Problem 49P

Consider the combustion of one mole of H2 with 1/2 mole of O2 under standard conditions, as discussed in the text. How much of the heat energy produced comes from a decrease in the internal energy of the system, and how much comes from work done by the collapsing atmosphere? (Treat the volume of the liquid water as negligible.)

Step-by-Step Solution:

CHEM 1030 EXAM 3 STUDY GUIDE Molecular Geometry A. Molecular shape can be predicted by using the valence-shell electron-pair repulsion (VSEPR) model (AB ) X B. A is the central atom surrounded by X B atoms C. X can have integer values of 2 to 6 D. The basis of the VSEPR model is that electrons repel each other E. Electrons are found in various domains, either in lone pairs, single bonds, double bonds, or triple bonds F. Electrons will arrange themselves to be as far apart as possible, so as to minimize repulsion interactions G. The electron domain geometry is the arrangement of electron domains around the central atom —> 2 electron domains is linear —> 3 electron domains is trigonal planar —> 4 electron domains is tetrahedral —> 5 election domains is trigonal bipyramidal —> 6 electron domains is octahedral H. The molecular geometry is the arrangement of bonded atoms I. In an ABXmolecule, a bond angle is the angle between two adjacent A-B bonds J. AB Xolecules contain two different bond angles between adjacent bonds 1. Axial positions are perpendicular to the original plane 2. Equatorial positions are the bonds on the same plane K. When the central atom in a AB X molecule bears one of more lone pairs, the electron- domain geometry and the molecular geometry are no longer the same The steps to determine the electron-domain and molecular geometrics are as follows: Step 1: Draw the lewis structure
