Solution: Scooby Doo went out to look at his Doghouse but he discovered that the roof which was made of a sheet of copper metal had changed from its original shiny metallic “penny” bright color to a shade of deep green. The original copper metal had gradually been covered by a green patina which is usually a mixture of copper chlorides, copper carbonates and copper sulfides. Is the observation that this patina forms a chemical or a physical property?   a. chemical b. physical c. both d. neither e. not enough information given to make a determination
