The number of copper atoms is 10,699.10e23.
CuCl2 is the product.
The answer is 7,44.10e-6 mol.
NiCl2 + 2Na --> 2NaCl + Ni
Cl refer to chlorine atoms. They don't exist naturally in that form. Rather, Cl2 refer to chlorine molecules, and they exist as that form in nature.
There are three atoms.One copper atom and two chlorine atoms.
CuCl2 is a compound or molecule with 3 atoms.
It is Copper(II) Chloride = CuCl2
Cobolt dichloride is made up of one cobalt atom and two chlorine atoms. This gives it a total molar mass of 129.84 grams per mole.
K[CuCl2]
The number of copper atoms is 10,699.10e23.
How many Chlorine (Cl) atoms there are. Since Cu has a valence shell of 2, it needs to bond with 2 Chlorine ions in order to create complete valence shells for the molecule.
Examples: CH4 and C2H6, CuCl and CuCl2, NaO and Na2O, etc.
CuCl2 is the product.
CuCl2
CuO + 2HCL - CuCl2 + H2O
cu(II) + 2agcl --> 2ag+cucl2
