Will the electrolysis of potassium ferrocyanate or potassium ferrocyanide yield any dangerous gases??

yes, you'll get hydrogen cyanide. you could perform the experiment in a gas chamber, but its quite dangerous

The answers are KCl, CaF2, and Na2O. Potassium has one electron on the outer ring while chlorine has seven. To make chlorine's ring "full" potassium gives the one electron to chlorine. They are "happy" now. :) That's what my science teacher told me. He's weird.

Since there are no metallic ions like sodium or copper to produce intense visible light wavelength emissions, I would suspect that the flame would be colorless or the kind of yellow flame you see at natural gas flaring.  I've not done this experiment (it's pretty hazardous).

Yes, it actually is that simple. Potassium bonds very well to both chloride and bicarbonate. Potassium has a +1 charge, while both chloride and bicarbonate have a -1 charge.\n\nCheck out this site for a detailed description of these three electrolytes and their effect on the body:\n\nhttp://www.medicinenet.com/electrolytes/article.htm

take a 9 volt or higher battery,attach a wire to the pos terminal and 1 to the negative terminal...stick wires in water dont let em touch...after a while youll see bubbles on each wire....Hydrogen will be the bubbles on 1 wire and oxygen on the other...this is splitting the water molcules..

it is a chemical reaction and the gas is c02

Heating the soda will easily drive the CO2 from solution.  \nCO2 is not naturally very soluble in water because it is nonpolar, while water is polar, and for gases, heating decreases solubility enough to allow nearly all of it to come out from solution.

You must be talking about Potassium Chloride solution and not Potassium Chloride in molten form. So it would contain K+, Cl-, H+, OH- ions, and once electricity is passed through, K+ and H+ migrate to the cathode. Hydrogen being lower in the electrochemical series get discharged first as Hydrogen gas, (2H+ + 2e- ----> H2) and both Cl- and OH- ions migrate to anode but because of concentration effect, Cl- loses electrons and get discharged as Cl2 gas. (2Cl- - 2e- ---> Cl2) Thus K+ and OH- ions are left behind. These form Potassium Hydroxide and all group I hydroxides are alkali hence the resulting solution is alkaline.

You are not likely to be exposed to large enough amounts of cyanide in the environment to cause adverse health effects. The severity of the harmful effects following cyanide exposure depends in part on the form of cyanide, such as hydrogen cyanide gas or cyanide salts. Exposure to high levels of cyanide for a short time harms the brain and heart and can even cause coma and death. Workers who inhaled low levels of hydrogen cyanide over a period of years had breathing difficulties, chest pain, vomiting, blood changes, headaches, and enlargement of the thyroid gland.\nthe answer to you question depends an the amount, did the person die from cyanide? tobacco smoke is the most common source of cyanide exposure for the general population. So no, your lungs aren't going to anyone, but other parts might. But if it's hydrogen cyanide or cyanide salts these produce spores, and no one is going to want anything from someone with these kinds of spores

Nada. Absolutely nothing will happen. your strongest oxidizing agent is water and strongest reducing agent is Zinc. These guys cannot have a spontanious reaction. If you pass some electricity though it (more than .07V) then you'll end up w/ some zinc hydroxide. If this reaction happens in the presense of oxigen then also some zinc hydroxide can be formed. other than that nothing.

Gas-X and Listerine!?!

B, though its even more common as K2Cr2O7\n\nby coincidence, C, Na and H2 happen to be quite good reducing agents.

your kidding right, in water??  All you would end up with is very strong bleach if you use chlorine.  Both are used in keeping pools (which are full of water) from having molds and other harmful substances.  Ignite, don't make me laugh.  \n\nThe line of elements that react violently with water is Sodium, Potassium, Rubidium, Cesium, and Francium.  Each reaction is stronger as you head down the periodic table.

Sure.  Any element can be purified.\n\nNitrogen is fairly easy.  All you have to do is liquify air and let the oxygen and other gases boil off at higher temperatures.  Just reduce the liquid down to around 75 degrees Kelvin.  Water vapor, CO2, and Nitrogen oxides will form solids, which you can decant the liquid from.  Then raise the temperature to about 78 degrees and the nitrogen will boil off (at 77.K, -196C), leaving oxygen which boils at 13 degrees higher.  Collect the gas, nitrogen, that boils off.  If you need to make it even purer, repeat the separation process with the "pure" nitrogen.

Cyanide and acrylic acid.
