Stoichiometry, Limiting Reactant, and % Yield Practice

What does percent yield indicate? The amount of product we should get The efficiency and accuracy of the lab The amount of product we actually got nothing When reacting Na with Cl2, we calculated that the theoretical yield should be 12.5 grams. Our actual yield was 13.0 grams. What is the percent yield? 100% 96% 104% 1.04 Al + H2SO4 --> Al2(SO4)3+H2In the above reaction, what is the ratio of moles ofH2SO4 to Al2(SO4)3 in the balanced equation? 1:1 3:1 1:3 2:3 C3H8 (g) + 5O2 (g) → 3CO2 (g) + 4H2O (g)When 2.5 mol of O2 are consumed in their reaction, _ mol of CO2 are produced 1.5 mol 2.1 mol 4.2 mol 2.0 mol CaC2 (s) + 2H2O (g) → Ca(OH)2 (s) + C2H2 (g)Production of 13 g of C2H2 requires consumption of _ g of H2O 9g 18g 4.5g 4.8g 3FeCl2 + 2Na3PO4 → Fe3(PO4)2 + 6 NaClIf 23 grams of iron (II) chloride reacts with 41 grams of sodium phosphate how much sodium chloride can be formed? (Find limiting reactant first!!) 21 g 44 g 43 g 22 g 3FeCl2 + 2Na3PO4 → Fe3(PO4)2 + 6 NaClIf 100. gFeCl2 reacts, and in the lab 87.0 g of NaCl is recovered, what is the percent yield? 87.1% 106% 94.6% 100% P4O10 + 6H2O → 4H3PO4 If 727 g ofP4O10 reacts with water, how many moles of H3PO4 are theoretically produced? 4010 mol 10.2 mol 40.1 mol _Fe2O3 + _C → _Fe + _CO2You add 28 grams of elemental carbon. You find the actual yield to be 181.2 grams of CO2. What is the percent yield of CO2? (Hint: calculate theoretical yield of CO2 first) 15.8% 6435% 209.2% 15.5 Theoretical yield = 73gActual yield = 62gCalculate the percent error 85% 15% 116% 76%
