If you are from the philippines, chances are it's methanol. It's cheap and convenient to use (in terms of burning and handling in lab classes). Just be careful. Avoid inhalation, ingestion, and skin contact. It is known to be highly toxic.

Higher specific heat capacity liquids can absorb more heat energy per unit of liquid than lower specific heat liquids.\n\nIn most applications the higher specific heat liquid will be the liquid of choice as it can "carry away" more heat per unit volume.

ch3cooh is Ethel alcohol.\n\nNa cl is salt.\n\nSalt is the better conductor, and the higher concentration of .2 moles is the better conductor.\n\nWilliam

if you look at the sequence methane ethane propane butane pentane hexane heptane ... it goes from gas to liquid, as the molecules go heavier. now ethanol is lighter than hexane, so it is no wonder that somewhere there must be a point where alkanes have a lower boiling point than ethanol. exactly where is difficult to calculate from first principles but it must be somewhere. so why not at heptane.

Water nas ethanol are totally miscibile with one another.  I do not immediately know what the mixed volume is (other than it will be less than 2 liters), but equal volumes of water and ethanol should give a 50 percent solution or 100 proof. \nThe word proof came to be used because such alcoholic liquids (100 proof and above) will burn (giving proof).

Anything that has a higher density than water.

Recystalize in methanol or water. Check the Merck index for a recrystallization solvent.

Do you mean specific (related to mass), molar or volume output?\n\nSpecific output is higher for Ethanol because it contains less oxygen in the educt.\n\nMolar output is higher for Ethanol (less oxygen, greater amount of burnable atoms per molecule).\n\nVolume output I can't do off my head, but given the greater specific output for Ethanol and assuming a greater density for it, Methanol loses again.\n\nMethanol will produce less CO2 per mol, mass or volume when burnt than ethanol, but most probably more CO2 per joule.

Physical and chemical properties\nThe hydroxyl group generally makes the alcohol molecule polar. Those groups can form hydrogen bonds to one another and to other compounds. Two opposing solubility trends in alcohols are: the tendency of the polar OH to promote solubility in water, and of the carbon chain to resist it. Thus, methanol, ethanol, and propanol are miscible in water because the hydroxyl group wins out over the short carbon chain. Butanol, with a four-carbon chain, is moderately soluble because of a balance between the two trends. Alcohols of five or more carbons (Pentanol and higher) are effectively insoluble because of the hydrocarbon chain's dominance.\n\nBecause of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. All simple alcohols are miscible in organic solvents. This hydrogen bonding means that alcohols can be used as protic solvents.\n\nThe lone pairs of electrons on the oxygen of the hydroxyl group also makes alcohols nucleophiles.\n\nAlcohols, like water, can show either acidic or basic properties at the O-H group. With a pKa of around 16-19 they are generally slightly weaker acids than water, but they are still able to react with strong bases such as sodium hydride or reactive metals such as sodium. The salts that result are called alkoxides, with the general formula RO- M+.\n\nMeanwhile the oxygen atom has lone pairs of nonbonded electrons that render it weakly basic in the presence of strong acids such as sulfuric acid. For example, with methanol:

1. No it's the methanol is a highly explosif gas.  It absorbs heat very quickly which is what makes the flame change color\n2. the whoosh sound is created by the oxygen trying to get in and the methanol trying to get out very quickly from a very small hole\n3.The jug is extremly hot because the methanol would explode if it was in contact with oxygene.  Since inside the jug, there is practicly no oxygene, it holds heat.  This is why the jug gets hot because inside it is holding heat in.\n4.  If we didnt wait for the methanol to vaporise, it would create an explosion and you would prolly die.  \n5. For a fire (explosion) to happen, you need 3 elements, heat, a burner and a burning (soryy i dunno if those are the rigth terms, i learned them in french)  The thing getting burned is always the oxygen (alone or with an organic material such as wood or paper)  Without oxygene the metanol wouldnt explode\n6.  I'm not too sure about this one, but it's probably with the moleculs.  Water is H2O and carbone dioxide is CO2.  Methanol must be a mix of those two moleculs.  Did the teahcer give you the molecular equation?\n7.  The water comes from the reaction.  You have to look at you molecular equation ( each prodoct at the beiginning and at the end)  Water is H2O  so it means that the reaction seperated moleculs from the methanol and those moleculs got paired up with some others that creat H2O. Basiclly a reaction is just moleculs getting broken and reformed with other moleculs.  Im not sure but i would guess in the methanol's moleculs, there is hydrogen (highly explosif, what creates the burning) and that hydrogen moleculs would form water with the oxygen that is burnign

one of your solvents is more polar than the other (in this case acetone) the substances to be separated by chromatography will move the most in a solvent mixture they are most similar to. Remember like dissolves like. So if your unknown is easily dissolved in a non-polar solvent like hexanes then a non polar solvent will move it the most on the paper. If your substance is very polar, IE. an organic acid. It will stay near the bottom of your chromatography paper, when using a non-polar solvent mixture. 9:1 ether:acetone is actually quite non-polar, you can progressively increase your solvent polarity by making multiple solvent mixtures with changing ratios 8:1, 5:1 etc.   Obviously, you must use a new piece of chromatography paper each time you run a new experiment (unless your spots didn't move at all!). The basic concept of these experiments is polarity and how it relates to separating a mixture. Remember, like dissolves like!

Excusme Sir, lol.. Gatorade is not the world most dense liquid.It is the one and only metal-Mercury-It has a density of i think 5g/ml
859051
water has density 1gm/ml. what ever is the volume in ml for water same is the mass in gms because density = mass/volume\n\n\ni hope it will help you out
