Dear Student, Kindly refer to the complete solution. Feel free to ask if you face difficulty in understanding any part of the solution attached so that we can assist you in a better way.

Dear student 0 (a) [Cu(NH), ů firstly, write the name of ligand - NHgle. ammine since there are 4 ligands we will use tetra".
