sludge formation is prevented.\nExisting sludge is broken into minute particles and burnt.\nClogging of fuel lines and filters is prevented.\nAtomization of fuel is improved.\nDeposits on burner nozzles are eliminated.\nFlame is stable, hotter and in the required direction.\nCombustion is catalytically improved.\nSoot formation is reduced.\nFireside deposits are eliminated.\nHeat transfer is improved.\nVanadium and sodium in the fuel are neutrallized.\nFormation of sulphur trioxide is prevented and corrosion is inhibited.\nStack temperature is reduced.\nCarbon monoxide, oxygen and unburnt hydrocarbons in the stack gases are minimized while carbon dioxide in stack gases is increased.\nFrequent cleaning, maintenance and overhaul are not required.\nFuel consumption is reduced by 4-6%.

These answers are all correct yet incomplete.\n\nFor complete combustion of a hydrocarbon (the major components of gasoline are hydrocarbons), the products are water and carbon dioxide.\n\nHowever, combustion in the everyday use of gasoline is not necessarily complete, and the products due to incomplete combustion of a hydrocarbon are water and carbon monoxide.\n\nAlso, in theory, the combustion occurs when oxygen and hydrocarbon are chemcally reacted with each other.  However, in practice, the oxygen supply comes from air, which is predominantly nitrogen, and the heat of combustion will contribute to the combustion of the nitrogen.  The products of combustion of nitrogen are NO2 and NO3, commonly known as NOx.\n\nThe main fact left out in the previous answers, are that gasoline is not solely composed of hydrocarbons.  In addition to the fuel additives, which are predominantly formed from carbon, hydrogen, and oxygen, there are also sulfur-containing organic compounds that are considered impurities (ie, could not be removed during the refining process).  The products of the combustion of these sulfur-containing compounds are carbon dioxide, carbon monoxide, water, and SO2 and SO3, commonly called SOx.\n\nCombustion of gasoline will also have particulate matter as a byproduct. Is is similar to smoke you see when burning any fuel.  Incomplete or inefficient combustion can lead to small amounts of carbon not being oxidized, leaving carbon dust, or coke, as a product.  This dust can also be a carrier for other pollutants or by-products and depending upon particle size, can be very harmful to human respiratory health.\n\nFinally, since some of the fuel may not be completely combusted, volatile organic compounds, or VOCs, will be products as well.

Well the obvious one about explosions and fires.\n\nThen you have that some of the propellants used can be pretty nasty to handle.  Liquid Oxygen, Liquid Hydrogen, etc are very cold and if you spill on yourself you won't live very long.  Liquid Oxygen (along with pretty much any other oxidizer) will allow things to burn very well.\n\nThe hypergolics are the really nasty ones though.  They tend to be toxic and if you mix them they burn (which is why they're called hypergolic and is an advantage in many cases) and some of them are known carcinogens.

Petroleum fuels are made of Hydrocarbons (molecules made up out of Hydrogen and Carbon).  When you combust/burn a Hydrocarbon in excess Oxygen you produce Carbon Dioxide and Water (incomplete combustion also produces Carbon Monoxide).\n\nTake gasoline for instance, mostly Octane (C8H18), the reaction shown below is the complete cobustion reaction which occurs,\n2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O\nThe fuel is chemically changed into Carbon Dioxide (which is not considered a fuel) and Water.  If we assume complete combustion, there is no fuel left over.\n\nIf you were to split up the Carbon Dioxide (or in your case CO that is produced through incomplete combustion), you will obtain elemental Carbon and Oxygen gas.  Carbon could be considered a fuel since it could then undergo further combustion with Oxygen however, it is not a Hydrocarbon fuel since it has no Hydrogen (all the Hydrogen went into water).

Hydrogen. You can create it from water using only electricity so it's the cheapest fuel ever. When you explode it (during combustion), it mixes with oxygen to create...you guessed it...water (no polution).\n\nSo:\n1.Free\n2.No polutants\n\nHmmm...

Fire is the act of oxidizing fuel.  The hydrogen and oxygen are already bonded, so there's not fuel or oxygen.  Steam is just a state change, not a chemical reaction.

The air we breathe is 78% nitrogen, 21% oxygen and a small amount of trace gases.  Under normal conditions, the air provides the oxygen which allows other fuels to burn.\nHowever, under pressure and very high temperatures (such as in a automoblie engine), the nitrogen can chemically combine (burn) with the oxygen gas to form a series of compounds called nitrogen oxides.  Some of these are serious air pollutants.\nSee the site below for additional information:

Fuel, Heat, Oxygen - Also known as the traditional fire triangle.\n\nFuel - Something that can be burned\n\nHeat - The fuel must be heated to the point that it can burn.  Yes, it's true that once the fire starts it can and does generate it's own heat, but if that heat were removed somehow (i.e. the application of water), the fire goes out.\n\nOxygen - Fire's need oxygen to burn.  This is either the oxygen in the air, or from the chemicals that are burning, such as oxidizers.  If you were to interrupt the oxygen with say another gas, such as CO2 (as in a CO2 fire extinguisher), or blanket the fuel with dry chemical, a fire blanket, foam, etc., the fire goes out.\n\nThere is actually a fourth component to fire, and that's the chemical chain reaction itself.  Adding this forth component changes the fire triangle to a fire tetrahedron.  If the chemical reaction is halted, say by adding Halon, FM-200, FE-13, or some other gaseous fire extinguishing agent, the fire goes out. (and NO, halon does not "suck" all the oxygen out of the air, there's much more to it than that.)\n\nThat all being said, I like hatingmsn's answer that you may also need a permit!  HEHE... good one and may actually be a fifth component!

combustion of a fuel involes it reacting with air to give carbon dioxide and water...its not the by-pdts which makes the fuel good but the energy liberated in the form of heat and light,which is then used to do work

Can't answer this one accurately with the limited information you gave. What is being burned? Under what conditions is it being burned?  When you're talking of by products as opposed to products, the composition of the combustible material enters the equation. If you are burning a pure hydrocarbon fuel such as methane the products  are water vapor and carbon dioxide. Depending upon the conditions under which it was burned you might also get carbon monoxide. If the combustible material contained sulfur, nitrogen or other elements you might get gases such as sulfur dioxide or nitrous oxide as well.
