Sol t-Laboratory Questions e spaces provided for the answers and additional paper if necessary. ed on your data and observations: Which of the reactants in your experiment was the limiting reagent? Briefly explain. Which of the reactants in your experiment was present in excess? Briefly explain. Based on the empirical formula you determined for copper chloride, complete the following equation for the major reaction in this experiment. Zn (s, silvery-white) aq, blue) ZnCl2(aq) Cu (s, reddish Based on the mass of zn reacted and the in calculate the theoretical yield of Cu for equation 2. (1), each of your determinations, using Equation 15. 1 mol Zn B mol Cu 63.55 g Cu (Eq. 15 theoretical yield of Cu g mass of Zn, g 65.38 g Zn A mol Zn 1 mol Cu where A and B are the coefficients for zn and Cu respectively in the equation in 2.@ Determine the percent yield of Cu for each of your determinations, using Equation actual yield of Cu, g (100%) percent yield of Cu, heoretical yield of Cu, g
Explanation / Answer
ANSWER
Zn+cucl2===> zncl2 +cu so here limiting reagent ==> cucl2 , excess are ===>zn
