Peat Formation Peat is a partially decayed organic matter laid down in anaerobic‚ or lacking oxygen‚ conditions in wetlands. Peat forms when plant material‚ usually in marshy areas‚ is inhibited from decaying fully by acidic conditions. It is composed mainly of peat moss or sphagnum‚ but also includes trees‚ grasses‚ and other marshland vegetation. It also includes many other types of organic remains such as fungi‚ insects‚ pollen‚ and on occasion dead animals. Peat formed in very wet conditions

The objective of this lab was to prepare n-butyl bromide or n-bromobutane‚ which is derived from an alcohol and an acid. In this case‚ n-butyl alcohol and sulfuric acid were the reagents. There were two methods of distillation that was involved in this experiment. The first was by reflux distillation‚ which is used to speed up a chemical reaction without having the reactants/ products evaporate or explode. Data Table 1 indicates the amount of each reagents that was prepared for the reflux apparatus

Biofilm formations have a specific arrangement that include attachment and development. At each step‚ the biofilm becomes more strongly attached and the bacteria within it become more protected from the action of antibiotics and the immune responses. The steps of biofilm formation; Step 1: attachment Within seconds‚ bacteria get

Synthesis of Isopentyl Acetate Abstract Isopentyl acetate was synthesized via a Fischer Esterification and purified via simple distillation. The yield was determined to be 25%. The identity and purity of the product was confirmed by comparison of the measured ultra-micro boiling point (140°C) to the published value (142°C).1 Chemical Equation Procedure Isopentyl alcohol (0.787 g‚ 1.2 mL‚ 8.93 mmol)‚ acetic acid (1.574 g‚ 1.5 mL‚ 26.20 mmol)‚ and sulfuric acid (0.368

Abstract Isopentyl acetate was synthesized in 44.9% yield through a reaction between isopentyl alcohol and acetic acid‚ with sulfuric acid as a catalyst. Identify and purity of the product was confirmed by infrared spectrum analysis of the product and the boiling point (141-142˚C) to the published value of (lit1142.5 ˚C). Procedure: Isopentyl alcohol (.893g)‚ acetic acid (2ml)‚ and concentrated sulfuric acid (4 drops) was added to a 5ml conical vial‚ and then attached to a reflux apparatus.
