  • Positive And Negative Conduct Electricity
    595 words
    Electrolytes are liquids that conduct electricity. Most need to be dissolved into water or another solvent. Battery's have an electrolyte in them, either as a liquid or as a paste. Liquid electrolytes are used in electrolysis, electroplating, and other chemical processes. When electrolytes dissolve they release positive and negative ions. The released ions carry electric charges between electrodes, in the solution. Cations (a positively charged ion that migrates to the cathode, a negative electr...

  • Acetic Acid H 3
    842 words
    In the simple formalism proposed independently by Bronsted and Lowry in 1923, an acid was defined as a proton donor and a base was defined as a proton acceptor. In the simple acid-base reaction shown below, H 3 O+ is termed a Bronsted Acid, and HO- a Bronsted Base. In writing organic reaction mechanisms, the flow of electrons is often shown using "curved arrows" and in the example shown, the arrows are designed to show that an unshared pair of electrons from hydroxide anion moves to abstract a p...

  • Johannes Van Der Waals

    ... slightly negative and the other end of it is slightly positive. The Dispersion forces exist between non-polar molecules. Dispersion forces are another of van der Waals' three forces. They exist between non-polar molecules. It is important to remember that within a bond, electrons are constantly MOVING. They zoom around the atoms really quickly. As a result, there may be a tiny instant in that time span where the electrons happen to dominant on one side, rather than the other. However, this t...

  • Nitric Acid Scientific American
    825 words
    Chemistry Connections of nitrogen - saltpeter, nitric acid, ammonia - were known long before invention of nitrogen in a free condition. In 1772 D. Rutherford, burning phosphorus and other substances in a glass bell, has shown that the gas remaining after combustion does not support breath and burning. He named it suffocating air. In 1787 A. Lavoisier has established, that the "vital" and "suffocating" gases included in air, are simple substances, and has offered the name "nitrogen." In 1784 G. C...

  • Electron To Form Covalent Bond Bonds
    446 words
    Chemical bonds are what make up the world. In bonds, elements are held together and form compounds that may have new physical and chemical properties. There are two main kinds of bonds, they ionic and covalent. In bonding the goal of the atoms involved is to reach a level of stability with less energy. In order to reach the epitome of stability, as in the case of noble gases, an atom strives to complete its outer shell. Either losing or gaining electrons may do this, which concludes in an ionic ...

    What properties of water make it a unique material and an essential component of living matter? Water is so common that it is easy to overlook the fact that it is an exceptional substance with many amazing qualities. With its properties, we can trace water s unique behavior to the structure and interactions of its molecules. Water is constructed of two hydrogen (H) and one oxygen (O). The hydrogen become + charged and the oxygen maintains a charge when they combine to form water. This is a singl...
