Sketch a qualitative MO diagram for [Ni(NH3)6]2+ and identify the portion of the diagram considered by crystal-field theory. Imagine the ammonia ligands were all exchanged with a ?-donor ligand. Show how the MO diagram would be impacted. How does this help explain the placement of ligands in the spectrochemical series?
Draw a flow chart that illustrates how you would purify an organic compound that is contaminated with inorganic solids that are water soluble
A gas cylinder at a pressure of 5.80 atm contains both helium and oxygen. The helium is at a pressure of 2.35 atm. What is partial pressure of oxygen?
If a sample of pure silver (Ag) contains 3.35 x 1022 atoms of iodine, how many moles of silver are in the sample?
A sample of 0.50 moles of O2 gas initially at 250K and a pressure of 1.0 atm is compressed to final pressure of 12 atm. The compression can occur via two different paths
CaCO3 (100.1 g/mol) has a solubility of 0.018 g/100 mL in water at 35?C. What is the value of Ksp at this temperature?
