Consider the formate ion, hco2−, which is the anion formed when formic acid loses an h+ ion. the h and the two o atoms are bonded to the central c atom.

The lewis structure of the formate ion is shown in the attached picture.

Explanation:

The formate ion has 1 atom of Hydrogen, 1 atom of Carbon and 3 atoms of Oxygen.

The total amount of electrons involved in the structure are:

1 e⁻ (from Hydrogen) + 4 e⁻ (from Carbon) + 2 × (6 e⁻) (from Oxygen) + 1 e⁻ (ion's charge)= 18 e⁻

The central atom is C. The best Lewis structure has a double bond on one oxygen and the negative charge on the other oxygen.

The structure is shown in the attached picture.

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
