because copper dissolves in salt.

Depending on the classification of the metal a specific factory buys it! For example, copper scrap goes to recycling copper factories to be renewed, same goes with other materials :)
Copper is a metal that can turn green when exposed to the elements and develops a patina over time. This greenish hue is due to the oxidation process that occurs on the surface of the copper.
The product of iron and copper (II) sulfate is iron (II) sulfate and copper. This reaction is a single displacement reaction where the more reactive metal (iron) displaces the less reactive metal (copper) from the compound.
Copper metal turns green when exposed to vinegar due to a chemical reaction that forms copper acetate. This green substance is known as verdigris and is a common patina that forms on copper surfaces exposed to acidic environments.
The metal you are referring to is likely copper. When exposed to air, copper reacts with oxygen to form copper oxide, which gives the metal a dark black or greenish color. This process is known as oxidation.
Any metal that will conduct electricity. Steel works fine, since it is strong. A ground rod driven into the ground and connected to the lightning rod with a wire or cable. The ground rod is usually copper clad (or plated) steel.
Yes, because the part of the plug that goes into the power point is metal, and the bit around it is plastic.
The scale that forms on heated copper is typically a layer of copper oxide, which is a compound of copper and oxygen. This scale is a darker color than the original copper metal. The scale is also more brittle and can flake off easily compared to the ductile and malleable nature of the copper metal itself. Additionally, the scale may provide some protection against further oxidation of the underlying copper metal.
Cu(s) + 2AgNO3(aq) --> 2Ag(s) + Cu(NO3)2(aq)According to the metal activity series, copper is more reactive than silver, so the copper will replace the silver in the silver nitrate compound.https://en.wikipedia.org/wiki/Reactivity_seriesThe silver metal will precipitate out of solution, forming along the piece of copper, which goes into solution, combining with the aqueous nitrate ion. If this reaction goes to completion, all of the copper will go into solution as copper(II) nitrate, and all of the silver metal will precipitate out of solution.
When the price copper goes down, the Chile economy also goes down. The Chilean economy relies heavily on copper; almost 20% of its exports and GDP is based on copper, so when it goes down, the economy is effected as it goes down.
1. There is not much of it 2. It does not change - if buried 2000 years ago and now dug up it will still look the same. Silver goes black, iron goes rusty, copper goes green, and so on
