2) Determine your percent yield of sodium chloride in reaction A. Show your work for each step. Write the balanced equation for reaction A - the reaction between sodium bicarbonate and hydrochloric acid. Using mass-to-mass stoichiometry, calculate the theoretical yield of NaCl for reaction A. Use your initial mass of sodium bicarbonate reactant as a starting point, along with the relevant mole-to-mole ratio from the balanced equation to perform this calculation. . Calculate your percent yield of sodium chloride product....
1. If 142 mg of triphenylmethanol (limiting reagent) reacts with excess Hbr, what mass of triphenylmethyl bromide should be formed? (theoretical yield) 0.0255 mol 2. If 110 mg of triphenylmethyl bromide is actually formed, what is the percent yield of the product?
Calculate the percent yield if you start with 0.18 mL trans-cinnamaldeyde and 0.617 g benzyltriphenylphosphonium chloride in 2 mL 10 N NaOH and isolate 0.206 g (E,E)-1,4-diphenyl-1,3-butadiene. Show ALL your calculations! (Hint: first you need to compare the moles of the substrates to know which substrate is the limited reagent. Then you calculate the percent yield by comparing the moles of the product with the theoretical yield (moles of the limited reagent).)
