yeah, its outdoors... and i just remembered i forgot they had to be put in right proportions
and thanks, i got the idea of substituting with NH4NO3 from you on another post
ah sorry didn't see the latex equations at first, so from what i see, this is the basic idea...
a small amount of ammonium nitrate turns into nitric acid, which oxidizes copper (your first/third equation)
the NO2 released partially helps reformulate the nitrous and nitric acid (your fourth/fifth equation)
nitric and nitrous acid react with HCl to give N2, Cl2 and NOCl (and NOCl > 2NO + Cl2) (your sixth/seventh/eighth equation)
the chlorine also oxidizes copper... (your ninth/tenth equation)
here's a picture... you can definately see and smell a little chlorine
sometimes i can see little brown traces of what looks like NO2, but i can't say for sure
actually copper was not the best metal to choose for this experiment, since nitric acid by itself can eat through copper.
even vinegar + H2O2 can dissolve copper
