  • A Complete Guide to Benzene
    A Complete Guide to Benzene Benzene is an important organic chemical compound with the chemical formula C6H6. The benzene molecule is composed of six carbon atoms joined in a ring with one hydrogen atom attached to each. As it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals. Due to the cyclic continuous pi bond between the carbon atoms, benzene is classed as an aromatic hydrocarbon, the second [n]- annulene ([6]-annulene). It is sometimes abbreviated Ph–H. Benzene is a colourless and highly flammable liquid with a sweet smell. Source: Wikipedia Protecting people and the environment Protecting both people and the environment whilst meeting the operational needs of your business is very important and, if you have operations in the UK you will be well aware of the requirements of the CoSHH Regulations1 and likewise the Code of Federal Regulations (CFR) in the US2. Similar legislation exists worldwide, the common theme being an onus on hazard identification, risk assessment and the provision of appropriate control measures (bearing in mind the hierarchy of controls) as well as health surveillance in most cases. And whilst toxic gasses such as hydrogen sulphide and carbon monoxide are a major concern because they pose an immediate (acute) danger to life, long term exposure to relatively low level concentrations of other gasses or vapours such as volatile organic compounds (VOC) are of equal importance because of the chronic illnesses that can result from that ongoing exposure. Benzene, a common VOC Organic means the chemistry of carbon based compounds, which are substances that results from a combination of two or more different chemical elements.

  • All About the Chemical Bonds and Compounds
    All about the Chemical Bonds and Compounds Video Transcript Almost everything we see or touch in daily life – such as the food we eat, the water we drink, the air we breathe, and so on – is the result of chemical bonding. In other words, the world around us is generally not composed of isolated atoms. Instead, atoms bond to one another to form molecules and hence chemical compounds, which make up the world around us. Chemical bonding is the physical process that causes atoms and molecules to be attracted to each other and held together in more stable chemical compounds. There are three primary types of chemical bonds and compounds: Ionic bonds, covalent bonds, and metallic bonds. With ionic bonds, electrons are exchanged or transferred between atoms. They exist in ionic compounds. Generally, they’re a metal and a nonmetal – sodium chloride, magnesium oxide, etc. With covalent bonds, electrons are shared among the atoms. They exist in covalent and molecular compounds. Generally, they are nonmetals – carbon dioxide, dihydrogen monoxide, etc. With metallic bonds, a pool of electrons roam freely across entire molecule. They exist in metallic compounds. Generally, they’re metals and alloys – copper, gold, etc. A chemical compound is a group of two or more different atoms that are attracted to each other. Compounds can be divided into ionic compounds, covalent compounds, and metallic compounds. This table lists some key properties of each. Be aware that it is the valence electrons (those in the outermost level) that are involved in bonding. Atoms try to fill their outer energy levels because it’s energetically favorable for atoms to be in that configuration and it makes them stable.

  • Chapter 10 – Chemical Reactions Notes
    Chapter 8 – Chemical Reactions Notes Chemical Reactions: Chemical reactions are processes in which the atoms of one or more substances are rearranged to form different chemical compounds. How to tell if a chemical reaction has occurred (recap): Temperature changes that can’t be accounted for. o Exothermic reactions give off energy (as in fire). o Endothermic reactions absorb energy (as in a cold pack). Spontaneous color change. o This happens when things rust, when they rot, and when they burn. Appearance of a solid when two liquids are mixed. o This solid is called a precipitate. Formation of a gas / bubbling, as when vinegar and baking soda are mixed. Overall, the most important thing to remember is that a chemical reaction produces a whole new chemical compound. Just changing the way that something looks (breaking, melting, dissolving, etc) isn’t enough to qualify something as a chemical reaction! Balancing Equations Notes: Things to keep in mind when looking at the recipes for chemical reactions: 1) The stuff before the arrow is referred to as the “reactants” or “reagents”, and the stuff after the arrow is called the “products.” 2) The number of atoms of each element is the same on both sides of the arrow. Even though there may be different numbers of molecules, the number of atoms of each element needs to remain the same to obey the law of conservation of mass. 3) The numbers in front of the formulas tell you how many molecules or moles of each chemical are involved in the reaction. 4) Equations are nothing more than chemical recipes.

