boiling point?? What is a literature boiling point?? Is it the same thing as just normal boiling point? What does this temperature tell us in regards to distillation of alcohol? (alcohol properties)

I was wondering where the addictive effect from alcohol and coffee comes from in the brain? I personally do not feel any "positive" effect what so ever from alcohol (cheer up, lose inhibitions, more talkative, ...) or coffee (stimulating). There are "consumption unrelated" things that do that...

I've tried looking for info but honestly I'm quite pissed at all the incoherence out there. Some sources say marihuana is like 3-4 times more harmful to your lungs than tobacco. However, according to wikipedia, there hasn't been a reported death directly attributed to marihuana...so how can that...

Some friends and I are working on a movie, and we need a very stringy clear slime; like is produced with polyvinyl alcohol cross-linked with disodium tetraborate. Only we need it to be food-safe, so we can't simply use that. Is there another way to cross-link PVA into a stringy slime using...

If You drink a lot of alcohol, you do not become permanently drunk. It is common for people to say that your liver does the job of getting rid of it, But How does it do it?

Me: half a bottle of 151 and a 1/4 bottle of tequila. Also 3/4 of a 5th of JD. Yes it was dumb and yes I was very sick the next day. Next?

Hello everyone! I've encountered a small problem with one of our "special" assignments. Question: The normal boiling point for ethyl alcohol is 78.4 C, S for C2H5OH(g) is 282,7 J/mol*K. At what temperature is the vapor pressure of ethyl alcohol 357 mm Hg? Maybe I'm stupid, but I can't find...

Question as stated. Just wondering because when i get cuts i put rubbing alcohol on it, but i have come to believe that that does not help the bleeding to stop.

Hey. We have an assignment where we're investigating combustion of types of 'fuels'. I chose 4 alcohols- ethanol, methanol, propanol and octanol. I did a few experiments, with one testing the heat produced Could you please explain the formula for the heat value- not quite sure what its...

I've been doing tons of research on Fick's Law. I understand how to derive it and what its used for. I just need to see an example of it being used. I need to use this equation to separate water from an alcohol and aromatic component. Any help is greatly appreciated.

Homework Statement Glycerin is poured into an open U-shaped tube until the height in both sides is 20 cm. Ethyl alcohol is then poured into one arm until the height of the alcohol column is 20 cm. The two liquids do not mix. What is the difference in height between the top surface of the...

Something I've been wondering a lot lately is how would you make your own wood alcohol? It seems somewhat simple and I can't find any decent things on google about it. Anyone know how to make? Or have a step by step process on it. Edit: Actually I think I am looking for ethyl alcohol. But both...

Homework Statement Okay this isn't really a question from the textbook or anything but I'm having a horribly hard time trying to find information on an experiment involving c14, paramecia and alcohol. There are questions I have to answer about this and I've tried googling for information for...

In humans, what exactly will happen to a young teen if he/she does weed and alcohol? Like will their growth stop such as their sex organs and their height and whatnot, or will their brain stop maturing or what? Which of the propaganda is true?

Boiling points of alcohol and mercury?? who can tell me the boiling point of alcohol and mercury??

Suppose you are given 3 alcohols primary secondary and tertiary. I have to design an experiment that can be carried out with commonly available materials and equipment that would identify the tertiary alcohol. I don't know what to do, can someone please help me out?

Explain why the aqueous washing of your alkyl halide product from the reaction of t-butyl alcohol with concentrated HCL must be carried out quickly. Washing the product with aqueous NaOH would get rid of any traces of acid left by neutralizing it, but I don't understand what time has to do...

An aluminum cylinder weighs 1.01 N. When this same cylinder is completely submerged in alcohol, the volume of the displaced alcohol is 3.88 × 10-5 m3. The apparent weight of the cylinder when completely submerged is 0.778 N. What is the specific gravity of the alcohol? m=W/g...

There's a common belief that every glass of alcohol you drink kills a certain number of brain cells. This is a myth I thought I'd clear up here, one that results from a severe condition sometimes seen in chronic alcoholics called Wernicke-Korsakov's Syndrome...

