please show all work

each letter is a question, and u have to draw out the lewis structure of each question

3. (18 pts) In the box, draw a geometrically correct Lewis structure of the major resonance contributor (most stable resonance structure) for the ions depicted below. Show all bonds, lone pairs, and charges. (a) Borate trianion (BO33) (b) Nitrate anion (NO3)Wade 8,17(b); Wade 9, 1-7a (c) Carbonate dianion (CO32) (d) Nitrite anion ( NO2) Wade 8, 1-7b. Wade 9, 1-7d, Wade 8, 1-7c, Wade 9, 1-7e 2019 practice exam (e) Isocyanate anion ( NCO) (f) Formate anion (HCO2) Wade 8, 1-15a; Wade 9, 2-10a
