  • Language Of Chemistry

    1003 words, 5 pages

    Chemistry has it’s own language, wich you should undersand if you want to study chemistry. Chemistry has a lot of symbols and formulas that you have to learn to understand the language of chemistry. Before you can begin to name compounds you must first learn the names of almost all elements or learn the most common elements. The language seems to be complicated all the formulas and symbols but if you are entusiastic about it it can be easy to learn. There are more reasons why scientists use the language of symbols and formulas. But one of the main reasons is that it

    Radical Chlorination Of Chlorobutane

    1003 words, 5 pages

    Introduction: The radical chlorination of chlorobutane results in the formation of four possible products. These products are formed by substitution reactions, where a halogen atom (chlorine) replaces a hydrogen atom (Wade 2010). The amount of each product formed is based on the relative reactivity of the product. The calculations of the relative reactivity are dependent on the reactivity of the hydrogen atoms, which is influenced by the chloro substituent as well as other factors such as the level of the substituted carbon and the bond dissociation energy. For this l

    Neuro Linguistic Programming Evident In Conversation

    1009 words, 5 pages

    The first conversation I witnessed took place in an airport between what seemed to be two married couples standing in the queue for the flight check in. I concentrated on the two women as opposed to the two men for the simple reason they seemed to be communicating (verbally) more than the men and I felt I could gain more material from them. The first thing I noticed was their rapport. I did not need to know what their topic was to understand they were both on the same wavelength and in complete agreement with each other. Their bodily stances were both very open and non

    MODULE C4: CHEMICAL PATTERNS C4.1 What are the patterns in the properties of elements? 1. recall that atoms of each element have different proton numbers; 2. understand that arranging the elements in order of their proton numbers gives repeating patterns in the properties of elements; 3. be able to use the Periodic Table to obtain the names, symbols, relative atomic masses and proton numbers of elements; 4. recall that a group of elements is a vertical column in the Periodic Table and that the elements have similar properties; 5. recall that a period is a row of e

    High-performance liquid chromatography (formerly referred to as high-pressure liquid chromatography), HPLC, is a chromatographic technique used to separate the components in a mixture, to identify each component, and to quantify each component. HPLC is considered an instrumental technique of analytical chemistry (as opposed to a gravimetric technique). In general, the method involves a liquid sample being passed over a solid adsorbent material packed into a column using a flow of liquid solvent. Each analyte in the sample interacts slightly differently with the adsorben

    What Is Chemistry

    1268 words, 6 pages

    At one time it was easy to define chemistry. The traditional definition goes something like this: Chemistry is the study of the nature, properties, and composition of matter, and how these undergo changes. That served as a perfectly adequate definition as late as the 1930s, when natural science (the systematic knowledge of nature) seemed quite clearly divisible into the physical and biological sciences, with the former being comprised of physics, chemistry, geology and astronomy and the latter consisting of botany and zoology. This classification is still used, but the emergence of important i

    Organic Qualitative And Quantitative Analysis

    1452 words, 6 pages

    The main objective of this experiment was to identify the functional group of an unknown compound through a series of qualitative testing and determine its molecular mass via the Dumas method. This method is based off the vapour produced by the unknown and a measurement of the volatized solid can be made for the determination of the mass. The four main functional groups that were tested include: aldehydes, ketones, alcohols, and esters.1 Each group will be tested with a different reagent or method, that will solidify its identification and a control test will be run for qualitative comparis
