Copper can exist in two states of oxidation.
However,
NO3 is charged (-1) ... hence the copper is charged ... right (+1)
+2 oxidation state for the Copper. -1 for the Chloride
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.

CuCl2
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.

K[CuCl2]
There are two different copper chloride compounds, due to the two possible 'oxidation state numbers' (+1 and +2):CuCl cuprous chloride, Cu(I) chloride, mono-valent Copper chlorideCuCl2 cupric chloride, Cu(II) chloride, bi-valent Copper chloride
+2 oxidation state
CuCl2

CuCl2.
A Roman number in the name of an ionic compound gives the absolute value of the oxidation number of that element in the compound which immediately precedes the Roman number. This is most common with cations of elements, such as copper and cobalt, that can form stable cations in more than one oxidation state. Copper(II) chloride, for example as the formula CuCl2 while copper(I) chloride has the formula CuCl.
Cupric is used when copper is in a +2 oxidation state while cuprous is used when copper is in a +1 oxidation state.
2HCl + Cu -> CuCl2 + H2 Assuming that it's Copper (II). CuCl2=Copper Chloride
Five: 0 (elementary), +1, +2, +3, +4
