There are three atoms.One copper atom and two chlorine atoms.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
2
Exactly one million. insanely small, right?
I believe it is 4. 1A+1G+2O 1+1+2=4
Yes, it is possible to split an atom in a molecule (nuclear fission) and it is possible to split an atom from a molecule (chemical dissociation). In the first case, the processes of nuclear reactions have no respect for ordinary chemistry at all. If uranium is going to undergo fission, it does so, regardless of whether it is in a molecule or not. In the second case, it happens all the time, as when table salt is dissolved in water, and the atoms ionize and go their separate ways.
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]
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
Under normal conditions CuCl2 can exist in either a solid state or in aqueous solution.
NiCl2 + 2Na --> 2NaCl + Ni
