1. (a) Reacting Pt2+ with two equivalents of each of the ligands NO2- and en, it is possible to prepare several complexes that could be described as both geometric and optical isomers of each other. Explain.
(b) What other type of isomerism might one envisage arising from the reaction given in (a)? 2. The aquated Cr2+ ion is sky blue in colour. If you were to obtain its UV-VIS spectrum, in what wavelength range will you expect this complex to absorb? Explain your reasoning. 3. (a) Determine the crystal field stabilization energy (CFSE) for the high and low spin complexes of an octahedral Co2+ metal complex. Make sure to include with your answer the energy for electron pairing as well.
(b) Identify which spin state is preferred based solely on the CFSE's. (c) Explain why though there is a preference for one over the other both cases are still possible.
Explain the Electrode reactions and the cell reaction? A cell diagram, with its designation of the left and right electrodes, allows us to write reaction equations for the cell
A diluted polymer solution with a density of 1130 kg/m3 was extruded by a capillary tube of 3.5 mm internal diameter and 1 m long. The following results were contained at 25°C.
1. A laboratory animal exercised on a treadmill that was connected to a weight with a mass of 250. g through a pulley. The work done by the animal raised the weight through 1.32 m.
