Vinegar and salt solution, the acetic acid from the vinegar dissolves the copper oxide. The copper from the copper oxide stays in the liquid
No reaction, because iron is a more active metal than copper. This means that copper cannot reduce iron from its salt.
No. Copper is an element; meaning it is not made up of other metals.
Because iron is more reactive than copper, as can be seen on an activity series of metals. Refer to the related link for more information and an activity series of metals.
A magnet attracts the Iron Filings and not the salt and sand (which do not contain Iron). Because iron is magnetic, salt and sand are not. Therefore the magnet only picks up the magnetic objects, in this case iron.

Copper is less reactive than iron, therefore iron will exist as an aqueous ion and copper will be an elemental metal. See the "reactivity series for metals."

Iron does not displace sodium from a salt solution because it is not reactive enough. Iron does, however, displace Cu from a copper sulphate solution.
No. Copper is an element; meaning it is not made up of other metals.

Trace-mineral salt is salt that contains trace minerals including Selenium, Copper, Iron, Manganese, Molybdenum, Iodine, Cobalt, etc.
Ecuador has mines of gold, silver, copper, coal, salt, lead, iron, and zinc.
