chemistry assistance please!?

Well, you may know you can synthesize CuSO4 with sodium hydrogen sulfate and copper metal if you heat it in a test tube over a burner, but, i have one question, is it possible to do the same with zinc in the place of copper in an effort to produce zinc sulfate? i want this simply as i want some glow powder,but, is this method possible? If not, tell me a simple way. (if there is one...)

Two chemistry related questions.?

I have three chemistry questions. 1) What is my result when I mix baking powder(NOT sodium bicarbonate)and vinegar? 2) What is the result when one burns steel wool? Is Iron Oxide my end result? 3) When mixing vinegar and baking soda if I were to keep the mixture under pressure would the water and co2 stay as carbonic acid or still decompose into h2o and co2?

how can i make sodium hypochlorite bleach from rudimentary material.

Please help me to make sodium hypochlorite bleach from rudimentary material for sterilisation purposes ( i was told by a US trained man that it was so) someone told me to check you out on the net.(that u knew all sorts of wonderful hands-on chemistry) and for mouth wash. it is for a rural health post in northern ghana. we buy the stuff from accra and transporting it across the country to the north is making the cost difficult for the rural folks here to afford. but they need it as cheap as possible for hygiene purposes.

Can anyone help me identify some chemistry glassware? Answered

I recently acquired some old glassware from a university sale, and I have a couple of pieces that I have not seen before.

The second looks like an addition funnel with a water cooled stem.

How can I purify mineral oil?

My early experiments with oil-cooling my PC lead to some chemical *discoveries* The first was mineral oil will dissolve latex rubber.  I was using surgical tubing to pump the oil to the radiator and after a day the tubes had softened and swollen so much they wouldn't stay attached to the pump.  That and the oil turned an ugly yellow. (* the second was warm oil reacts with PVC, and causes the insulation on usb cables to become brittle) I'm working on the next gen of the project and I'd like to clean up the oil, but I can't quite google my way to a solution. I have filtered the oil (removed all the bugs) though a coffee filter, and a couple of paint filters, I don't have any reason to believe the rubber is suspended and filterable, but I could be wrong. Any chemists out there know what I can do?

Anyone savvy with Air Electrodes??? Thanks! =)

I'm posting this after having googled, of course...I work with DIY fuel cells using off the wall fuels. By far, the most expensive component of my FCs is the Air Electrode which I purchase from Electric Fuel Ltd. in Israel. The material was invented in 2008 (as far as I know) and EF were the ones who bought the patent (according to the inventor himself...sorry but his name eludes me). Anyhow, I was wondering if anyone knows how to make good air electrodes. Something that would give me at least a vold in reference to the SHE (V=0) and a current density of up to a few hundred mA/aq cm...The stuff is basically this, from the electrolyte side to the air side: Separator paper, Carbon powder with Manganese or Cobalt catalyst mixed in (and a binder of some sort, I suppose), a Nickel mesh (current collector) and a bit more Carbon+catalyst then a microporous Teflon(r) sheet (permeable to gases but not to liquids). I cant find nickel mesh where I live but the other stuff I could get--the Teflon(r) being replaceable with oil paper??? Any help would be greatly appreciated. N.B: I am Not trying to infringe on a patent, just trying to make some "homebrew" air electrodes for R&D; since I am still (steam comes out of ears) self-funded and low on Thanks a lot!!! =)

Butane distillation

I have instructions for extracting pure esential oil from plant material using butane. The problem I have with it is that at the end, the butane is vented. I just don't feel right about venting unburned hydrocarbons into the atmosphere. I've been looking at glass lab equipment (distillation tubes, connectors, etc). I have no background in chemistry, but it seems to me it shouldn't be too difficult to put something together using standard glass lab equipment to capture, distill and reuse the butane. Butane boils at 31 degrees farinhite and is heavier than air. At the end of the process, the oil is scraped from the bottom of a drying dish. Does anyone have any suggestions on how to put something like this together? Thanks

How can I make a biodegradable adhesive in a paintball-like form-factor that's durable but would break if thrown.

Scenario: you're riding your bike. A car cuts you off. You have a little hopper full of these balls and have the presence of mind to get one out and throw it at the car. It sticks to the car. When the driver gets home, he sees it. Inside of the clear adhesive is a laminated piece of paper or something durable with a link written on it. The driver goes to the website and reads instructions about how to be a better bike-friendly driver. They wash the adhesive off with no damage done to the car. They become more conscientious drivers.

in distilation , how is a condenser set up? Answered

after watching a video made by nurdrage and realising i could use a condenser to distill various chemicals like ammonia water, i was wondering, how is a condenser set up. now ive looked at a lot of images, and all i see is the top of the condenser where the gas enters, thenthe bottom where the gas exits as a liquid. now what i dont nderstand is the two middle middle nozzles, ive looked at many setups and theres usually nothing attached to them, or they have a hose attached to them that goes nowhere and you cant see where they end, so i must ask, what are they for, in the sense, what do they do? and what, if anything, are they attached to? whoever answers my question properly and makes sense will receive a best answer. also, i will just add, ive searched through google and wikipedia, and found zilch that made any sense to me.

I have used bleach to make rust(with salt), how can I seperate the rust from the salt? Answered

I was looking for a way to make rust (ironoxide) and found that bleach coul be used as an oxidizer; however, I would not know when it was finished breaking down. With some research I found that NaClO + H2O2 -> O2 + NaCl + H2O. I think I can use this to either: use the NaClO and make the ironoxide, then add the H202 to break do the residual NaClO (extra H2O2 can be evaporated with the H2O), or used the reaction to speed up the ironoxide making with a bit of extra H2O2 to insure all the NaClO is used and the evaporate off the rest. (which would be better? would be my first question, but not the most pressing one) My question is how can I sepperate the Iron oxide from the NaCl (salt), since both are water soluble (sp)? A filter will seperate out larger pieces of ironoxide, but there will still be a fair amount that passes through the filter with the salt and I would like to minimize my loses as much as possible.

Bonding hydrogen and oxygen to make water? Answered

Ok, so I got how to get water, but how do I condense it without losing much, and would it be at least a semi-efficient and/or fast way of obtaining around a cup of water? So, I have another question. I know, I've been posting a new question at least once a week for a while now and you're all probably like "Dark Master87, Y u no shut up and stop trying to do impossible things?? w(O;O)w" Most people on here probably know about electrolysis and seperating water into hydrogen and oxygen with electricity, but it's simple and I don't currently have a use for it. But does anyone know how to bond hydrogen and oxygen to create water? I'm expecting there to be heating or cooling involved, probably more likely heating. Would you light the two gases on fire? Or would they just automatically bond with each other at the point of contact? More importantly, would this be possible to acheive on the limited budget of a 14 year old hobbyist who *may* have access to *some* lab equipment, but probably not? Thanks for paying attention, if it's not feasible/possible, I won't mind if you nag about me never doing any reasonable projects. And also, how hard would it be to get the hydrogen and oxygen from electrolysis with losing too much of it?
