Homework software response: The correct answer is N≡NX+−NX2− N ≡ N X + − N X 2 −. That's all it says. My understanding of why this is valid is that this gives a formal charge of (0) ( 0) for every atom, as opposed to averaging out to that. I suppose the second form makes sense, as it's a lower formal charge on the central atom.azulode (@azulode_) no TikTok |3.1M curtidas.111.4K seguidores.viu meu perfil e não seguiu nariz caiu - Contato: [email protected] ao último vídeo de azulode …Dr Christian M Azode, APRN-PMHNP-BC is a Medicare enrolled "Nurse Practitioner - Psychiatric/mental Health" in Phoenix, Arizona.
