    Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature, some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However, the excited configuration is unstable, and the electrons must return back to their positions in the lower energy level. As they return, the energy that was previously absorbed is now emitted...

    procedures were divided into two categories. First the formation of phenylmagnesium bromide, and second the reaction of the phenylmagnesium bromide with the carbonyl compound. However, before any of this could be done, the refluxing apparatus for the Grignard reaction was to be flame dried until no moisture remained inside because any water would cause the reagent to decompose and an alkane to form. The reaction would subsequently fail. Drierite was placed inside a plastic drying tube as a drying agent...

    Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life, the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece, 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles, it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman, 2008). Diffusion...
