ithink your talking about E85, the 85% ethanol and 15% gasoline. there are about 600 pumps nationwide right now, but you can look up more information here http://www.e85fuel.com/index.php

That is virtually impossible to answer, as gasoline is a mixture of different hydrocarbons varying from 5 to 10 carbon atoms per molecule.

No, water (H2O) and Gasoline [mostly Octane] (C8H18) are quite different on a molecular level,\nFor one, water has no carbon, and Octane has no Oxygen.

Since propane has three carbon atoms the isomers could be\n\nCl(CH2)-CH2-CH3\nor\nCH3-CH(Cl)-CH3\nThe isomerism in it is structural or position isomerism.\n\n\nThe reaction is as under\n             SN2  \nC3H9 + Cl2 --------------> monochloropropane\n\nThe mechanism is Nucleophilic Substitution. It is usually SN1 that is Unimolecular substitution.

If your compound has the formula C6H10, then the molecular weight would be 82 grams/mole\n\nYou could have one of 13 different compounds -- \n2,3-dimethyl-1,3-butadiene\n3-3-dimethylbutyne\nCyclohexene\nany one of the five hexadienes\nany one of three hexynes\n4-methyl-1-pentyne\n4-methyl-2-pentyne\n\nWhat is the rest of the question regarding the 5.3*10^-23 odr?

20) B.  CH4\n24) C.  nonpolar with difference between 0 and 1.7\n25) B. pentane (more carbons to branch)\n27) C. H and Br\n28) C. 5 pairs - 3 between carbons and one on each end between carbon and hydrogen\n29) B. nylon

I don't know that question.\n\nI can tell you that it's an octahedral complex. The two isomers would be CIS (Both chlorides adjacent to each other) and TRANS (both chlorines opposite each other)

There are a few isomers possible.\n\nEssentially there are two C's double-bonded, with either 2H's off one C and 2Br's off the other C.\nOr 1H and 1Br off each C

The octane number just means the percent octane that the gas is.  A higher octane number burns better, but is more expensive.  The normal (cheapest) gas is 87 octane, which means it is 87% octane and 13% heptane.\nFuel addatives either increase fuel economy or the life of the engine.  They help the fuel burn better
