You add an excess of solid MX in 250 g of water. You measure the freezing point and find it to be _ What is the Ksp of the solid? Assume the density of the solution is 1.0 g/cm3.
General Chemistry 115 Week 6 Electron Geometry VSEPR; describes shape of electron pairs Describes both lone pairs AND bonds around central atom Molecular Geometry Describes arrangement of nuclei Includes geometry of ONLY bonds Bond Angles and Lone Pair Geometry: Lone pairs take up more space than bonds Distortion in bond angle is a result because the lone pair electrons are larger and repel the electrons in the bonds. The bonds can approach closer because bonds are smaller than nonbonding electrons e.g. Methane (CH4) = 109.5 degrees bond angle Ammonia (NH3) = 107.5 degrees bond angle (one lone pair present) Water (H2O) = 104.5 degrees (2 lone pairs present) Imagine molecular geometry as a s
