Great homework question. Except, no one but you has the necessary info to answer it.

its a disinfectant - kills bacteria (germs)\n\ncheck the label though...

The simplest way is spectography. if you are speaking of a breathalizer test it is via conductivity.

The water isn't involved in the reaction, so take it out.  Then, just put a 2 in front of the Nh2(SO3)H and a 2 in front of HNO3, and you're finished.\n\nNow, go take a nap or go to sleep...

H2SO4 will dehydrate and remove water.\n\n\n(CH3)2 CH - CH2-CH=CH-(CH3)2

OH-(aq) + HC2H3O2(aq)---> H2O(l) + C2H3O2-(aq)

Well use a series of steps.\n\n1st step add Calcium Carbonate. This will fizz in the case of the vinegar, as acid plus carbonate gives salt, water and carbon dioxide. U can even test the gas to be CO2, as it turns lime water milky. U will eliminate the vinegar from further tests.\n\n2nd is separate the alcohol from the salt and fresh water. Do this by testing with Cobalt chloride paper. The paper changes from blue to pink if any water is present. The sample which doesn't change the paper would be the alcohol.\n\n3rd is to separate the salt water from the fresh water. Do this by adding silver nitrate followed by aqueous ammonia. Salt contains sodium chloride, so the presence of the Cl- ion will cause the formation of a white precipitate that dissolves in excess alkali.\nSo, the one that produces no ppt is therefore pure water.

by electrolisis\nH2O------>H2+O2\ni.e by passing electric current

the only way I can see this, is to disolve ozone (O3) into water. Ozone is already used to disenfect chirgical tools

figure out the efgfect of the enzyme. Or you can test DNA structure. Inhibitary enzymes have a blacked actionsite whereas activation enzymes have activation sites open to substrates

I suggest hydrogen peroxide 'bleach' because it is much less toxic than regular bleach, but it still destroys many pathogens.\n \n Also, 70% Isopropyl alcohol is a good disinfectant.

These are the right ones:\n\n2K(s) + 2H2O(l) ---> 2KOH(aq) + H2(g)\nH2SO4(aq) + 2KOH(aq) ---> K2SO4(aq) + 2H2O(l)\nCa(OH)2(aq) + 2HCl(aq) ---> CaCl2(aq) + 2H2O(l)

You can either look it up or determine it experimentally.\nI cant get much more specific without additional details.

Test for sulphate\nIt is best to perform the wet test\nNow add salt:sodium carbonate in the ratio 1:3 in a beaker and dilute it with 20cc of water. Next heat it for 10-20 minutes, and then let it cool, now filter the extract. The extraxt(filtrate) is called Soda Extract or Sodium Carbonate Extract\n\n1) For sulphate\nAcidify some extract with HCl acid and add Barium Chloride\nWhite colour means sulphate\n2) for Cl\nAcidify extract with nitric acid and add silver nitrate, white means chlorine

The easiest way to find out the answer to that question is to look up the MSDS.  It gives all the information you need about it's toxicity, reactivity, etc.  A lot of chemical supply companies have MSDS on their websites, and I think there might be a government website that has MSDS accessible online, but I'm not sure.

Usually by adding copper, transferring the sample into a special reactor which makes it possible to capture resultant gas, and adding acid in order to move the cyanide from a large volume of sample to a small volume of analyte. Depending on your lab, you can determine the cleansed analyte by gravimetry, photometry or titration.\n\nNeedless to say that the process of driving out the cyanide needs to be placed in a suction board and supervized...
