Why Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) reaction really occurs?
Copper is attacked by molecular $\ce{HNO3}$, and neither by $\ce{H+}$ nor by $\ce{NO_3^-}$ ions. The equation is : $$\ce{3 Cu + 8 HNO3 -> 2 NO + 4 H2O + 3 Cu(NO3)2}$$ At high $\ce{HNO3}$ ...

Why Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) reaction really occurs?
It is true that Copper has a negative oxidation potential hence H+ ion is unable to oxidise $\ce{Cu(s)}$ to $\ce{Cu+}$ or $\ce{Cu}^{2+}$.
It is the reason why Copper does not react with strong mineral ...

The edge case of an edge case: Vapor emissions of the descaling agent Sulfamic acid
According to the Handbook of Chemistry and Physics, sulfamic acid $\ce{NH2SO3H}$ is decomposed at about $200°$C in $\ce{NH3}$ and $\ce{SO3}$, which produces immediately ammonium bisulfate $\ce{NH4HSO4}...
