Calculate the following thermodynamic parameters for reaction between cytochrome c is and complex iv.
what is the ? ? value for the oxidation of cytochrome c by the cua redox center in complex iv when the ratio of cyt c (fe2+)/cyt c (fe3+) is 20 and the ratio of cua (cu2+)/cua (cu+) is 3? (express your answer in volts using three significant figures.) note: ? 0'(cua (cu2+)+e-? cua (cu+)) = 0.245 v at 25ºc.

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

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
