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.
HCO3, known as Bicarbonate (or hydrogen-carbonate) is a salt ion of Carbonic acid (H2CO3) .ormal levels â¦ are pH 7.35-7.45, PaCO2 35-45 and HCO3 22-26. If the values for these measurements are outside the normal ranges, then the body has an acid-base imbalance. If the PaCO2 is off, the condition is a respiratory issue. if the HCO3 is outside the normal range, then it is a metabolic issue.
