Unformatted text preview: Review of Bonding/Molecular Geometry (Chapters 8 and 9) Circle the compounds that are likely to have a dipole moment, i.e. those that are polar molecules. HF H 2 O CO CO 2 BF 3 NH 3 CH 4 CH 3 OH C 6 H 6 Do not memorize – work through these using Lewis structures and number of electron domains (Tables 8.1,9.2 and 9.3) Intermolecular Forces Which molecule in each pair has stronger intermolecular forces? H 2 or CH 4 CH 3 OCH 3 or CH 3 CN CH 3 CHO or CH 3 OCH 3 Phase Changes Calculate the heat (kJ) required to convert 50.0 g H 2 O at -5.00 o C to steam at 115 o C. specific heat ice 2.09 J/g o K specific heat water 4.18 J/g o K 15.2 kJ specific heat steam 1.84 J/g o K ∆ H fus (ice) 334 J/g ∆ H vap (liquid water) 2260 J/g -5.00 o C to 0 o C 50.0 g X 2.09 J/g o C X (0.00 o C-[-5.00 o C]) = 522.5 J at 0 o C 50.0 g X 334 J/g = 16,700 J o C to 100 o C 50.0 g X 4.18 J/g o C X (100 o C-0.00 o C) = 20,900 J at 100 o C 50.0 g X 2.26 x 10 3 J/g = 113,000 J 100 o C to 115 o C 50.0 g X 1.84 J/g o...
