Question 1-
Yes , there is a missing charge in the structure. That is on Oxygen of carboxylate ion.
Explanation: oxygen in general requires 2 bonds to satisfy its electronic configuration. Thus there is only one bond in the oxygen of carboxalate ion due which it should have 1 negative charge.
Add Answer to:
Write in any formal charges not equal to zero. If there are none, please check the...
