Discussion: In the first part of the experiment‚ chronoamperometry was used to determine the diffusion coefficient of ferricyanide. The chronoamperogram can be seen in Graph 1. The chronoamperogram shows three distinct regions. [1A] Region “a” is where the electrode potential is higher than the ferricyanide’s potential‚ so no reduction reaction takes place. Region “b” is where the potential is decreased to a potential much lower than that of ferricyanide. This results in the ferricyanide consuming

VI. Results and Discussion In this exercise‚ the goal was to produce acetylsalicylic acid through the organic synthesis from the reaction of salicylic acid to acetic anhydride‚ the starting materials. Instead of using acetic acid‚ acetic anhydride was used as solvent since the anhydride reacting with water to form acetic acid tends to drive the reaction to the right. It results from the elimination of a molecule of water from two molecules of acetic acid (see Fig. 11.2). Figure 11.3 below

three carbonyl’s serving as the “legs” of the stool and the mesitylene is the “seat” of the stool and is position on one face of the octahedral. This form of coordination is relatively common with olefins and metal atoms‚ the most famous being ferrocene‚ (cyclopentadiene)2Fe. It is composed of two 5-membered rings situated directly above and below the metal center. It looks like an iron sandwich. The reaction of molybdenum hexacarbonyl and mesitylene is unstable with respect to air. Because

Euthanasia: The Debate of Legalization Euthanasia is derived from the Greek word that ultimately means “good death”(Ahmed‚ 2012). The dispute surrounding euthanasia has been an on going argument for many decades. Society has always indicated mixed feelings regarding this controversial subject. The government allows humanity to euthanize animals‚ especially the terminally ill. A human’s life should be looked at in the same context‚ because no one should be left to live in pain or suffering.
