have been precipitated by microbes which include carbonates‚ sulphates‚ silicates etc [1]. Amongst all these‚ carbonates are the most common minerals formed. Carbonate precipitation has been applied in several fields ranging from removal of heavy metals and radio nucleotides‚ waste water treatment‚ biodegradation of pollutants‚ CO2 sequestration and filler in rubber and plastics and greatly in remediation and restoration

element in the periodic table‚ it is in period 4‚ group 16 which is also called the chalcogen group. The term chalcogen stands for “sulfur”‚ therefore all elements in family 16 are similar to the element sulfur. All the elements in family 16 are non-metals and all of these elements in chalcogen family have six electrons in the outermost shell so they all have the similar properties. Give a description of the physical characteristics and chemical properties of the element. Physical characteristics:

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‚
