Partial pressure of CO2 in blood.
The plasma (HCO3-) of an individual living at a high elevation is 18.5 meq/L. If this concentration of bicarbonate fully compensates the decrease in PCO2 found at the higher elevation, the PCO2 must be: 15, 18, 21, 31, or 37 mm Hg.
at pH 7.1, the ratio of plasma (HCO3-) to (CO2) is: 4:1, 8:1, 10:1, 20:1, 24:1.
trying to determine what an unknown substance is "liquid or solid"
I've been given a liquid and a solid and directed to try to determine what each substance is, whether it contains a ketone,alcohol,Carboxly group or any other functional group. What are some of the test I could perform to test for these functional groups?
Question for(Ota 103130) I have a white crystal/powder. It's melting point is (149C-150)range.I conducted several solubility test, it was unsoluble in water and unsoluble in(HCL)even after boiling. It was soluble in the following NaOH,sodium bicarbonate,and sulfuric acid. I know that acidic compounds soluble in (NaOH & NaHC03)ar ...continues

Determine the primary structure of the peptide
In trying to deduce a primary structure of an peptide sequence... When does a polypeptide NOT contain a free carboxyl group? Are all peptides linear (or can they have a cyclic C-terminus)? What happens when treatment of the intact peptide with 2,4-dinitroflourobenzene (followed by complete hydrolysis and chromatography) y ...continues
