Problem 89

Given that the \(\Delta H_{\mathrm{f}}^{\circ}\) of \(1 \mathrm{M} \mathrm{H}_{2} \mathrm{SO}_{3}\) is -633 kJ, use the data in Appendix II, Table B to calculate the \(\Delta H^{\circ}\) for the formation of a 1 M solution of \(\mathrm{SO}_{2}\) in water from \(\mathrm{SO}_{2}(\mathrm{~g})\).

CEM 141 Lecture 32: IMFs and Structure Properties (Part 1) Dr. Jian Hu November 18 , 2016 Hydrogen Bonding  Hydrogen Bonding interactions only ocurr in very specific molecules  They occur between two molecules st  1 molecule: must contain H covalently bonded to O, N, or F  since any of the H-O, H-N, or H-F bonds are highly polarized, the H atom has a large positive dipole  2 molecules: must have O, N, or F with a lone electron pair  this lone pair will develop a large negative dipole  Hydrogen bonding interactions are extremely strong, and are a specific type of dipole- dipole interaction  Any compound that contains hydrogen bonding interactions also contains dipole-dipole interactions as well as LDFs  Strands of DNA (in double helix form) are held together by hydrogen bonding interactions  Hydrogen bonding interactions in water are responsible for the unusual properties of water; hydrogen bonding interactions also have direction  Will a sample of CH NH display hydrogen bonding interactions 3 2 First draw the Lewis Structure: Since hydrogens are covalently bonded to a nitrogen, and there is a lone electron pair on the nitrogen, hydrogen bonding interactions will form between these molecules  this could not have been determined without drawing the Lewis Structure to determine which bonds were present in the structure and whether the
