I want to listen to some metal music. I need some good metal bands.
Metal Displacement reactions, more commonly calle Single Replacement reactions such as : 2Ag(NO3) + Cu = Cu((NO3)2 + 2Ag. Among many other applications: synthesis and electroplating.
In displacement reactions, the less reactive metal is replaced by more reactive metals. The reactivity of metals can be obtained from the reacivity series of metals. The displacement reactions can be used for electroplating, metal refining ect. For eg. if we have to electroplate an object with silver, we can use a solution of silver nitrate and iron. Ther more reactive iron displaces silver from the solution and free silver atoms are deposited on the object. The iron atoms go into solution as iron nitrate.
