A possible geometry for an eight-coordinate complex ML8 might be a hexagonal bipyramid: a. Predict the effect of the eight ligands on the energies of the d orbitals of a metal M, using ligand field theory and assuming that the ligands are sigma donors only. b. For this geometry, and assuming low spin, which dn configurations would be expected to give rise to Jahn-Teller distortions

How do dying stars contribute to the formation of planets

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

Describe the process that was used in this lab to create magnesium oxide, specifically identifying the type of chemical reaction. explain why the product had a higher mass than the reactant, and how this relates to conservation of matter.