Oh now this is preposterous. I agree that in "sales" socializing in places where you can meet potential clients can result in more sales, but I don't see how Zz or Moonbear cruising bars and tying one on will increase their income. Also, you do not need to drink alcoholic beverages just...

Hi Everyone, I am pulling my hair out trying to find the answer to this question. I went to the links posted links for history, and to no avail. I've tried looking at history of egyptians, greeks etc. but their history is drinking alcohol. Does anyone have a good idea where I could start. I've...

What I have to do is find out which fuel would be best to use as an automotive fuel. My choices are methanol ethanol and propanol. My guess so far is propanol because it has a molar enthalpy of combustion of 2021kJ/mol which is close to double ethanol (1367kJ/mol) but it needs much more...

Is there an easy way to help neutralize/digest alcohol once you're intoxicated? For instance, would drinking lots of things with aceitic acid cause esterification to occur within your body, getting the alcohol out quicker? Is there something else that could be done?

when naming an alcohol, does the OH group have to have the lowest coefficient?.. just making sure...:blushing:

I try to find the synthesis of benzyl alcohol, but I can't get it. Can some one show me how to do the synthesis of benzyl alcohol, in detail. Can someone give me the website to find the synthesis of benzyl alcohol Thanks

Hi All, I have a pretty off the wall question. I’m looking for a legit biological answer, not just asking for the sake of asking. Admittedly, I like to party it up fairly often – I drink a fair amount of alcohol, but don’t do drugs of ANY kind. I’ve noticed that my senses towards sound...

Ok, I'm drinking a whisky (a rather fine Islay blend too) and I'm increasingly noticing that the feeling in my upper lip is vanishing where the drink passes over it. I can only assume that I'm directly absorbing the alcohol through my skin, and the neurones in there are blind drunk. Am I right...

I was at a science museum earlier and I saw a demonstration where methyl alcohol was put in a bottle that had two nails sticking out of the sides. Alligator clips were connected to the nails and something was connected to the clips (I think they said it was a grill starter). There was a cork...

What is it about 2 carbons, 5 hydrogens and a hydroxyl that causes people to become intoxicated when they drink alcohol? Also, why does alcohol have a degenerative effect on the liver, kidney, heart, brain etc.? Thanks, Jacob

Being a teenager and going through a Driver's Ed course, I'm constantly reminded that only time will sober you up after drinking, not a shower, not coffee, not a jog, nothing but time. This just seems stupid to me. Obviously jogging won't take you from hammered to sober, and I'm not going...

I've got some questions about the reaction of Alcohol with carboxylic acids, and the behavior of the esters formed. 1) Is there a way to determine how molar an alcoholic solution is by it's % alcohol by volume? 2) If you have determined how many moles of alcohol there are in a liquid and...

Figured this forum might be able to help more than the homework help, if not, feel free to redirect. I'm writing a program that calculates Blood Alcohol Content from various input the user gives (nothing fancy, straight forward simple calculation, prompting user for data, that sort of thing)...

Hi- For years I have always known that Methyl Alcohol is used as a method of removing water from natural gas piping. For example - a pressurized natural gas pipe has a small amount of water trapped in it. The water, under certain flow, and temperature conditions will vaporize and cause...

Lately there seems to be a lot of attention on using a Brita filter to purify hard booze in order to make it taste better. I just have to say that it works better than you can ever imagine. I ran some crappy tequila through the filter a few times, and the horrible taste is completely gone...

I have been told steam is used to turn turbines in a power plant. Why wouldn't they use ethel alcohol? It has a lower heat of vaporization. So if I am not mistaken you would produce roughly twice as much ethel vapor to turn a turbine quicker generating more energy.Any help would be appriciated.

Can anyone tell me if the revenue created from alcohol makes up for the medical bills and deaths created by it in terms of long-term revenue.

I have noticed that on days 28-4 my memory is awful. I have also noticed that during this period if I consume alcohol, I seem become intoxicated rapidly, and forget things much more than I normally would drinking the same amount. I tried to look at charts, but could not really work out a reason...

Can water or alcohol be absorbed through the skin with osmosis? More importantly can it be absorbed into the bloodstream? I know some chemicals can be, what characteristics allow those chemicals to do that? Pan
