naptha is it the same as naphthalene?
141767
No, no and no!\n\nNaptha is a very light petroleum product, some examples would include camping fuels and rubber cement solvent.\n\nNapthalene  is a crystalline, aromatic, white, solid hydrocarbon, best known as the primary ingredient of mothballs.

is it the same bottle? if not, put them is separate bottles.

1,2-Bis-(2-naphthyl)-2-hydroxy-ethanone (2-Naphthoin)\n\n.................O\n..................||\n(2-naph)-C-CHOH-(2-naph)\n\nwhere (2-naph) represents the 2-naphthyl group [C10H7-]\n\n(ignore the dots in the structure above -- they are used to hold the spaces that Yahoo otherwise deletes)\n\nTotal empirical formula would be: C12H16O2

CH4 is given to the abreviated name methene, (methanol). It is actually metholethaline. or as we like to cll it on the Hazmat squad, methandeathanol.  Very leathal in large quantities.

almost the same\n\n:> peace

I understand that the compound in question is soluble in both pet. ether and ethanol. The reason why pet. ether is preferred must be to do with the volatility of pet. ether. \n\nYou can easily evaporate pet. ether, which is why this is preferred over ethanol. \n\nThanks.

Yes, they are the same thing.  Good luck on your test.

they are exactly the same - just slightly different terminology \n\nepinephrine is the "americanisation" of britsh adrenaline

Well they both have six carbon atoms!\nBenzene has an octane number of 101\nn-Haxane has an octane number of 25\nso i guess the answer is false

&#92;\n..&#92;\n..-----&#92;\n........&#92;\n.........&#92;\n(ignore the periods)\nx axis: time\nY axis: temperature\nThe step is there because the nature of cooling objects. As the naphthalene is cooled, its temp first decreases normally. However, when it begins to solidify, the heat being removed is used up as naphthalene molecules are subjected to intermolecular forces and begin to become a solid. Therefore, the horzontal part is where the substance becomes a solid. Finally, when the naphthalene is fully a solid, the temperature decreases again. An easy way to picture this concept is with boiling water. As some water molecules change to the gaseous state, the temperature of the water does not rise above its boiling point. This is equivilent to the horzontal part of the naphthalene cooling curve. As the substance changes states, energy is being generated/used up, and the temperature does not change for a time. When the conversiion is fully made, the temperature continus on its original course.

Some of the basic ingredients are the same.

Your unknown compound might be an impure substance.  The impurities will skew the melting point.  You should find out if the substance is pure or not.  Pure substances (that is, with nothing else mixed with them) will have a narrow ranging in which they melt, for example, pure Naphthalene melts between 83-85 Celsius.

Yes. Check out this website for more information.  \n\nhttp://chemed.chem.purdue.edu/genchem/\n\nHope that helps.

Methane is a signle atom of carbon surrounded by four hydrogen atoms (CH4). Propane is a linear string of 3 carbon atoms, each surrounded by hydrogen atoms (C3H8). So no, they are not the same. Methane is also know as natural gas. Methane burns extremely clean, producing carbon dioxide and water. Propane doesn't burn as cleanly and commercialy available propane is a mixture of gases, with mercaptans added for odor detection. Gasoline vehicles cannot easily be converted to run on either. The entire fuel system, including tank, pump, lines and injectors must be replaced with new parts. It could cost anywhere between $5,000 and $8,000 (US).

Hi i've been an industrial chemist for 14 years and i'm not surprised you are confused!\nNomenclature in organic chemistry is divided into two types\nTrivial and Systematic.\nTrivial names tend to be easy to remember such as ether but are not logical. Systematic names are logical ,but, boring such as methoxy ethane (same thing)\nYou have presented two names which sound like the same molecule however the systematic names are quite different.\nHexachlorobenzene is Hexachlorobenzene\nBenzene Hexachloride is 1,2,3,4,5,6-hexachlorocyclohexane.\nIn the first molecule chlorines have replaced the hydrogens on benzene and in the second chlorines have added to the hydrogens on benzene (so it isn't benzene anymore but cyclohexane, but, the trivial name still calls it benzene to confuse you). You don't really need any tips on similar examples since in 14 years of work and 20 years of chemistry it's the only one i've ever come across!
