Answer: Theoretical yield of produced by 8.96 g of S is 33.6 g
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of produce = 3 moles of
Thus 0.28 moles of will produce=
of
Mass of
Thus theoretical yield of produced by 8.96 g of S is 33.6 g
Answer:
SEPARATION SCHEME FOR CATIONS
GIVEN CATIONS :
Step 1: Add of
to the mixture solution
Result : This would cause a precipitate of to be formed
Reaction :
Step 2 : Next is to remove the precipitate and add to the remaining
solution in the presence of of HCl
Result : This would cause a precipitate of to be formed
Reaction :
Step 3: Next remove the precipitate then add of aqueous
, process the solution in a centrifuge,when the
process is done then sort out the precipitate from the solution
Now this precipitate is and the remaining solution
contains
Next take out the precipitate to a different beaker and add HCl
to it this will dissolve it, then add a drop of this will
form a precipitate which will have the color of
blood indicating the presence of
Reaction :
Now the remaining mixture contains
