Zn(NO3)2+NH3*H2O->Zn(OH)2+NH4NO3

Zn(OH)2+HCl->ZnCl2+H2O

Answer 2

Balancing the Chemical Equation for the Transformation Zn-Zn(NO3)2-Zn(OH)2-ZnCl2

To balance the chemical equation for the transformation of Zn to ZnCl2, we need to consider the reactions involved at each step of the transformation.

Step 1: Zn to Zn(NO3)2 The balanced chemical equation for the reaction of Zn with HNO3 to form Zn(NO3)2 is: ``` Zn + 2HNO3 -> Zn(NO3)2 + H2 ```

Step 2: Zn(NO3)2 to Zn(OH)2 The balanced chemical equation for the reaction of Zn(NO3)2 with NaOH to form Zn(OH)2 is: ``` Zn(NO3)2 + 2NaOH -> Zn(OH)2 + 2NaNO3 ```

Step 3: Zn(OH)2 to ZnCl2 The balanced chemical equation for the reaction of Zn(OH)2 with HCl to form ZnCl2 is: ``` Zn(OH)2 + 2HCl -> ZnCl2 + 2H2O ```

By following these balanced chemical equations, the transformation from Zn to ZnCl2 through the intermediate steps of Zn(NO3)2 and Zn(OH)2 can be achieved.
