resonance of HCO3^- and sigma/pi bonds

lorka150

Are two equivalent resonance forms HCO3^- like this?
O
//
O - C
\
O - H


O - H
/
O - C
\\
O


Both structures have brackets and a -.
Also, each O on the left has six dots, the O on the double bond has four, and the O on the H has four as well.

Are there four sigma and 1 pi?

Thanks.
