Answer 2

Equations for the given transformations: CuO - Cu - CuCl2 - Cu(NO3)2 - Cu - Cu

To determine the equations for the given transformations, let's break down each step:

1. CuO to Cu: - The transformation from CuO to Cu involves the reduction of CuO to Cu. - The balanced equation for this transformation is: CuO + H2 → Cu + H2O.

2. Cu to CuCl2: - The transformation from Cu to CuCl2 involves the reaction of Cu with chlorine gas. - The balanced equation for this transformation is: Cu + Cl2 → CuCl2.

3. CuCl2 to Cu(NO3)2: - The transformation from CuCl2 to Cu(NO3)2 involves the reaction of CuCl2 with nitric acid. - The balanced equation for this transformation is: CuCl2 + 2HNO3 → Cu(NO3)2 + 2HCl.

4. Cu(NO3)2 to Cu: - The transformation from Cu(NO3)2 to Cu involves the reduction of Cu(NO3)2 to Cu. - The balanced equation for this transformation is: Cu(NO3)2 + H2 → Cu + 2HNO3.

5. Cu to Cu: - The final transformation from Cu to Cu is simply the element itself. - There is no chemical reaction involved in this step.

Therefore, the complete set of equations for the given transformations is as follows:

1. CuO + H2 → Cu + H2O 2. Cu + Cl2 → CuCl2 3. CuCl2 + 2HNO3 → Cu(NO3)2 + 2HCl 4. Cu(NO3)2 + H2 → Cu + 2HNO3 5. Cu

Please note that these equations represent the chemical transformations described, but they may not necessarily represent the actual experimental conditions or reaction mechanisms.
