Document Summary
Chapter 4 lecture notes: chemical quantities and aqueous solutions. What mass of hcl, in grams, can be neutralized by a dose of milk of magnesia containing 3. 26 g mg(oh)2? (4) What"s the theoretical yield? (5: question: ammonia, nh3, can be synthesized by reacting nitrogen monoxide with hydrogen gas. Starting with 86. 3 g of nitrogen monoxide and 25. 6 g of hydrogen gas, find the theoretical yield of ammonia in grams. (6: question: titanium metal can be obtained from its oxide according to the following balanced equation: When 28. 6 kg of c reacts with 88. 2 kg of tio2, 42. 8 kg of ti is produced. Find the limiting reactant, theoretical yield in kg and percent yield. (8: question: mining companies use the following reaction to obtain iron from iron ore. The reaction of 167 g of fe2o3 with 85. 8 g of co produces 72. 3 g fe. Find the limiting reactant, theoretical yield, percent yield and amount of excess reactant. (7)
