    experiences I have ever had was signing up for Advance Chemistry in the 11th grade and the subsequent three that I scored on the Advance Placement exam at A.R. Johnson in the school year of 2013-2014. This class was the first Advance Placement class I took after coming off a strong 10th grade chemistry finish. That means I got a high B in the class which or the that reason, my teacher Dr. Grayson strongly persuaded me to go into her Advanced Placement Chemistry course. As a matter of fact, I have always

    Dangerous goods are indicated by diamond figure (Patnaik, 2002). The colour of the diamond indicates the nature and extent of the hazard associated with the material. The codes and notations assigned to hazardous materials are adopted from the guidelines of National Fire Protection Agency (NFPA) (Mondanaro &Dailey, 2004). In the present case it is observed that there is a placard bearing 'Dangerous when wet' with a class 4 label code and a UN1836 on orange panel. Figure1. Class 4.3-Combustible

    CHAPTER 2 EXPERIMENTAL TECHNIQUES FOR THE SYNTHESIS AND CHARACTERIZATION OF NANOMATERIALS. In order to explore novel physical properties and phenomena and realize potential applications of nanostructures and nanomaterials, the ability to fabricate and process nanomaterials and nanostructures is the first corner stone in nanotechnology. There exist a number of methods to synthesize the nanomaterials, which are categorized in two techniques “top down and bottom up”. Solid state route, ball milling

    Introduction Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation, which involves mixing an alkyl or acyl halide with a Lewis acid, or acylation, which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation, second electrophilic attacks

    Additionally, once the zeolite molecular sieve columns are saturated with radium, the resulting solid radioactive waste must be disposed of because the radium binds too tightly to the zeolite and cannot be removed for future use in energy or heat production. Thus, this method still produces radioactive waste, which has reached a total of one million tons in just one year.17 Because the solid waste produced exceeds radioactive material soil application and landfill limits, this waste must be disposed

    The primordial soup hypothesis is a hypothesis that was identified by a Russian chemist named Oparin and an English genetics, Haldin in the year 1920. The hypothesis explains that life began in a pond or an ocean from a combination of chemicals from the atmosphere. The two scientists thought that that the basic building blocks of life came from a simple molecule that was formed in the atmosphere. Evidence that they used to create this hypothesis was that they observed a molecule that was energized

    Megan Entwistle, Maria Amos, and Paul Golubic CHEM 0330 Organic Lab 1 Sodium Borohydride Reduction: Diphenylmethanol from Benzophenone 11/16/11 Introduction Redox (shorthand for REDuction-OXidation) reactions are chemical reactions in which the oxidation state (or oxidation number) of atoms has changed. Oxidation can be observed through the loss of electrons or an increase in oxidation state by an atom, ion or molecule. Reduction describes the gain of electrons or decrease in oxidation state
