The final answer would be 2Cu O2---> 2CuO
Cu + HNO3 = Cu(NO3)2 + NO + H2O
The chemical equation is:2 Al +3 CuCl2 = 3 Cu + 2 AlCl3
Cu-------Cu2+ + 2 e-
Zn + CuSO4 --> ZnSO4 + Cu
PbCl2 + Cu
No. In concentrated nitric acid, the reaction produces copper (II) nitrate, nitrogen dioxide (a toxic, brownish colored gas) and water. The reaction is as follows: Cu(s) + 4HNO3(aq) --> Cu(NO3)2(aq) + 2NO(g) + 2H2O(l) In diluted nitric acid, the reaction produces copper (II) nitrate, nitric oxide (NO), and water. The reaction is as follows: 3Cu(s) + 8HNO3(aq) --> 3Cu(NO3)2(aq) + 2NO(g) + 4H2O(l) (Source: www.angelo.edu)
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
Cu + S = CuS
Cu + 4HNO3 ----->Cu(NO3)2 + 2NO2 + 2H20
To balance the equation Cu + Cl2 → CuCl2, you need to make sure there are the same number of atoms on each side: 2 Cu atoms on the left, 2 Cl atoms in CuCl2, and 2 Cl atoms in Cl2. So, the balanced equation is Cu + Cl2 → CuCl2.
CO2 is not an equation, so it cannot be balanced. It is a chemical formula.
The balanced equation for the reaction between zinc (Zn) and copper (II) bromide (CuBr2) is: Zn + CuBr2 → ZnBr2 + Cu
