The reaction is:
Cu + 4 HNO3 = Cu(NO3)2 + 2 NO2 + 2 H2O
This is considered an acid/base reaction.
The reaction of a protein (with aromatic rings) with nitric acid produce the yellow xanthoproteic acid.
The composition of hno3 is HNO3 , with one hydrogen atom, one nitrogen atom, and three oxygen atoms. The name of this molecule is nitric acid. Refer to the related link for a structural formula of nitric acid.
Nitric Acid is a fairly strong acid. The loose H-N bond is why it is an acid to begin with: the oxygens pull electron density away from the Nitrogen and weaken the bond between the nitrogen and hydrogen, allowing it to easily fall off. Nitric acid is also the only compound to dissolve metallic copper!
15M nitric acid (HNO3) is a concentrated acid. In a reaction between iron and concentrated nitric acid, iron (III) nitrate [Fe(NO3)3], nitrogen dioxide (NO2), and water (H2O) are produced. The balanced reaction is as follows: Fe + 6HNO3 --> Fe(NO3)3 + 3NO2 + 3H2O

Reduction-Oxidization (Redox) reaction
oxidation
The reaction of copper pennies (pre 1983) is a very intense exothermic reaction. The copper is oxidized by the acid.
Copper(II) Oxide: CuO reaction with Nitric Acid: CuO + 2 HNO3 => Cu(NO3)2 + H2O Copper(I) Oxide: Cu2O reaction with Ntric Acid: Cu2O + 2HNO3 => CuNO3 + H2O
Copper+Nitric Acid - Copper Nitrate
Yes. Dissolution of a copper penny would indeed be a chemical reaction.
reacts, forming nitrogen dioxide gas, can be a violent reaction
in study island, the answer is "The reaction between the copper and the nitric acid produces heat. It is exothermic."

Pieces of copper are added to hot concentrated solutions of hydrochloric, phosphoric, sulfuric and nitric acids. A reaction clearly takes place between copper and nitric acid. The presence of copper ions can be observed by adding each solution to a dilute solution of ammonia. If copper ions were present, we would see the blue color of the copper-ammonia complex. Sulfuric acid has oxidized the copper metal, as indicated by the blue color. Nitric acid is a stronger oxidizing agent (and produces a higher concentration of copper(II) ions), as indicated by the darker blue color.
Copper dissolves in any oxidising acid like nitric acid.
