this is just a thought if you were to make nitrocellulose could you reuse the 50/50 sulphuric acid/nitric acid mix after you all ready nitrated some .5g cellulose to make some more nitrocellulose

how would i distill potatos to make vodka? would i just put them in the distilling flask with some ethynol or something? We are using the distillation stuff in chemistry, and the teacher said bring anything in to distill Anyone know anything exciting to distill

Hello, I have a question, in a book i read that CH4 + O2 = CO2 + H20. Now I notice that there are 3 oxygen oxygen in the reactants and only three are there in the products. From where did that extra molecule come? I also notice that there are 4 hydrogen atoms in the reactans and only two in the products...did those hydrogen atoms "rearrange" themseleves to form oxygen molecules??? What did happen??? Encrypted

Has anyone heard of cyalic acid? what is it used for? How can you get pure manganese from manganese dioxide? thanx

Hello, I was wondering what sort of acid would be sufficient for going through, let's say, a pine table when you pour like a deciliter on the table? That's an experiment I've always wanted to do, but it seems that a heavily diluted solution of hydrochloric acid just isn't enough. I wonder if concentrated sulfuric acid is enough? Or perhaps nitric acid?

I have heard of making dextrin but cant really figure out what it's for. I assume it's a binding agent in black powder, but does it affect the explosive properties of your BP or is it just to make it a "solid"? Also does it become solid like a rocket engine or like playdough?

how does one name esters of organic acids that have multiple acidic functional groups (ex citric acid)? what would it be called with say, 1 of those groups "esterfied"? what about two? what about all three?

Not too long ago I had the oppurtunity to work with ferrocene in the lab. I proceeded to carry out an acetylation reaction on the compound. What did astound me was the stability of ferrocene, a pale orange powder at room temperature.......can anyone explain why it is so stable ? The reason why I ask is that looking at its molecular structure it seemed to me to be unstable in nature. And if it is indeed so stable how come no one could synthesize it before the mid 20th century. One organo-metallic I have extensicesly studied is the Grignard reagent, unfortunately I never acctualy had a chance to deal with the chemical, can anyone please comment on its stability and phys…

A bit of an unusual question for you all, I am sure, but a rather easy one I'd say. I recently purchased a used book from a library and would like to remove the writing on the inside cover that has the library's name. What would be the best way to go about doing this? I have considered using bleach but am afraid that it will either eat through the cover or not do the job. Thanks in advance.

Just reading this months chemistry world. Apparently some guys from Belgium (K Huvaere et al., Photochem. Photobiol. Sci., 2004 (DOI: 10.1039/b403666b) if you're interested) have found that a set of chemicals found in beer called isohumulones, which are important for beer foam stabilisation decompose under UV to 3-methylbut-2-ene-1-thiol which is a bit stinky and doesn't taste nice. Kind of explains why a drink so fast when it's sunny!

I am putting double gas tanks on a friends truck and i cant find the valve i need. they make the one i need for Liquid Propane and i was wondering if i could use that valve without any problems. your help is greatly needed

I need a little explaination on how to measure the relative quantities of Vit C in different citrus fruits (mandarin,Orange,kiwifruit,lemon) What is the method of how this is done? by simple school labs of course Can somebody please outline the procedures i use to do this?

One day, I heard some sulphur dioxide on some fruit from newspaper. It said that sulphur dioxide react with water to form sulphuric acid. Is SO2 + H2O ----> H2SO4 SO2 + H2O ----> H2SO4 + O2 true? However, they seem that they doesn't make sense. They can't be balanced. Therefore, I guess 2SO2 + 2H2O + O2 ----> 2H2SO4 right?

Is it true that 1 zip of "etilenglycol" can kill you?

Take a look at a simple addition polymerisation reaction: http://dragonslair.europe.webmatrixhosting.net/Science/Chemistry/Hydrocarbons/polymer.htm Its from my website itself. See the formula that can be used to show the polymers in a row. Now, I have two questions about this: a) Bonds are formed during polymerisation, so, is the reaction exothermic? b)What about the atoms that lie at the end of the chain? What about their side bonds that is supposed to link to other atoms? What happens to them? I don't want an answer like "There are millions, so these are ignored", however, I want to know the facts!

Hi, Im trying to find out if you can retrieve paraformaldehyde from formaldehyde solution by evaporating off the water? or will the HCHO just evaporate away with it? Thanks!

Me and a some friends were curious as to what "substance" causes the discoloring of the teeth in coffee. We were also wondering if this "stain agent" could be taken out or if it is possible to make a clear or "non staining" coffee. Sorry if this is a stupid idea, its just that so many people spend lots of money getting their teeth bleached, and if there is a way to prevent the staining in the first place..Then.. Well you know the rest. Thanks, any input would be appreciated

The displayed formula if polystyrene looks very similar to a poly ethene molecule. The only difference is that it has a ring of 6 carbons. Here is the quiestion: Are the carbons connected by double bonds? If not, then where is the 4th bond, as each carbon will only have 3 bonds connected to it

Hey, can anyone confirm with me that the formula of citric acid is C6H8O7-? or is iit C6H8O7-3? Thanks.

I've taken a decent amount of organic chemistry courses as an undergraduate, and the one question that was never touched on is, why does carbon form so many compounds? Does anyone have a good answer to this?

ever notice how at land fills a great amount of CH4 is burned all the time? that's such a waste. CH4 can't undergo condensation polymerization since it's the same compound and can't donate an OH. CH4 can't undergo addition polymerization because it isn't an alkene or alkyne. still, shouldn't there be a way to do something like; CH4(n)->C8H18(n/8)+H2(n/2) of course, it would be difficult controling how much polymerization occurs, but still, couldn't the CH4 be used to produce useful fuels?

for a moment ignoring anything living that produced it, what else or how else is methane gas formed? for example, some planetary bodies or their satellites, have methane(gas), methane(liquid), ethane, etc. or does simply an abundance of (or contact of) Carbon and Hydrogen atoms and it form anywhere, anytime?

I'm doing an experiment where i make acetaminophen from p-aminophenol. I then make phenacetin from acetaminophen and in the final stage i synthesise dulcin. The problem i have is i can't figure out the reaction mechanism of the last step and i've looked all over. See the picture for the reaction. Can anyone explain to me how the NH2 group is built in and replaces the CH3 group. Thanx

I visited aommaster's website science section. under organic chemistry, he put the word alkynes.. he had no explaination for it too.. So my question is, What is Alkynes? Has it got any relation to do with Alkanes and Alkenes?

Our research group is to develop materials and techniques to reduce environmental pollution. However, it can be often seen toxic chemicals release in our lab. For example, some toxic reagents release into water and some harmful organic gases release into air. I am just confused. Could anyone introduce the situation of your lab?
