We know that sc has an electron configuration of 3d'4s2 and cr has an electron configuration of 3d 4s1. using hartree-fock theory what is the difference in energy between sc in the electron configuration of 3d 4s2 and 3d 4s'? what is the energy difference between cr in the electron configuration of 3d54s1 and 3d44s"? if we assume that the coulomb integrals are the same: / = jm3d = 14s4s-iadss and the exchange integrals are the same: k kjasdk4sskas what do these energy differences simplify to? what does this tell us about the difference between the 3d and 4s orbitals (ε3d-e4s) in relation to the exchange integral k? note that for this problem ignore all the other electrons except the ones in the 4s and 3d orbitals.

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
