Biochem Module 2 Questions and Answers Graded A What is the shape of water? Bent. The bond angle is 104.5 degrees. What is autoionization, and how is it important for water? Autoionization is the ability of a compound to react with itself to form ions. One water molecule reacts with a second molecule to form two ions: H3O+ and OH-. These ions exist in small amounts in pure water and influence the chemistry of water. Name the three non-covalent forces discussed in this module 1. Dipole-dipole f...

In the chromatography of the reaction mixture, water absorbed on cellulose functioned as the stationary phase. What was the principal factor determining the migration of individual components in the sample? A.Hydrogen bonding B.Solute concentration C.Stationary phase concentration D.Thickness of paper B and D are dumb options. Knock them out. hydrogen bonding to the stationary phase will determine the relative rate of migration of the various components in the sample. When thinking ...
