why would a refrigerator repair man fixing SO2 cooled friges carry a bottle of concentrated NH3?

i think it may be that SO2 will react with water to give sulphurous acid (H2SO3).  This is the common acid found in acid rain.  The concentrated ammonia may be to neutralise the acid should it be formed from the SO2 leak.\n\nPossibly anyway....

probably refers to a hydrogen attached to carbon no 4.

Older fridges used freon and it shouldn't cause you any problem.  I don't know what newer fridges use.  \n\nAlthough I do not see any problems with this... play it safe.   Fill out an incident report at work to make sure that you have this documented.  Next, have your lungs checked out.  You shouldn't have to pay for this... it should be covered by your employer.  Just make sure that you keep your company abreast of your plans so that they won't try and reject the medical bill when it comes.

I have seen them working. I believe they are the first refrigerators.  This one we had to turn down because the food was freezing in the main compartment. It seemed to work very well. The athletes bag that gets cold when you squeese it is also some ammonium salts dissolved in water.\nThe problem was I had an Uncle that passed out working on one because it uses Ammonia and water. If vented it can be poisonous.  I heard of a small box with a black panel on one side and the sun heat made the inside cool.\nThe heat turns Ammonium Hydroxide dissolved in the water into Ammonium gas and water. The mixture travels a little way outside and cools just a little. Inside the refrigerator, the tubing gets more constructed, the pressure goes up and the ammonia dissolves in the water. This is an endothermic reaction (takes heat from the environment) so it is cool. This travels more inside getting warmer and cooling the inside. Then it travels outside and into the flame again. I don't know how to engineer the amount and sizes of tubing. It does seem to work well. Perhaps for India a combination of solar and propane would work best. \nGood luck on your enterprise.

It'd be basic speaking qualitatively. NH3 is a base so any amount in water would make the solution basic.

Probably  a storage tank for alcohol in a distillary.

SO2.\n\nS202 would be Disulfur dioxide.

In refrigerator, there is a fluid gas (previously CFC). this fluid is compressed to become higly compressed gas. this gas is then passed through condenser which converts this gas into liquid. Now the pressure on working liquid is so adjusted (using capillary tubes) so that the boiling point of this liquid is lower than our desiered temperature. This liquid is then passed through evaporator (which is placed inside the refrigerator) this liquid absorbs heat from air within and evaporates which in turn passes through compressor thus completing the cycle.

Phosphine, arsine, and ammonia are all gases at ambient temperature and pressure.  But ammonia has a higher boiling point than the other 2, about -33 C.  All 3 are polar molecules.  But ammonia can form hydrogen bonds.  This increases the strength of the intermolecular forces, causing the liquid state to be more stable.

There is some 02, N2, CO2. There are also a daub of Argon, hydrogen, neon, helium, and a couple of others I don't remember.\n\nAs a matter of interest, more commercial plants that product liquid nitrogen, oxygen etc, start with liquidfied air and then separate the various components.

The name is sulfur dioxide.

You can not de-orderize NH4, believe it or not, smell is also a chemical property, although you do not want to use it to idenify chemicals.

Yes if you react NH4NO3(aq) with something SO4 you can make it.

I think you mean pneumonia...ammonia is a chemical, and a bad one at that!\n\nIt means his lungs are filling up with fluid, but not to the point or at a rate that is life threatening enough to render him ambulatory.  Meaning he can walk around while he recovers.  He'll be coughing up stuff for awhile, but eventually he'll recover...unless he stresses himself into full blown pneumonia.

It is a derivative of topuvfridge residual. What happens is a standard refrigerator takes all the thl drug elements from open food items within the fridge. This crude fermentation process is funneled out of the fridge and exhausted into the backside via a venting grill. The ions produced by the grill throw these toxins to the top of the fridge, where it forms a thin layer of dust. This dust can then be harvested and when mixed with ground up allergy pills, forms the hallucinogen "dust". Sometimes cats jump on top of a fridge and come down a raging beast. It is so powerful you have to use catnip to bring them down. This is why it is important to keep the top of the fridge clean.

Refrigerators from the late 1800s until 1929 used the toxic gases, ammonia (NH3), methyl chloride (CH3Cl), and sulfur dioxide (SO2), as refrigerants. Several fatal accidents occurred in the 1920s because of methyl chloride leakage from refrigerators. People started leaving their refrigerators in their backyards. A collaborative effort began between three American corporations, Frigidaire, General Motors and DuPont to search for a less dangerous method of refrigeration.\n\nTo some extent, CFC's have been replaced by the less damaging hydro-chloro-fluoro-carbons (HCFCs), although concerns remain regarding HCFCs also. In some applications, hydro-fluoro-carbons (HFCs) have been used to replace CFCs. HFC's, which contain no chlorine or bromine, do not contribute at all to ozone depletion although they are potent greenhouse gases. The best known of these compounds is probably HFC-134a (R-134a), which in the United States has largely replaced CFC-12 (R-12) in automobile air conditioners.\n\nIn 1928, Thomas Midgley, Jr. aided by Charles Franklin Kettering invented a "miracle compound" called Freon. Freon represents several different chlorofluorocarbons, or CFCs, which are used in commerce and industry. The CFCs are a group of aliphatic organic compounds containing the elements carbon and fluorine, and, in many cases, other halogens (especially chlorine) and hydrogen. Freons are colorless, odorless, nonflammable, noncorrosive gases or liquids.\n\nBecause Freon is non-toxic, it eliminated the danger posed by refrigerator leaks. In just a few years, compressor refrigerators using Freon would become the standard for almost all home kitchens. In 1930, Thomas Midgley held a demonstration of the physical properties of Freon for the American Chemical Society by inhaling a lung-full of the new wonder gas and breathing it out onto a candle flame, which was extinguished, thus showing the gas's non-toxicity and non-flammable properties. Only decades later did people realize that such chlorofluorocarbons endangered the ozone layer of the entire planet.\n\nSide Note: CFCs, or Freon, are now infamous for greatly adding to the depletion of the earth's ozone shield. Leaded gasoline is also a major pollutant, and Thomas Midgley secretly suffered from lead poisoning because of his invention, a fact he kept hidden from the public.
