Quantities with Chemical Reactions Worksheet Name Date Write the balanced equation described in each problem and then solve the problem 1. Consider the following Reaction. CH, 6) +02.01, CO2 (s) + H20 A chemist allows 23.2g of CH, and 78.3g 0, to react. When the reaction is finished, the chemist collects 52.7g CO2. Determine the limiting reagent, theoretical yield, and percent yield for the reaction. (Hint: first step balance the Chemical Reaction] 2. Consider the following Reaction. Mg(OH)2 (ap + H,PO. Mg,(PO)2 (+ HO. A chemist allows 30.6g of Mg(OH), and 63.6g H,PO, to react. When the reaction is finished, the chemist collects 34.7g Mg:(PO4)2. Determine the limiting reagent, theoretical yield, and percent yield for the reaction. [Hint: first step balance the Chemical Reaction]
