Question

14 multiple choice 1 point copper (ii) nitride cu₂n cu₃n₂ cun cu₂n₃

Explanation:

Step1: Determine the charge of copper

Copper (II) has a charge of \(Cu^{2+}\).

Step2: Determine the charge of nitride

Nitride has a charge of \(N^{3 -}\).

Step3: Cross - multiply the charges

To form a neutral compound, we cross - multiply the magnitudes of the charges. For \(Cu^{2+}\) and \(N^{3 -}\), we get \(Cu_3N_2\) (because \(2\times3 = 3\times2\) to balance the charges).

Answer:

B. \(Cu_3N_2\)
