Cu is the chemical symbol for copper, while AgNO3 is the chemical formula for the inorganic compound silver nitrate. Copper is an element with the atomic number 29. Silver nitrate is composed of one silver, one nitrogen and three oxygen atoms.
Silver nitrate can be synthesized by reacting silver with nitric acid. The by-product of this synthesis is water and oxides of nitrogen. Copper is found in the Earth's crust at 50 parts per million. Copper is extracted by mining for natural copper and copper sulfides. The most abundant copper sulfides are chalcopyrite and chalcocite, which are also known as copper ore minerals. Once mined, copper is extracted from them through a variety of electrochemical and physical processes.
