What is the Lewis dot structure of hco3-2?

Answer 1

I'm pretty sure that the bicarbonate ion, HCO3 has a negative one charge. assuming that you are looking for HCO3- the structure is a carbon double bonded to a oxygen and single bonded to two oxygens, one of which has the hydrogen attached.

the structure is hard to draw with simple text, but would look more or less like

O

l

[O=C-O-H]- {and of course each oxygen has the necessary electrons around it}

Answer 2

The bond structure of formic acid starts with the C atom in the center with one double bonded O, a singly bonded H and a single bond O. Both O atoms have two pair of dots, and the single bonded O has another single bond attached to an H atom.

Answer 3

H|. .C - O- . .|H(C has O, H, and H. H's are bonded once, while O is bonded twice with 2 electron pairs left over.)

Answer 4

Are you sure you're not talking about HCO3? HCO2 would be very unstable
