Cu + MgCl2 --> no reaction
In order for a single replacement/displacement reaction to take place, the free metal must replace the bonded metal in the compound. However, according to the reactivity series of metals, copper does not replace magnesium, however magnesium would replace copper in a compound. Mg + CuCl2 --> Cu + MgCl2. Refer to the related link for a reactivity series of metals.
CO2 is not an equation, so it cannot be balanced. It is a chemical formula.
The chemical equation is:2 Al +3 CuCl2 = 3 Cu + 2 AlCl3
For the molecular balance of the equation it would be: CuSO4 (aq) + Na2S (aq) = CuS (s) + Na2SO4 (aq). For the net ionic balance of the equation it would be: Cu2+ (aq) + S2(aq) = CuS (s).
Cu(I), cuprous, Cu+.
copper (II) sulfate is CuSO4 ; Zinc sulfate is ZnSO4 Zn + CuSO4 --> ZnSO4 + Cu
Zn + CuSO4 --> ZnSO4 + Cu
The chemical equation is:2 Al +3 CuCl2 = 3 Cu + 2 AlCl3
CO2 is not an equation, so it cannot be balanced. It is a chemical formula.
To balance the equation CuSO4 + Na, follow these steps: Write down the unbalanced equation: CuSO4 + Na → ? Determine the products of the reaction based on the elements involved: CuSO4 + Na → Cu + Na2SO4 Now, balance the equation by ensuring that the number of atoms for each element is the same on both sides: CuSO4 + 2Na → Cu + Na2SO4
The balanced equation for the reaction between zinc (Zn) and copper (II) bromide (CuBr2) is: Zn + CuBr2 → ZnBr2 + Cu
oxidation
To balance the chemical equation for the reaction between iron and copper(II) nitrate yielding iron(II) nitrate and copper, you would need to make sure there are the same number of each type of atom on both sides of the equation. The balanced equation is: Fe + Cu(NO3)2 -> Fe(NO3)2 + Cu
Cu + 2NH3 → [Cu(NH3)2]+
mg + CuCl2 + MgCl2 + Cu Mg + Cu^+2 = Mg^+2 + Cu
Cu-------Cu2+ + 2 e-
PbCl2 + Cu
There is no equation because there is no reaction.
