the car fuel from what mixture does it consist?
970712
typical gasoline consists of hydrocarbons with between 5 and 12 carbon atoms per molecule

A pure substance would be 100% one type of atom/element, such as gold (Au).  A mixture, is a combination of two or more types of atoms/elements.

The fuel used in Formula 1 is now very similar to the one we put in the tanks of our family cars. This was made possible by strict regulations on fuel imposed by the FIA.\nFor example, Ferrari uses fuel that is very similar to the one that people use to fill their cars from Shell gas stations. Williams has fuel probably similar to the one in the Petrobras network, and Renault probably uses similar fuel to Elf gas stations.

It's difficult to answer this question.  Everything has a freezing point, also called the melting point because it is the transition from solid to liquid or vice versa.  The reason it is difficult to answer this question is because gasoline is not comprised of one molecule.  It is a mixture of hydrocarbon chains, between 5-10 carbons long.  If you did it correctly, you could freeze gasoline and that would separate the mixture.

It is mostly composed of alcohol.  An alcohol/gasoline mix has a lower freezing point than straight gasoline, and mixing in alcohol does not adversely affect the combustion characteristics of gas in most engines.

Lets start with the pure substance.  It is all the same element or compound.  Solid, liquid or gas, the entire sample is exactly the same no matter where we look at it.  It is considered homogeneous.\n\nTwo or more pure substances when mixed to become homogeneous are called a solution.  Solutions can contain solids, liquids or gases but must be homogeneous (the same in all areas).  Most important solutions contain one or more solids dissolved in a liquid.  The solids are called solutes and the liquid is called the solvent.  When the solutes are mixed with the solvent, the homogeneous solution is formed.\n\nA mechanical mixture is a mix of substances where the final sample is not homogeneous.  Sand is a good example.  Even if fused into sandstone, some areas are different than other areas.  These are called heterogeneous.  Smoke floating in air is heterogeneous.  It is also a mixture.\n\nImpress your teacher with this example of a sample which contains only one element, but is still a mixture.  Diamond dust mixed with graphite dust.  Both diamond and graphite are made of pure carbon, yet the mixture is heterogeneous so it is a mechanical mixture.

Traditional gasoline formulations (i.e., those that do not contain ethanol) are almost completely immiscible in water, and vice versa.  That is, water has very limited solubility in gasoline, and gasoline has very limited solubility in water.  (The addition of ethanol to gasoline significantly increases the solubility of water in the gasoline, though.)\n\nAssuming "traditional" gasoline, and assuming zero mutual solubility, we can easily solve your problem.  \n\nWater has a density of ~ 1 gram/cm^3, so 50 grams of water occupies 50 cm^3.  Gasoline has a density of 0.73 gm/cm^3, so 50 gms of gasoline occupies 50/0.73 = 68.5 cm^3.  The total volume of the system is therefore 50+68.5 = 118.5 cm^3.  The total system has a mass of 100 grams so the average density is 100 grams/118.5 cm^3 = 0.844 gm/cm^3.\n\n[Note added after several people have responded with incorrect answers.\n\nThe answerers who have simply averaged the densities of gasoline and water are incorrect.  If the problem asked for the density of a mixture of equal *volumes* of gas and water, then you could simply average the densities of the individual fluids.  This is not what is being asked, though.  The question asks for the density of a mixture of equal *masses* of gas and water.  Equal masses of gasoline and water do not occupy equal volumes (obviously, because they don't have the same densities).  TO solve the problem, one must first find the volumes occupied by 50 grams of each fluid, then divide 100 grams (the total mass of the system) by sum of the two volumes.]

Most fuel (other than hydrogen, nuclear etc) is hydrocarbon.\n\nPlastics, solvents, most paint, most (all?) man made clothes, the insution on the wire...\n\nA bit of "building block" for modern material as well as fuels, solvents and some medicines too!!!!

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.

A mixture is a physical combination of two or more pure substances in relative amounts. It is called an impure substance when it contains a substance that is much greater than the amount of other substances in a mixture. \n\nHope this helps,\nUltimeaciax

of course gas but if cant get that any flex fuel additive sold at auto stores. (or can order by gallon for you) with common ratio of 1 pint additive to 5-10 gals coco or other subsitute. theyll know which is best. also if use gas youd want 1 gal per10 gals of your substitute fuel.

Hi,, hydrogen, oxygen, and nitrogen... \n\n good luck.....

85% Ethanol; OK, stay with me now.........\n\n15% of a gallon = gasoline.  1 gallon = 4 quarts\n\n15% of 4 quarts = .6 quarts = 1 pint, 6 tablespoons, 1 teaspoon\n\nSo, you would need to mix 1 pint, 6 tablespoons and 1 teaspoon of gasoline with every 3.4 quarts of ethanol

They use methanol.  Probably about 100 gallons or so per car.

mixture, usually if you can see the individual "ingredients" its a mixture.

Gasoline is made up of hundreds of components.  Too long to list.\n\nIn short, here are the names of just a few compounds in gasoline:\n\nBenzene\nToluene\nXylene\nethylbenzene\n1-methylbenzene\nn-propylbenzene\n1-methyl-3-ethylbenzene\n1-methyl-4-ethylbenzene\n1,3,5-trimethylbenzene\n1,2,3-trimethylbenzene\nnaphtalene\npentamethylbenzene\nC10, C11, C12 benzenes\nmethanol\nbutane\nnaptha\nethanol\nisopropanol\nt-butanol\nn-propanol\nMTBE\nsec-butanol\nDIPE\nisobutanol\nETBE\nt-amyl-alcohol\nn-butanol\nTAME\n\nThose are just a few components in gasoline.  \n\nNow, if you want the complete list, go buy yourself a $55,000 gas cromatograph, set it up for gasoline component detection and have a blast.

Well, you picked a dandy of a problem, seeing as gasoline isn't one particular chemical structure (for example, it isn't like C5H8 or anything). So, during combustion, you have the hydrocarbon part of gasoline combusting, but you also have some other hydrocarbon parts combusting, as well as other additives combusting and changing due to heat.\n\nMy advice? Change your topic.
