does sulfur dioxide dissolve in hydrogen peroxide to make sulfuric acid?

Syn-propanethial-S-oxide is the gas given off when onions are cut which makes ones eyes sting, now it says on various places on the internet that the reason why it stings is because it dissolves in the water in your eyes to give sulfuric acid, but that doesn't seem right to me since Syn-propanethial-S-oxide is C3H6OS water is H2O and sulfuric acid is H2SO4 if it is right and it does produce sulfuric acid could you give me an equation and if it is wrong could you give an equation with the correct products?

I have been searching a bit online, but I was curious to hear thoughts on ionized water. I have been considering a water ionizer, such as Kangen, for a christmas present. Merged post follows: Consecutive posts mergedFound this http://www.chem1.com/CQ/ionbunk.html

Hello everyone... I'm just angry with the ETS for asking 2 ridiculous questions in the recent GRE Chemistry exam. Imagine, they asked 'the wavefunctions of butadiene' and 'the wavefunctions of ground and excited states of the helium atom'. Hello? Do I need to memorize these wavefunctions? Just sitting for 170 minutes without food nor water is agonizing...and the exam itself is totally demoralizing...and here they are asking these ridiculous questions? My appeal: ETS examiners should test the basic knowledge of examinees in Chemistry. These types of questions are so difficult to answer given the meager amount of time. They should be more considerate to the e…

It has been known that a molecule would absorb or not absorb an energy given to it depending on the method of energy delivery. For example, a molecule may not absorb a photon with an IR-range wavelength compatible to a vibration mode which is not IR-active, hence no IR peak at that wavelength would be observed. Yet, if the method of energy delivery is not through IR but heat, that molecule would absorb the energy given in form of heat and vibrate. My confusion is, both methods confer the same energy, one in form of EM wave, another in form of heat, why the molecule absorb one but not the other? I am not sure if it is about the energy quality of the given energy form …

if calcium carbonate is heated in oxygen, will it form calcium peroxide aswell as/ instead of calcium oxide?

is hydrolysis ph dependent and give explanation if you could?

i need a chemical reaction which (if possible) would normally take place at high temperatures but, with the addition of a catalyst, takes place at room temperature (or as close to it as possible) and is easily demonstrated in a lab. any suggestions?

I'm doing a lab for my IB Chemistry class where I'm determining the affect salt content has on the boiling point of tap water. As I was writing out the procedure, I said that I was going to time how long it takes for the water to boil. My question is, given the heat and the time it takes the water to boil, is there an equation to find the boiling point? If not, is there any other way to find it?

Today I was weighing some sulfamic acid and there was some on the scale and not on the weighing paper so I blew at it. I felt a little spec of something hit my eye (I was wearing goggles, there was a little opening on the side). It may or may not have been the sulfamic acid. My eye feels fine, looks fine, I can see fine, and I didn't think anything of it in lab, but now that I'm home I just started to worry. Again, everything feels fine I just started thinking about it and I have this habit of worrying myself. I shouldn't be worried right? I'm not going to wake up blind tomorrow?

Hi everybody, I hope this is the place I can find my answer! I work for a carpet cleaning company and one of our cleaning processes for removing coffee stains involves using a mixture of 3 chemicals.. IPA Hydrogen Peroxide Ammonia My problem lies with the ammonia. Previously we have purchased something called "aromatic ammonia" or "odourless ammonia". I tried to purchase some more recently and it seems nobody has ever heard of it, let alone sells it! We had bought it from a chemical company in Southampton and it seems they are no longer trading. So I got a 1 litre sample of some "Ammonia 880-890" 33% approx and the odour is so strong it absolutely bl…

I am a chemistry beginner who has got it into his head to start learning all the elements of the periodic table. I'm looking at this wikipedia version which seems pretty up to date, but I'm not sure what the standard terms for all the colored groups are. Also other versions seem to group some parts of the table slightly differently. Normally I would just start reading up on the basics, but I want to put together a standard, simple, colour coded reference table for myself before I begin. As far as I can tell from left to right, top to bottom: 1. Pale Green Hydrogen (nonmetals?) 2. Red Alkali metals 3. Wheat Alkaline earth metals 4. Pink Transition…

So I'm looking a my school schedule for next semester and have been toying with the idea of becoming a chemical engineer, but I really don't know very much about it. So I'm thinking that I'll take intro to chemistry but the only way it'll fit into my schedule is taking it online. I'm kind of worried that it's a class that really should be taken in a class room. Should I wait, or is taking it online not going to be that bad? Thoughts.

One thing about acids that caught my attention back in high school chemistry was that they reacted chemically with metals to form hydrogen gas. Since then, I haven't done much of this in high school or college chemistry labs, but I've looked at youtube chemistry videos too, and found some things about acids and metals slightly confusing. For example, according to , aluminum is resistant to nitric acid; yet copper isn't. Hydrochloric acid, on the other hand, supposedly doesn't react with copper but does react with aluminum. Another thing is how strong bases react with metals too, such as how sodium hydroxide supposedly reacts with aluminum to form hydrogen; so hyd…

is there a way of removing carbon dioxide from sodium carbonate without having to react it with anything e.g. by heating it?

can an element which is more electronegative displace a less electronegative element in a covalent bond?

We had some fund for Halloween by unleashing three chemists to destroy pumpkins in three different ways... In the name of education of course! The three methods were smashing (with liquid nitrogen), burning with alcoholic gel and setting off a kilogram of thermite!! Video is at Any other suggested methods?

Given the temperature, pressure and density of a simple hydrocarbon, how would one go about find its identity, by using equations, and not empirical data.

Good Evening. Not having any science back ground I am looking for some assistance please. Is there a ph paper test that is able to determine the concentration levels of pottassium acetate (clearway 3 a runway de-icer) on a given area? if anyone is able to point me in the right direction I would appreciate it emmensly

I have been wondering how to calculate the angle of a bond in a chemical compound. I have found an old thread by Chemsiddiqui on the subject but no one replyed to it. As I have been learning more about covalent and ionic bonds in chemicals, I have been doodling some of my own on paper, now I am up to the bond angles and I want to create chemicals (on paper of course) that could actually exist. Thanks,

Does anybody know how to make sulphic acid out of organic compound readably available . more info A friend of mine did it and challenge me to see if i can do it. I am pretty sure it was some fluid from some insect but i have no idea.

I am making a visual display that functions with music and I am using ferrofluid, under which 30 electromagnets will be placed in a field. Has anyone experimented with ferrofluid? What power ranges for the magnets would you recommend? I don't have much time for this project so experimenting is almost impossible, but I can a little bit if I have to. I am gonna order some ferrofluid for now, and then will make more of it when I need it (I will need around 7-8 gallons, which costs way too much) I am planning the depth to be around 1 inch deep of ferrofluid. Which is probably important in figuring out the power of the magnet.

Hi, I have poster presentation on ultraviolet visible spectroscopy, But i am confused, where should i concentrate more. I have to show more on dissociation constant of drug for protein. But the information is not availbale. Note, its not acid dissociation constant but it is dissociation constant, Kd (amount of drug concentration required to saturate 50% of receptor)

what are the whole reactions and compuns made when you mix sulfuric acid with bleach/drain cleaner

how do they work
