In transition metal complexes, the central metal ion is surrounded by ligands. According to Crystal field Theory, the interaction between the ligands and the metal ion, cause an increase in the energy of the d-orbitals, increasing the energy of some of the d-orbital more than others. Thus, for the metal ion in these complexes the five d-orbitals are not degenerate, a splitting of the energy levels is observed. This in turn is responsible for the absorption spectrum of various complexes in the visible region of the electromagnetic spectrum. Which of the following has the least effect on the magnitude of this energy splitting? A) Molecular Geometry of the compound
B) The oxidation state of the metal ion
C) Nature of the ligands surrounding the metal ion
D) Nature of the metal atom
E) Temperature
F) The coordination number of the metal

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.

Explanation for basic character?

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
