FAQ

Laser and inkjet coated paper coated paper what is different

If you use color ink-jet printing effect is certainly not a good laser.

Sucrose- check for conductivity x for solubilty

I won't give you the answer to each question, and I'm not quite sure I understand the question. But a good rule of thumb is that ionic compounds (metal + nonmetal) are always conductive and covalent compounds (nonmetal + nonmetal) never are. As for solubility, polar dissolves polar, so for example sodium chloride (NaCl) is both conductive and soluble.

Yeah, well I was thinking of running a current through water to produce hydrogen gas, harvest it, and try out a little explosion.So.what material should I use for the electrodes? Does it matter? I don‘t have any real electrodes, but I do have paper clips, pencil graphite, iron rods and copper. I do have stainless steel, but this would produce chromium I am pretty sure, and that is dangerous.Basically? Do electrodes only have the effect of changing electrolysis rates? or also their products?

Electrodes are likely to corrode, depending on what you dissolve in the water to make it more conductive. A metal as the negative electrode won't corrode because of the electrochemistry there, but the positive electrode attracts the negative ions and discharges them, so Cl- becomes chlorine gas, very corrosive. Or OH- becomes oxygen, likewise. So use graphite as it won't oxidise at temperatures with water around. Pencil graphite is not very conductive: disassemble a spent battery cell and use its carbon electrode. Copper sheets at the positive terminal can develop very colourful oxidations: quite pretty. This is called anodisation. Try bubbling the hydrogen and oxygen into the same container, such as a one gallon plastic container. Discharge FROM A DISTANCE with a spark plug or a fuse wire. Do not use a match! Do not mess about where static electricity might strike a spark.

Out of what materials can I make a spark gap? I am trying to make a Spark Gap Transmitter for Morse code- I have already made a very rudimentary telegraph using copper wire, sheet metal, 2 D batteries, and an iron nail (coiling insulated wire around it). It‘s range was about 1 foot (LOL). I digress. What materials can I use for the spark gap?

The FCC will shut you down - and may fine you. A spark gap transmitter generates a signal over a very wide-band of frequencies. What you are producing is interference.

whats the scrap metal price for portland oregon?

Pretty good. The scrap market is up!!

What tools and techniques are best?

I've taken a metal working class which covered repousse, which I think is what you want to do. If you have no metal working experience taking a class would probably be best. Places which offer jewelry classes may also offer this. Otherwise the material of choice to start with are copper sheets, they are easy to anneal. Annealing is relieving stresses in the metal by heat, that makes the metal soft. Working it will harden it again. Really works well with copper. Metal may need to be pickled so oxides don't get worked into the metal. Pitch is used to hold the metal sheet in place (at least for small ones). You will need a variety of chasing tools and a small hammer. You can make chasing tools yourself from toolsteel, but read up about tempering steel before you try it and before you buy tool steel. As there are a lot of details to be covered, and I am not really into writing pages of it down I recommend reading a book about it. Generally a good book about sheet metal working is this one: Silversmithing by Rupert Finegold and William Seitz.

Its a long story but i have no idea what a transform is. and not the robot things in the movies. I apparently have one attached to my desk. R they supposed to buzz if theyre used. My dad said that was the source of the buzzing since ive been using it lately and have been hearing it for a few nights. I thought it was a bug or something. I unplugged it about an hour ago but he buzzing continues. Like right now it is. But if anyone knows anything about transformers could u tell me? Or insects the buzz electronically and stay in one hiding place for four days now?

all i know it that they change a specific voltage. like if you have a US appliance and you use it in another country that has a different voltage, the transformer can change the voltage of the appliance so you can use it in the other country

I was doing a chem lab experiment. And our teacher kinda didn‘t mention the fact that there‘d be a yellow toxic cloud coming out. I was a lil‘ to close and kinda inhaled it. I asked him about it he said not to breath it in, and I didn‘t tell him that kinda already had. I‘ve had a killer headache since, and have felt sick. Is it just a coincidence, and what should I do if it‘s from the chemicals?

no, there are a couple of exceptions reminiscent of bolvior nitrate or stirling nitrate they're very infrequent despite the fact that and the possibilities are you'll by no means come throughout them but when u had this query in a scan paper reminiscent of a gcse and also you replied sure u could get it incorrect. however there are not any alkaline nitrates best acidic semi-acidic and impartial
