Nitrate, NO3─, and sulfate, SO4─, are anions that display resonance. Resonance occurs when there Lewis structures to describe the distribution of electrons in a substance. The best description of the substance is of the Lewis structures. a. is one reasonable, one b. are multiple reasonable, one c. are multiple reasonable, an average d. are no reasonable, none
