Unformatted text preview: 2 O(l) How many grams of the excess reagent remains? Limiting Reagents Chp. 4.3 Percent Yield = x 100 Actual Yield Theoretical Yield Theoretical Yield – maximum obtainable yield. Actual Yield – the amount of product otained from a reaction. Percent Yield Chp. 4.4 TiCl 4 (g) + 2Mg(l) → Ti(s) + 2MgCl 2 (900 -1100 o C) If 3.54 x 10 7 g of TiCl 4 are reacted with 1.13 x 10 7 g of Mg, 8.93 x 10 6 g of Ti should theoretically be formed. What is the percent yield if 7.91 x 10 6 g of Ti are formed? Percent Yield Chp. 4.4 Solution Stochiometry Chp. 4.5 How many grams of Ca(OH) 2 are needed to neutralize 25.0 mL of .100 M HNO 3 ? Ca(OH) 2 + 2HNO 3 → 2H 2 O + Ca(NO 3 ) 2 Solution Stochiometry Chp. 4.5...
