Also “stable lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation‚ hydrogenation‚ and polymerization applications.” In other words it can be used as a catalyst in splitting molecules in refineries‚ it can be used to produce a chemical reaction between hydrogen and another compound or element‚

Acetylation of Ferrocene 17. October 1996 Experiment #7 Introduction In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings. In order to determine how well this process had worked we employed: IR spectra analysis‚ column chromatography‚

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.
