part c: draw a correct lewis structure for co₂.

Explanation:

Step1: Count valence electrons

Carbon has 4 valence electrons, and each oxygen has 6 valence electrons. So total valence electrons: (4 + 2\times6=16)

Step2: Arrange atoms

Carbon is the central atom (less electronegative than oxygen).

Step3: Distribute electrons

First, form single bonds ((C - O)). Each single bond uses 2 electrons. Then, distribute remaining electrons as lone pairs. But for (CO_2), the correct structure has double bonds. Carbon forms double bonds with each oxygen ((O = C = O)). Each oxygen has 2 lone pairs.

Answer:

(O = C = O) (with each oxygen having 2 lone pairs)
