(Gauss' law 3) The Gaussian surface is a sphere with a radius of 10 cm. At the center of the sphere is a point charge. At the Gaussian surface (10 cm from the point charge) an electric field of 5000 N/C is directed away from the point charge. a) Draw the Gaussian surface around the point charge. Show electric field...

1b Assume two octahedral coordination compounds, each containing the same central metal ion with five unpaired d electrons (e g. Fe3+) One compound contains a weak-field ligand (e.g. F) and the other compound contains a strong-field ligand (e g CN). Compared to the strong-field compound, it is expected that the weak-field compound would have a I. smaller magnetic moment and...
