Respuesta :

copper oxidizes in moist air
2Cu + CO₂ + O₂ + H₂O = (CuOH)₂CO₃

copper reacts with concentrated acids, for example, with nitric acid
Cu + 4HNO₃ = Cu(NO₃)₂ + 2NO₂ + 2H₂O

copper reacts with chlorine
Cu + Cl₂ = CuCl₂

copper reacts with oxygen when heated
2Cu + O₂ = 2CuO

The chemical reaction has been defined as the reaction in which the change in the chemical composition of the substance takes place.

The copper has been the element of group 11, and has been a highly reactive metal.
