Answer

Explanation:

Step1: Determine sulfur's charge

In ionic compounds, sulfur (S) usually has a charge of 2-.

Step2: Balance charges in CuS

For the compound CuS to be neutral, if S has a 2 - charge, then copper (Cu) must have a 2+ charge to balance it out.

Step3: Determine nitrogen's charge

In ionic compounds, nitrogen (N) usually has a charge of 3-.

Step4: Balance charges in Fe₃N₂

Let the charge of iron be (x). In (Fe_3N_2), we have (3x+2\times(- 3)=0). Solving for (x): [ \begin{align*} 3x-6&=0\ 3x&=6\ x& = 2 \end{align*} ] So the charge of iron is 2+.
