It is not organic chemistry

Answer 1

Ans fe object can be protected from rusting by connecting it with Cu because au has almost no fe content hence it cannot Just but can react with O₂. copper form its oxides which protect metal from rusting. Fe will get protection untie cu is present. Hence, if we use a long wire of ce with fe , it will Protect te from rusting for a long time than with a Short wire of cu Hence, we can conclude than nail can be protected from rusting by connecting it with a long au wire. -
