Consider one resonance structure for the azide ion, N3-1 :   What is the formal charge on each nitrogen atom in this resonance structure? Enter your answer as a number preceded by the appropriate charge (+ or -), if applicable.  If the formal charge is zero, enter 0 . formal charge of left N  [a] formal charge of middle N  [b] formal charge of right N  [c]

Draw out the Lewis structures for H₂CO3, HCO3, and CO32-. Then determine the maximum number of equivalent resonance structures for each species. Note that carbon is the central atom in all three cases. If the molecule contains hydrogen atoms they are attached to oxygen atoms. Only count the best structures. For example, A structure with really bad formal charges should not be counted. The molecule H₂CO3 has The molecule HCO3 has The molecule CO3²- has equivalent Lewis structures. equivalent Lewis structures. equivalent Lewis structures.

The Lewis structure for the chlorate ion is :0: Calculate the formal charge on the chlorine (Cl ) atom. Express your answer as an integer. • View Available Hint(s) formal charge on Cl = Submit Part B Calculate the formal charge on each of the oxygen (O) atoms labeled a, b, and c in the following Lewis structure. :0: Express your answers as integers separated by commas. • View Available Hint(s) formal charge on Oa , Ob , Oc = Submit ormal charges to predict the most stable structure he interactive activity shows how to calculate the formal charge of atoms in a structure. These formal charges can be used to predict the resonance structure that contributes most to the stability of a molecule or ion. The struc enerally the most stable.
