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.
Oxidation number of P in H3PO3 is +3. To calculate the oxidation number H= 1 except when bonded to metal O is -2 except when bonded to F The sum of all of the oxidation â¦number on a molecule /ion is equal to the charge so as H3PO3 is a neutral molecule:- 0 = OxP + 3OxH + 3OxO = Oxp + 3 + (-6) Oxp = +3 H3PO3 is phosphorus acid.
