hi all, is there any reaction similar to this:
HCl + any metal ------> H2... but with nitrogen?
Is this possible to make an inert athmosphere with this??
thanks

Nitrogen can be made by decomposition of ammonium nitrite (NOT nitrate 
).
However nitrogen isn't 100% inert, metals can form metal nitrides under heat, etc. If you want a truly inert atmosphere, try and get your hands
on an Argon cyclinder, i think it's used for welding (in an inert atmosphere, du'uh).

For more on nitrogen and inert atmosphere generation, check out this thread:
Nitrogen cyliner, welding experience required?

Chemicals.
The chemicals required for N2 production are:
• 0.20 g solid HSO3NH2 (sulfamic acid)
• 5 mL 0.5 M NaNO2(aq)
These quantities of reagents will produce approximately 60 mL of N2. The production of N2 is fast and it typically takes about 15 seconds to
fill a syringe with N2. A trace of reddish NO2 is often observed at first but soon disappears. The reaction is:
NaNO2(aq) + HSO3NH2(s) NaHSO4(aq) + H2O(l) + N2(g)
The N2 gas samples used in these experiments are generated as described in Method A. Care must be taken to stop the gas generation after the
syringe is full. This is done by removing the latex syringe cap while it is directed upwards. Rotate the syringe 180o in order to discharge the
reaction mixture and then recap the syringe.

hi, CO2 is inert? can I make an inert atmosphere with CO2??
thanks

It depends on what you’re using it for. If you want to shield steel while welding it, yes. If you want to shield something with strong bases in it,
no.

and...in distillation?

In distillation the distillate and its volitile vapors compose the inert atmosphere to many situations.
