Chemistry Help: Very Bottom of Page are the questions and thedata is above the Data Analysis Questions #1 #2 #3 #4 ? Help pleaseshow work so I could understand how you solved the questions.
The procedure for Experiment 8 and the subsequent data analysis will be modified slightly from what is indicated in your lab book. Rather than being given a mixture of unknown composition, you will be told the amounts of CaCl2'2H20 and K2C204,H20 that were added to your sample. Based on the information given, you can perform the exercises described below. Precipitation of CaC2CO4H20 from Salt Mixture Unknown number Reactant masses (g) Mass of filter paper (g) Mass of filter paper and CaC204 H20 (g). Mass of CaC204 H20(g) Determination of Limiting Reactant Based on Chemical Tests Results of adding: Limiting reactant (write complete formula) Excess reactant (write complete formula) Data Analysis Based on the reactant masses given above, determine the limiting reactant. Compare the result obtained with the result observed using the chemical tests. Note that since there are several methods possible for determining limiting reactants, you may want to combine this step and the next (item 2). You make the decision based on what procedure you are most comfortable with. Based on the reactant masses given above, determine the theoretical yield (in grams) of CaC204-H20 Calculate the mass (in grams) of excess reactant that was not consumed in the reaction. From the answer in part 2 and the mass of CaC2CO4 H20 obtained from your procedure, calculate the percent yield of CaC204 H20. Comment on the results. Include possible explanations for low or high results.
