In the text box provided, comment on the values of Ksp that you obtained in this experiment. Compare and contrast the values you obtained in pure water, in 0.01 M KIO3 both with and without including activity effects. Because Ksp should be independent of the solvent, we would expect the more accurate treatment of the data to have a smaller difference between the values obtained in pure water and in 0.01 M KIO3. Do your data show that Ksp is more nearly a constant when activity effects are included in the calculation?

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

it is stable as it is in group 0 which have full outer shells of electrons

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
