Answer:
87.15%
Explanation:
To find percent yield, we can use this simple equation
Where "Actual" is the amount in grams actually collected from the reaction, and "Theoretical" is, well, the theoretical amount that should have been produced.
They give us these values, so to find the percent yield, just plug the numbers in.
So, the percent yield is 87.15%
An easy trick to remember how to do this is just to divide the smaller number by the bigger number and move the decimal back two places. If you have a percent yield greater than 100%, something is wrong in the reaction.
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
