copper oxide
Chemical change
The Statue of Liberty likely underwent a chemical change called oxidation. Before the change, the statue's copper surface was shiny and reddish-brown. After the change, the surface turned green due to the formation of a layer of copper carbonate, known as a patina, which protects the underlying copper from further corrosion.
If you use a abrasive to scrape the rust off, then it is a physical change. If you utilize a chemical that combines with the rust leaving the unoxidized penny behind, then it is a chemical change.
no because all you are doing is changing the shape and form
Production of gas: If there is a sudden release of gas, bubbling, or fizzing, it may indicate a chemical change. Formation of a precipitate: A solid substance forming in a solution can indicate a chemical change has occurred. Color change: A visible change in color of the substance can be a sign of a chemical reaction. Change in temperature: A noticeable temperature change, either an increase or decrease, can be an indicator of a chemical change taking place.
No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
i m pretty sure a colour change represents a Chemical change
Chemical change
No. Variables are things that change - the Statue of Liberty does not change height.
The statue of liberty turned green because of chemical weathering.

This is a physical change because wind and erosion are part of the physical category. Chemical change is where things happen involving actual chemicals . Wether the chemicals are from nature or not , Chemicals are chemicals. hope this helped ;] ~Lily
The color changed; a copper carbonate hydrate is formed.
walk up the Statue of Liberty to the torch with a latter and change them
false
Carving a statue out of marble is a physical change because the marble is simply being reshaped without undergoing a chemical reaction. The composition of the marble remains the same throughout the carving process.
