The first one has not yet understood very well the risks for his lungs... ;D

Seriously, the first one has a concentration > 98% and so it absorbs water vapour, fuming in air.

Quote
While the pure acid tends to give off white fumes when exposed to air, acid with dissolved nitrogen dioxide gives off reddish-brown vapours, leading to the common name "red fuming acid" or "fuming nitric acid". Fuming nitric acid is also referred to as 16-molar nitric acid as the most concentrated form of nitric acid at Standard Temperature and Pressure (STP).

(P.S. Looking up in wikipedia it's a too difficult task, isnt'it?  ;))

Like, how it reacts with oxide and metal...

Why should it react any differently unless it has other different compounds in it (the fuming one that is)?

I think depending upon dilution and also Ph value excertion..

It depends the law  "equal = equal "

I am also still in the research name called --- "Cyclic oragnic proton repulsion"
I am trying to help people with my research and also for nobel

Cyclic organic proton repulsion eh? Sounds very fancy. :)
What is it?

Like, how it reacts with oxide and metal...
fuming acid:     HNO3 + X --> Y

non-fuming acid: HNO3 + X --> Y

X = metal or oxide.

The difference in reactivity is apparent in other kinds of reactions, as nitrations of organic compounds.

What I meant is that fuming or not-fuming nitric acid is ~ the same, for what concerns reactivity with metals or oxides and that a difference can be in others kinds of reactions, but I prefer not to talk about explosives here...
