For the following reaction, 6.73 grams of hydrochloric acid are mixed with excess barium hydroxide. The reaction yields 15.5 grams of barium chloride.
2 HCl (aq) + Ba(OH)2 (aq) = BaCl2 (aq) + 2 H2O (l)
(1) What is the theoretical yield of barium chloride ?
grams
(2) What is the percent yield for this reaction ?

Best ResponseYou've already chosen the best response.1gram mol weight (gmw) = sum of atmic weights of all the elemnts in the molecule so, gmw of HCl = at. wt. of H + atomic wt. of CL

Best ResponseYou've already chosen the best response.1at. wt. of Cl = ? you have to refer to your Preiodic table

Best ResponseYou've already chosen the best response.117 is the "atomic number" of Cl and 35.5 is the atomic wt.

electrokid

Best ResponseYou've already chosen the best response.1good, so, gmw of HCl = 36.5 what this means is that 1mole of HCl weighs 36.5g (g=grams)

Best ResponseYou've already chosen the best response.1similarly, for BeCl2... notice that there are two atoms of chlorine

Best ResponseYou've already chosen the best response.1practice to write it clearly.. gmw of BaCl2 = ___ + ___ + ____ = ____g

Best ResponseYou've already chosen the best response.0sorry I got 137 is the atomic number for Ba and 35 for Cl

electrokid

Best ResponseYou've already chosen the best response.1no.. atomic number = number of protons in the nucleus of an atom atomic mass number = total number of protons + neutrons in the nucleus of an atom

Best ResponseYou've already chosen the best response.1ok so gmw of BaCl2 = ?

Best ResponseYou've already chosen the best response.0I added the two 137+ 35

Best ResponseYou've already chosen the best response.1good now back to step 2... summarize our values

electrokid

Best ResponseYou've already chosen the best response.1you see.. those are just numbers.. I cannot help you unless you put meaning to them. gram mol wt of HCL = gram mol wt of BaCl2 =

Best ResponseYou've already chosen the best response.1now, using step 1, 2 moles of HCl  yield > 1mole BaCl2 i.e, 2* gmw of HCL  yields > 1*gmw of BaCl2

Best ResponseYou've already chosen the best response.12*_ = __ g of HCl  > ____g BaCl2

toxicsugar22

Best ResponseYou've already chosen the best response.002*36.5 = 73 g of HCl  > 172g BaCl2

electrokid
 one year ago
Best ResponseYou've already chosen the best response.1so, 73g HCl > 172g BaCl2 (Theoretical) so, 6.73g HCl  should yield how much? (we have 6.73g HCl and Expected BaCl2 is?)

electrokid

Best ResponseYou've already chosen the best response.1no.. HCl is our "reactant"..... BaCl2 is our product

electrokid

Best ResponseYou've already chosen the best response.1ok, so, 73g HCl  reacts to give us (yield) > 173g of BaCl2 how much HCl do we have in our reaction? (this part from the given question)

Best ResponseYou've already chosen the best response.06.73 is how much HCI WE HAVE

electrokid

Best ResponseYou've already chosen the best response.1so, if 73g HCl  provides > 173g BaCl2 then 6.73g HCl  should provide > ____g of BaCl2 this is a simple ratio..

Best ResponseYou've already chosen the best response.1..... \[{6.73 \times 173 \over 73}=?\]

Best ResponseYou've already chosen the best response.0I had to rethimk the problem

electrokid

Best ResponseYou've already chosen the best response.1good. then THIS is your theoretical yield i.e., in theory, that 6.73g of HCl should give us with 15.94g of BaCl2

Best ResponseYou've already chosen the best response.0part B. is where we do actual yield times theroicatl yield / 100

electrokid

Best ResponseYou've already chosen the best response.1(b) % yield = (actual yield) * 100 / (theoretical yield) this value must be less than 100 actual yield = given in problem theoretical yield = calculated above

Best ResponseYou've already chosen the best response.0so 15.5 times 100/ 15.94 =97.23
