Which of these molecules and polyatomic ions cannot be adequately described using a single Lewis structure? Check all that apply. CO3 2-COH2HCNO3NH4+OF2

Answer;

CO3^2 - and O3

Explanation; Ozone, O3 is a molecule composed of three oxygen atoms joined together. Two oxygen atoms joined together form the basic oxygen molecule O2. A polyatomic ion is a charged particle which has two or more atoms held together by covalent (sharing of pairs of electrons) bonds. Carbonate (CO3^2-) is an example of polyatomic ion. It can not be adequately described using Lewis structure.
