Question

The statue of liberty was made from copper. Which of the following is not an example of a physical property?

Answer 1

The reason that rust is considered a chemical change is because the "connections" or the bonds of atoms are changed in the process. When atoms "rearrange themselves" by changing the "connections" or bonds to allow different compounds to be formed, as is the case with the formation of rust, a chemical change has taken place.
In iron, the iron atoms are arranged in a metallic crystalline matrix. When rust occurs, oxygen bonds to the iron atoms (which where not chemically bonded to anything before) to create an oxide of iron.

Answer 2