  • 1 5. Chemical Bonding
    5. Chemical Bonding: The Covalent Bond Model 5.1 The Covalent Bond Model Almost all chemical substances are found as aggregates of atoms in the form of molecules and ions produced through the reactions of various atoms of elements except the noble-gas elements which are stable mono-atomic gases. Chemical bond is a term that describes the attractive force that is holding the atoms of the same or different kind of atoms in forming a molecule or ionic solid that has more stability than the individual atoms. Depending on the kinds of atoms participating in the interaction there seem to be three types of bonding: Gaining or Losing Electrons: Ionic bonding: Formed between many ions formed by metal and nonmetallic elements. Sharing Electrons: Covalent bonding: sharing of electrons between two atoms of non-metals. Metallic Bonding: sharing of electrons between many atoms of metals. Ionic Compounds Covalent Compounds Metallic Compounds 1.

    Key Ideas of Elementary Mathematics Sybilla Beckmann Department of Mathematics University of Georgia Lesson Study Conference, May 2007 Sybilla Beckmann (University of Georgia) Key Ideas of Elementary Mathematics 1/52 US curricula are unfocused A Splintered Vision, 1997 report based on the TIMSS curriculum analysis. US state math curriculum documents: “The planned coverage included so many topics that we cannot find a single, or even a few, major topics at any grade that are the focus of these curricular intentions. These official documents, individually or as a composite, are unfocused. They express policies, goals, and intended content coverage in mathematics and the sciences with little emphasis on particular, strategic topics.” Sybilla Beckmann (University of Georgia) Key Ideas of Elementary Mathematics 2/52 US instruction is unfocused From A Splintered Vision: “US eighth grade mathematics and science teachers typically teach far more topic areas than their counterparts in Germany and Japan.” “The five surveyed topic areas covered most extensively by US eighth grade mathematics teachers accounted for less than half of their year’s instructional periods. In contrast, the five most extensively covered Japanese eighth grade topic areas accounted for almost 75 percent of their year’s instructional periods.” Sybilla Beckmann (University of Georgia) Key Ideas of Elementary Mathematics 3/52 Breaking the “mile-wide-inch-deep” habit Every mathematical skill and concept has some useful application has some connection to other concepts and skills So what mathematics should we focus on?

  • TSCA Inventory Representation for Products Containing Two Or More
    mixtures.txt TOXIC SUBSTANCES CONTROL ACT INVENTORY REPRESENTATION FOR PRODUCTS CONTAINING TWO OR MORE SUBSTANCES: FORMULATED AND STATUTORY MIXTURES I. Introduction This paper explains the conventions that are applied to listings of certain mixtures for the Chemical Substance Inventory that is maintained by the U.S. Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA). This paper discusses the Inventory representation of mixtures of substances that do not react together (i.e., formulated mixtures) as well as those combinations that are formed during certain manufacturing activities and are designated as mixtures by the Agency (i.e., statutory mixtures). Complex reaction products are covered in a separate paper. The Agency's goal in developing this paper is to make it easier for the users of the Inventory to interpret Inventory listings and to understand how new mixtures would be identified for Inventory inclusion. Fundamental to the Inventory as a whole is the principle that entries on the Inventory are identified as precisely as possible for the commercial chemical substance, as reported by the submitter. Substances that are chemically indistinguishable, or even identical, may be listed differently on the Inventory, depending on the degree of knowledge that the submitters possess and report about such substances, as well as how submitters intend to represent the chemical identities to the Agency and to customers. Although these chemically indistinguishable substances are named differently on the Inventory, this is not a "nomenclature" issue, but an issue of substance representation. Submitters should be aware that their choice for substance representation plays an important role in the Agency's determination of how the substance will be listed on the Inventory.
