(a)


so the formula for barium azide is BaN6

barium azide is an ionic compound of Ba2+ and [azide]–

so Ba[azide]2 = BaN6 which means the chemical formula of azide ion is [N3]–


(b) Three resonance structures of azide ion are

@William C: Nice job. What method do you use to be able to type the structures of the resonance forms? Is it some sort of copy and paste? Otherwise, not sure how you format them on this platform. Thanks.

Thanks! It turns out that ⁻:N̈=N̈–N̈: ↔ ⁻:N̈=N=N̈:⁻ ↔ :N̈–N̈=N̈:⁻ is possible as plain text. The trick was finding the N̈ character via the Google search "capital N with diaeresus". Putting the + on top of the central N in the major resonance structure required lining up and grouping text boxes in MS Word. The resulting text box was then copied from Word and pasted into the answer on Wyzant. (Were it not for the frustrating Wyzant size limitation imposed on inserted figures I could have simply used ChemDraw for the resonance structures.)
