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

Chapter 1Mahogany Seed as a Termiticide to Kill Termites INTRODUCTION Mahogany used in multistory systems in the Philippines‚ boat and ship building and patternmaking. Logs are used for the manufacture of veneers and for paneling. It is also used as shade for coffee and cacao. Mahogany is regarded as the worlds finest timber for high-class furniture and cabinetwork. Its popularity is especially due to its attractive appearance in combination with ease of working‚excellent finishing qualities and

Hurley Abstract Preparation of nitrito-kO-complex was prepared by ligand substitution from a chloridio-complex chemically made. The nitro-kN-complex was then prepared by isomerisation of the nitrito-kO-complex. Visible absorption and infrared spectroscopy was then carried out on all three complexes. The molar absorption coefficients calculated were 38.0 cm-1 mol-1 L for the chloridio-complex‚ 76.0 cm-1 mol-1 L for the nitrito-kO-complex and 85.4 cm-1 mol-1 L for the nitro-kN-complex these values

Determination of Trace Amount of Copper and Zinc in an Aqueous Solution by Atomic Absorbance Spectroscopy Abstract: The purpose of this experiment is to analyze a sample containing copper and zinc in trace amounts‚ where standard addition method was used and the instrument used is the atomic absorbance spectroscopy. The amount of copper obtained was 0.569 ppm ± 0.015 and for zinc we obtained 0.42 ppm ± 0.0027. Introduction: This method implies the excitation of particles in the solution sample

Since the last visit blood tests were obtained‚ and an MRI with repeat MR spectroscopy. Also‚ consultation with ophthalmology revealed normal hyperopia for age. Mother continues to express concern for the child’s violent behavior but notes that overall she is doing well in school. She has some difficulties with the arithmetic
