Al I know is that the answer is not calcium oxide.I think that is the same reason the Statue of Liberty is green, her copper rusted and turned green. What is the name of that proccess?
the process is called oxidization. It is copper oxide. and copper can't rust - rust is actually IRON oxide.
Verdigris. It's copper acetate ~ mainly Cu (CH3COO)2.
Very simply it is 'oxidation'. Oxidation can be used when ever oxygen combines with a metal to form its' rust The new chemical (green stuff) is indeed 'copper oxide'. . . . and that is what happened to the Statue of Liberty. Get an A.
Copper(II) carbonate, also known as cupric carbonate, is the answer to your question. The Statue of Liberty gets its green color from the natural patina formed on its copper surface. A patina is a chemical compound formed on the surface of metal. Patinas form on metal from exposure to the elements.
