Yes. Dissolution of a copper penny would indeed be a chemical reaction.
It is a chemical change because new chemical compound are formed. For example Copper plus Nitric acid would produce Copper Nitrate and Hydrogen gas.

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
The reaction of copper pennies (pre 1983) is a very intense exothermic reaction. The copper is oxidized by the acid.
Any reaction between nitric acid and ammonium nitrate.
chemical equation involved in the reaction between concentrated nitric acid and galactose
Copper+Nitric Acid - Copper Nitrate
reacts, forming nitrogen dioxide gas, can be a violent reaction
