Question

a combination reaction occurs when chlorine (Cl2) and flourine (F2) reacts to form CIF3. if you begin with 10.00 g of chlorine and 10.00 g of flourine

a. write a balanced chemical equation for this reaction

b. which of the reactants is the limiting reagent

c. what is the theoretical yeild of ClF3

d. if you recovered 12.50 g of ClF3, wht is the percent yeild of this reaction?

PLEASE show all steps.

I HAVE:

a. Cl2+3F2 > 2ClF3

b limiting reagent is Cl2 - 0.07143 moles

c. 18.14 g of ClF3 - theoretical yield

d 68.91% yield

...Please help, is this correct

Explanation / Answer

yes your part a is correct , the reaction is

Cl2 + 3F2 ---> 2ClF3

b. Limiting reagent is Cl2 with moles = 0.08771

c. Theoretical yield is = 2 X 0.08771 moles of ClF3 = 92.45 X 2 X .08771 = 16.21 g

d. % yield is = (12.5 / 16.21 ) X 100 = 77.11 %
