question 5 (1 point)

the correct names of ca3n2
and ba3n2 are:

1. calcium nitrogen and barium nitrogen
2. cobalt nitride and beryllium nitride
3. calcium nitride and barium nitride
4. carbon nitride and boron nitride

Explanation:

• For ionic compounds like \(Ca_3N_2\) and \(Ba_3N_2\), we name the cation first (calcium \(Ca^{2 +}\) and barium \(Ba^{2+}\) here) and then the anion. The anion \(N^{3 -}\) is named nitride.
• Option 1 is incorrect because the anion is mis - named (should be nitride, not nitrogen).
• Option 2 has wrong cations (cobalt \(Co\) and beryllium \(Be\) instead of calcium and barium).
• Option 4 has wrong cations (carbon \(C\) and boron \(B\) instead of calcium and barium).

Answer:

1. Calcium nitride and Barium Nitride
