1. Why the ribozyme interacts with one of the two non bridging phosphate oxygen atoms at the cleavage site, but not via inner sphere coordination with a divalent metal ion at the active site? 2. Why pistol ribozymes do not require inner sphere coordination of divalent metal ions anywhere in the structure, including at the active site? 3. Why the pistol ribozyme contract with one of the two non bridging oxygen atoms in a way that is strongly disrupted by...
ionic compounds Are ionic structures (comprised of a metal and a non-metal) always completely ionic? Why or why not? defects Describe at least on defect type in a 3D crystal. What effect does this have on the material's properties?
why are metallic elements which form ionic oxides basic and why are non-metal oxides which are covalent acidic?
Explain the process of formation for solutions that are produced by dissolving ionic and molecular compounds (e.g., salt, oxygen) in water, and for solutions that are produced by dissolving non-polar solutes in non-polar solvents (e.g., grease in vegetable oil)
Why are many ionic compounds not soluble in water? A. They are non-polar and do not mix well with H2O B. They have metals that are much denser than water C. They have high charge density which makes stronger ionic bonds that water can’t break D. They have weak ionic bonds that cause them to precipitate E. The higher pressure of water causes solids to precipitate

would CO2 be classified as ionic or covalent? explain why
2. Explain why the citric acid cycle only operates in the presence of oxygen yet it is not a substrate in any of the reactions in the sequence.
Explain why patients exhibiting cystic fibrosis should have different NPD levels than patients not exhibiting cystic fibrosis.
Using the following ionic radii, explain why Ca(NO3)2 is soluble, but CaSO4 is not. Ca2+ = 1.14 Ǻ, NO3– = 1.65 Ǻ, SO42- = 2.44 Ǻ. (Ca(NO3)2 = rutile structure, CaSO4 = sodium chloride structure)
