Chemistry

Here I want to ask you a couple of questions.Thanks 1. What happens when ferrous hydroxide is heated strongly? My idea is that it would turn to ferrous oxide at once and later oxidizes by oxygen in air. And what's the colour of unhydrous ferrous oxide and hydroxide? 2.Does hypochlorite react with acidified potassium permanganate? Thanks for attention

Hi there, im new here, so be nice Anyway, I have this image which i would love someone to have a look at, as I need to find an answer but so far I am stumped, I've spent a long time looking around on the net and in various books. Thanks very much, oh and sorry if I put this thread in the wrong forum. What I need to know is the chemical structure? Noel

I was wondering just how deadly Cl2 is. Is it on the order of Insta-Death? Or more like being trapped in a room full of it for a couple of minutes will make you woozy?

I got a big chunk of it from science class... it tasted friggen horible, we were studying minerals and i took some. so anything cool i can do with it... besides tricking my brother into eating it:cool:

I was browsing woelen’s page and I saw the page on green fire: http://woelen.scheikunde.net/science/chem/exps/borate_ester/index.html having some boric acid and some denatured ethanol around I gave it a try. After burning about 40ml in the dark (you have to see it for yourself, I mean green fire, awesome!), I turned on the lights and found the bathroom filled with a light ‘fog’, I noticed some sort of vapor coming off of the flames earlier too. Could this just be a light smoke? I used Ace Denatured Alcohol, which says it contains “Methanol, Ketones, Ethanol”. Any ideas on what this fog is?

Does anyone out there know how I could make my own scintillation cocktail? I am planning on making a display of different home-made types of radiation detectors.

ok - so I openly admit I know practically nothing about chemistry. I'm writing a book for children at the moment aimed at the 8-12 age range. As part of my plot I need a chemistry experiment which a 12 year old would be able to do. I would like it to push the limits and maybe be slightly dangerous; perhaps include a noisy, visual or smelly reaction. It's set in school and the chemistry teacher is nasty so I need it to be something contraversial - perhaps not widely used in school. It must use some sort of open jar that can be lidded after the experiment, and it needs to ideally involve the use of a solid. Is there some sort of simple experiment where you put somethin…

ive been looking on the internet for a way to make copper (ii) hydroxide. it would really help if u guys could give me a way to make it using other substances. i would also need an equation like EX. H + O ----> HO

Everybody take a look at this! http://www.unitednuclear.com/legalaction.htm If what it says is true, then this could mean the end of chemistry experiments for a lot of people at this forum! This cannot happen! Let me hear your opinions.

Hello I've got my chemistry coursework under exam conditions tommorow and I've got to say what the hazards of the unknown acid/alkali in the titration may be... Could you give some general dangers/hazards of acids/alkalis...thanks. I'm much grateful:-)

Hi everyone! As some of you may be aware Wikipedia is currently running a set of projects in all of its areas one being a chemistry project. The goals of the project are things like improve quality and depth of articles in the chemistry field (Also sub-divisions for things like Drugs, compounds, polymers etc.). We have a lot of knowledgeable people here who know information about compounds and chemistry as a whole so here is an idea how about we have a project here to develop chemistry articles and then add them to Wikipedia and develop existing articles? It would be an interesting project and hopefully would provide good quality articles because right now…

i heard it has oxygen in it or sumthing... what ways can i get either pure oxygen from it or pure hydrogen from it? i tried electrolosys with watter to get oxygen and hydrogen but its way to slow...

i read this on a website "A regulated DC voltage source is preferable to ordinary batteries. Use a supply with built-in current limiting- this is a feature of almost any decent power supply, but double-check just to be safe. You can start the source out at its lowest voltage setting and gradually increase the voltage until a steady, controlled electrolysis reaction is taking place. Electrolysis can force many chemical reactions to go against their "normal" (spontaneous) direction; this will occur when a certain electric potential (i.e., applied voltage) is reached. For example, an electric current can cause Pb++ ions in water to form PbO2 (solid) and H+ (aq.), a react…

Hi all, Is it possible to have more then 3 bonds, I have heard of 1, 2, and 3 but I have never heard of a bond number greater then that… does anyone know if its possible and have any resource links for more information? (Maybe explain a little about them too if possible). Cheers, Ryan Jones

How can i purify it? right now i only have 3% and thats not good enough so how can i purify it? oh and i dont have any non household items i can add to it so pleese dont suggest it. Thanks for the help, dcstegg

Dear All, a useful source of interesting chemicals are found "locked" up within the plastics we consume each day. Is there a simple and clean method of extracting say terepthalic acid and other derivatives from these?

HI , Kind of new to this forum. We know Elements make the Compounds and in some cases we have strange structures which make Solids. Can someone please explain to me the precise Structure in Metals? How can an electron have freedom(delocalized) and yet hold on to the mettallic structure by behaving like a localized entity? Thanks.

The electron configuration of V is [Ar] 3d3 4s2 and Cr is [Ar] 3d5 4s1, the electron in 4s subshell is transfered to 3d subshell for extra stability, stability by the half-filled 3d subshell. And Ir is [Xe] 4f14 5d7 6s2 while Pt is [Xe] 4f14 5d9 6s1. Mt first question is why Pt's configuration is like that but not [Xe] 4f14 5d8 6s2, how can the electron in 6s subshell be transfered to 5d subshell, in case of 5d subshell is either half-filled nor fully filled? And one more question, where does the stability of Au and Pt come from?

Doesn't have to be one thing, can be a mixture. Even something that is impractical on account of it's cost or weight.

I've searched all over the place, and i can't find it. So does anyone know what the flame temperature of isopropyl (rubbing) alcohol is? P.S. Doesn't matter if it's 70%, 99%, or 100%

Hello. I have a question about Alu insertion... Is it possible to predict out of 13 people, how many people will have Alu insertion gene and how many won't using Hardy-Weinberg equilibrium? (or how many will have +/+ , +/-, -/- ?). I have a lab due in about a week and I don't understand what HW equilibrium is... thx:-)

hey guys and guls, i was just wondering if you can show me how to work this question out? consider the following reaction: H2S(g) + 2 NaOH(aq) -> Na2S(aq) + 2 H2O(l) How many grams of Na2S are formed if 2.05 g of H2s is bubbled into a solution containing 1.84 g of NaOH, assuming the limiting reagent is completely consumed? Be great if you can help, im having problems working out these questions. Hayz

How does hydrogen peroxide (~ 30%) act as an oxidising agent (Co2+ --> Co3+), while at the same time a producing a gas (I assume it's oxygen)? This all happens in acidic solution. I can see how it works if it's in alkaline solution. Thanks for any help.

Well i found a little extraction method for myself that ive never exactly heard of: lets say you take a solution of something in water, then u add 200 proof EtOH, and some of the stuff that was in the water precipetates out n u can collect. Just thought i would share this, guess its a form of crystallization.

One day this week I made some tea and put sugar in it. However, it was really hot and I was in a hurry so I put it in the freezer to cool it off a little. Well, I forgot about my tea and found a tea popsicle in my freezer, complete with a spoon handle. Well, it tasted pretty good, except that the top (part closest to the handle of the spoon) was really sweet. I was wondering what happened to the solution as it cooled. Did the sugar all rise to the top and start to crystalize as the solution cooled? Also, when I managed to get it out of the mug it almost immediately began dripping. It was sort of like the tea was draining from from the ice. So I'm just curius a…
