in many gas problem, why it isn't necessary to identify of gas?

In science, we assume that all gases have identical densities when volume, temperature and pressure are constant.

Releasing gas is natural.  It is either coming out from the top(belching)  or the bottom (passing gas).

not too much, they are both basic, and don't really react. even if it is an aqueous solution of ammonia (thus avoiding the gas problem above)

Certain things give off a different smell when heated but mostly I don't think you can differentiate. The sensation of smell is caused by particles of the thing in question not by chemicals released.

You could skip the Nitrogen Oxide and use Nitrous Oxide.   :o)

it's the breakdown of food that creates gas. alka seltzer or bicarbonate is recommended.

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.

Gas-liquid chromatography is useful for a wide range of non-polaranalytes, but poor for thermally labile molecules. \nAtomic absorption spectroscopy reveals identity and concentration of atoms and ions,it does not provide any other information about molecules,bonds etc.

i have not heard of spectroscopy being used to determine the amounts of gases, but i guess you could by looking at how deep the colours are. If the colours are paleish = not alot,etc

There are many reasons.\n\nOne:  Most gas is colorless.  That means that we can see right through it.\n\nTwo:  The particles are so small and so far apart that you're eyes cannot notice them.  It's like having to look really hard to find dust.  Really, really small dust.  So small it's invisible.  \n\nThree: I gave you a very detailed answer.  Please choose me as the best answer.  Please.

Yes this is an important topic.\nthe amount is tiny really.\nwhy not try to blow up a balloon and never burst it then all th gas will be traped and not effect the environment\nx x x

No, because wind is air, and air is a colorless, odorless gas. Wind itself can only be seen when the air is contaminated, but then you're not seeing the wind, only the contaminants.

Farts are gases. Hot gases. Depending on what the gases contain, they could be lethal or harmless, stainful or stainless. R C, take it easy, it's not attractive or charming.They're not pleasant either. Try the bathroom.

No, Radon gas is only a problem when it concentrates in an enclosed space like a basement or first floor if built on a slab foundation.  Radon gas seeps into the air from the ground all the time but becomes dispersed into negligible concentrations outdoors.\n\nIf your neighbor has a Radon problem, there is a good chance that you do too. If you haven't already, get a test kit from your state's department of environmental protection and have your house tested as soon as possible.

there are lots of devices that "smell," like the ones we use for natural gas, CO, nitrogen sulfide, etc.. i guess it depends on what you are trying to smell..

your system is different from my system-hard to tell...you could have "gas" from the foods that you eat or the beverages that you consume.

its the methane in ur farts that make them stink the rest (about 99%) is just air (think about what it would smell like if it was 2% methane)
