licl
The flame color of CuCl2 is blue-green. This color is often observed when copper compounds are heated in a flame.
CuCl2 is a type II compound. In type II compounds, the cation can have multiple oxidation states, and the charge of the cation must be determined from the compound's formula. CuCl2 contains copper in the +2 oxidation state.
The formula rm CuCl3 is not reasonable because copper typically forms stable compounds with a +1 or +2 oxidation state. The correct formula for a stable copper chloride compound would be rm CuCl or rm CuCl2.
The anion in CuCl2 is chloride (Cl-).
Cu + HNO3 = CuNO3 + H2 or copper nitrate and hydrogen gasCu + 4 HNO3 --> Cu(NO3)2 + 2NO2 + 2H2OThe brown colored gas that comes of the reaction is NO2.
Silver chloride (AgCl) is the most stable compound out of the ones listed. This is because silver (Ag) is a transition metal with a filled d orbital, which contributes to its stability compared to the other compounds. The other compounds listed (CuCl2, AlCl3, LiCl) are less stable due to the electronic configuration and charge distribution of their respective elements.

CuCl2 and Al(s)
There are many compounds that don't contain nitrogen: CO2, NaCl, H2O, C6H6, CuCl2...
These compounds are CuSO3 CuS CuCl2..
The chemical equation is:2 Al +3 CuCl2 = 3 Cu + 2 AlCl3

When you add CuCl2 to Al, a single displacement reaction occurs where Al replaces Cu in the compound to form AlCl3 and Cu. This reaction is typically exothermic and may result in the release of heat or even sparks due to the high reactivity of aluminum with copper chloride.
Examples: CH4 and C2H6, CuCl and CuCl2, NaO and Na2O, etc.
