What factors during the experiment caused the percent yield to be different than 100%? What impurities may be present in the final product (look at the spectroscopic data for evidence of this), and how does that effect the percent yield calculation? I got 64% for the percent yield.

What factors during the reducing bezil experiment caused the percent yield to be different than 100%? What impurities may be present in the final product and how does that effect the percent yield determination?

2. Ethyl chloride is prepared by the reaction of chlorine with ethane according to the following equation: C:Ho(g) + Cl2(g) – CH$CI(g) + HCl(g) Ethane Ethyl chloride a) Write the balanced chemical equation. Show proof of completion. b) When 5.6 g of ethane is reacted with excess chlorine, determine its theoretical yield c) Calculate the percent yield of ethyl chloride if experimental results indicated that 8.54 g of ethyl chloride had formed.

Consider the reaction below. A student takes 53.12 grams of Fe and mixes it with 37.12 grams of S – then they heat the mixture to cause the reaction to occur. Use math and words to prove which of these reagents is the limiting reagent in that reaction.

My theoretical yield of beryllium chloride was 12.4 grams.  In an experiment, if my actual yield was 7.8 grams, what was my percent yield?   Be   +  2 HCl -----> BeCl2   +  H2
