Gastric juice is made up of substances secreted from parietal cells, chief cells, and mucous-secreting cells. the cells secrete hcl, proteolytic enzyme zymogens, mucin, and intrinsic factor. the ph of gastric juice is acidic, between 1-3. if the ph of gastric juice is 1.2, what is the amount of energy (δg) required for the transport of hydrogen ions from a cell (internal ph of 7.4) into the stomach lumen? assume that the potential difference across the membrane separating the cell and the interior of the stomach is –70.0 mv (inside of cells negative relative to the lumen of the stomach). assume that the temperature is 37 °c. the faraday constant is 96.5 kj·v–1·mol–1 and the gas constant is 8.314× 10–3 kj·mol–1·k–1. express your answer in kj/mol.

wher is the rest of the question

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2

c. orbital shape i hope this is correct
