Department of Chemistry - The University of Western Ontario Chem024b - 2008 - TUTORIAL 1 Topics covered: lecture chapter 1 ( Fundamentals, Stoichiometry ) lecture chapter 2 ( Reactions in Aqueous Solution ) MH5, Problem 1.49 (252.5 g) MH5, Chapter 2: Summary Problem (a) - (h) [p. 47] MH5, Problems 2.14, 2.16, 3.6, 3.14, 3.18, 3.26, 3.30, 3.46 MH5, Problem 3.34; also determine the empirical formula of the compound (C 13 H 6 Cl 6 O 2 ). Combustion of 1.750 g of a compound in excess oxygen yields 1.695 g H 2 O and 4.142 g CO 2 . What is the simplest formula of this compound? A) C 7 H 14 O 2 B) C 7 H 7 O 4 C) C 8 H 10 O 3 D) C 8 H 16 O E) C 9 H 6 O MH5, Problems 3.58, 3.62, 3.64, 3.66 MH5, Problem 3.68 Hint: Use the balanced reaction 3 Al(s) + 3 NH 4 ClO 4 (s) Al 2 O 3 (s) + AlCl 3 (s) + 3 NO(g) + 6 H 2 O(g) 8.15 g C 2 H 4 (g) react with excess oxygen according to the (unbalanced) equation
