N₂O₄ (g) ⇌ 2 NO₂ (g)
Kc = [ NO₂ ]² / [ N₂O₄ ]
4.2 = [ 0.785 ] [ N₂O₄ ]
[ N₂O₄ ] = 4.2 / 0.785
[N₂O₄ ] = 5.350 M
hope this helps!

The answer is hydrobromic acid.
That is the name for aqueous HBr is hydrobromic acid.
If there is no water that is if it is not aqueous then the name will be hydrogen bromide but as it is acid and in aqueous state so the name will be hydrobromic acid. As it is acid that's why the suffic ic is used and as it is in aqueous state, so hydro is used.
