Question: please help with C D E and F a. What is the batanced inolecular equation for this preop tation reactian? Identafy the precpitate. Hint: Ute


a. What is the batanced inolecular equation for this preop tation reactian? Identafy the precpitate. Hint: Ute the salibidey nutea found in Chapter 4 to determine the pbyaical alatas of your products: Bed ture fo include the cormet fomulas for each compound, staichiometric coeficients, and plysical stades. b. Determine the limiting reactant uting ssoichiometric colculations. Show your work and include units. \# of moles CaCl2=2.0g/110.98g/mol =0.018mol \$ of moles K2CO3=2.9g/1is8.2g/mol =0.021mol limiting reactant: CaCl2 0. What is the theoretical yiold of the preoptate? Show your work and include \# of moles CaCl2=2.0g/110.98g/mol =0.018mol \# of moles K2CO3=2.9g/138.2g/mol =0.021anol limiting reactant: CaCl2 c. What is the theoretical yield of the precipitate? Show your work and include units. d. What is the actuat yield of the precipitate? e. What is the percent yield? Show your work and include units. f. Discuss TWO possible sources of error for your experiment - think about why your percent yield is less than or greater than 100%. ("Human error" is NOT an acceptable source of error-be specific!). Discuss TWO ways your experiment could be improved if it were to be repeated. Error source 1: Error source 2: Improvement 1: Improvement 2
