Given question is incomplete. The complete question is as follows.
Gastric juice (pH 1.5) is produced by pumping HCl from blood plasma (pH 7.4) into the stomach. Calculate the amount of free energy required to concentrate the H in 1 liter of gastric juice at 37 degree of centigrade. Under cellular conditions, how many moles of ATP must be hydrolyzed to provide this amount of free energy? the free energy change for ATP hydrolysis under cellular conditions is about -58 kJ/mol. Ignore the effects of the transmembrane electrical potential.
Explanation:
The given data is as follows.
Gastric juice pH = 1.5, blood plasma pH = 7.4
Temperature = = (37 + 273) K
= 310 K
Now, relation between pH and concentration of hydrogen ions is as follows.
pH =
At pH = 1.5, we will calculate the as follows.
=
= M (
)
At pH = 7.4, we will calculate the as follows.
=
= M (
)
Also,
=
= 35 kJ/mol
So, the amount of ATP necessary to provide 35 kJ is as follows.
= 0.6 mol
Therefore, we can conclude that 0.6 moles of ATP must be hydrolyzed to provide this amount of free energy.
Answer:
Answers are bellow.
Explanation:
The element with electron configuration 1s22s22p63s1 belong I A group in the periodic table and it is sodium because it loses one electron.
We have periodic table in attachments.
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na+ cation. Its only stable isotope is 23Na.
The free metal does not occur in nature, and must be prepared from compounds.
It is soft metal, reactive and with a low melting point.
