Question

The Statue of Liberty is made out of copper and was once shiny and copper -colored. Over the years the copper has gone through a process called oxidation. where it has changed into a new material. What has occurred? an endor Termic reaction an energy formation a chemical reaction a precipitate formation

Answer 1

The process that has occurred is a **chemical reaction**. When the copper on the Statue of Liberty oxidizes, it reacts with oxygen in the air and other environmental factors, such as moisture and pollutants, to form a green patina primarily composed of copper carbonate. This change in color and composition indicates a chemical reaction has taken place.
