1. Statue of Liberty was actually of Brown colour. It is placed on a island. After some years it's colour started changing into green due to it's exposure to air and water around it.
The equation is an Oxidation Reaction.
Cu+O2+H20+CO2→CuCO3+Cu(OH)2
2. Iron tables are not as hard as iron metal because the tablets are made up of extremely minute quantity of Iron MOLECULES.
