Since KI is the limiting reactant, you can use that to figure out how many grams of Pb(NO 3) 2 will react and how many grams of KNO 3 will be made. 10.0 g KI x 1 mole KI x 1 mole Pb(NO 3 ) 2 x 331.22g Pb(NO 3 ) 2 = 9.98g Pb(NO 3 ) 2 will be used up. Answer the following questions: 9. The percentage composition of acetic acid is found to be 39.9% C, 6.7% H, and 53.4% O. Determine the empirical formula of acetic acid. 10. The molar mass for question #9 was determined by experiment to be 60.0 g/mol. What is the molecular formula? 11. Percent Yield: Calculating the percent yield helps you to know the effectiveness of your performed reaction. Assume that none of the substances were wasted during the process and no by-products are produced, then your percent yield is 100 percent, which is almost impossible to achieve.

Click the following link for more practice on limiting reagents. Android ft80.15g Mg, 0.30g Mg, 0.60g, and 1.20g Mg are all reacted with the same amount of hydrochloric acid (0.050mol HCl). For each different mass, find if the magnesium or HCl was the limiting reactant, and how much of the excess reactant was leftover, if any. Show all your work below and circle your final answer. Worksheet 10 - Balancing Reactions, Stoichiometry and Limiting Reagents 1. Write out the following reactions, and balance them. a. Sodium sulfate reacts with carbon to form sodium sulfide and carbon dioxide. b. Nitrogen dioxide reacts with water to form nitric acid and nitrogen monoxide. 2. Balance the following reactions: a. Created Date: 1/15/2016 2:59:03 PM The 0.711 g of Mg is the lesser quantity, so the associated reactant—5.00 g of Rb—is the limiting reagent. To determine how much of the other reactant is left, we have to do one more mass-mass calculation to determine what mass of MgCl 2 reacted with the 5.00 g of Rb and then subtract the amount reacted from the original amount. Finishing statement: When 20.0 grams of aluminum and 30.0 grams of chlorine are reacted according to the above equation, the chlorine is the limiting reactant and the maximum yield of aluminum chloride is 0.28 moles or 37.33 grams.
