What is the net ionic equation of 2K (s) + Cd(NO3)2 (aq) --> 2K(NO3) + Cd ?

2K^+(aq) + 2NO3^-(aq) —> 2K(NO3)

Explanation:

2K (s) + Cd(NO3)2 (aq) —> 2K(NO3) + Cd

We can obtain the net ionic equation for the above reaction as follow:

Cd(NO3)2 will dissociate in solution as follow:

Cd(NO3)2 (aq) –> Cd^2+(aq) + 2NO3^-(aq)

K(s) –> K^+(aq)

Therefore:

2K (s) + Cd(NO3)2 (aq) —> 2K(NO3) + Cd

=>

2K^+(aq) + Cd^2+(aq) + 2NO3^-(aq) —>

2K(NO3) + Cd^2+(aq)

We shall cancel out Cd^2+ from both side of the equation to obtain the net ionic equation as shown below:

2K^+(aq) + 2NO3^-(aq) —> 2K(NO3)

Therefore, the net ionic equation for the reaction is

2K^+(aq) + 2NO3^-(aq) —> 2K(NO3)

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

they are all solids.
