Write chemical equations for the five reactions described:

The first reaction involves the oxidation of copper with nitricacid, resulting in a blue-green colored copper (II) nitrate,Cu(NO3)2, solution.
The second reaction involves adding sodium hydroxide. Thisresults in a double replacement or precipitation reaction producesa milky-blue copper (II) hydroxide solid.
The third reaction involves decomposition of the of thehydroxide compound to a black copper (II) oxide solid whileapplying heat.
After filtering the oxide, sulfuric acid is added to the solidto produce a blue copper (II) sulfate solution in a doublereplacement, or more specifically an acid-base reaction.
Finally, solid elemental copper is recovered through a singlereplacement reaction by the addition of zinc metal filings.
