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 l of gastric juice at 37 degrees c. under cellular conditions, how many moles of atp must by 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.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
