Both men and women have 24 ribs, twelve on each side. Each rib is attached to a spinal bone (thoracic vertebra) in the back. The first seven pairs of ribs join the breastbone (sternum) in the center of the chest. The front ends of the eighth, ninth, and 10th pairs are connected to the ribs above them.
No, H2CO3 is an aquous solution of carbon dioxide gas (CO2). It can also be 'written' as (CO2+H2O) or (CO2.H2O) or (CO2,aq) = hydrate of carbon dioxide and its chemical name â¦ : carbonic acid.
== From Pisgahchemist: The catch is that there are NO molecules of H2CO3 in aqueous solution. What we call carbonic acid is actually CO2 dissolved in water in equilibrium with H+ and HCO3^-. Carbonic acid is a weak acid, and so you might think that there would be nonionized H2CO3 molecules. That simply isn't the case.
