Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

Lab Two; Chromatography of Food Dyes Jan Konig 28.04.2013 11:00am Chemistry 121‚ section DE Abstract: The second lab deals with the chromatography of food dyes which means you figure out what kind of compounds are used in a product like food color etc. by comparing the result to FD&C Food Dyes. You use six different food dyes‚ four food colors out of the store‚ two different Kool Aid powder and four different colors of candy like M&Ms you use for the chromatograph. At the end you try

DNA model of the structure resembled a twisted rope ladder. They proposed that the DNA molecule consisted of two spirally wound‚ helical chains. Rosalind Franklin (1920–1958) Franklin had established herself as a world expert in the structure of graphite and other carbon compounds. Rosalind Franklin had discovered that DNA could crystallize into two different forms‚ an A form and a B form. John Randall (was a physicist who led the King’s College London team which worked on the structure of DNA) gave

CHAPTER 4 AIRCRAFT BASIC CONSTRUCTION INTRODUCTION Naval aircraft are built to meet certain specified requirements. These requirements must be selected so they can be built into one aircraft. It is not possible for one aircraft to possess all characteristics; just as it isn’t possible for an aircraft to have the comfort of a passenger transport and the maneuverability of a fighter. The type and class of the aircraft determine how strong it must be built. A Navy fighter must be fast‚ maneuverable

Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat

524 SILICON CARBIDE Vol. 22 SILICON CARBIDE 1. Introduction Silicon carbide [409-21-2] (SiC) is a technologically important material that is one of the small number of unusual materials that were first created synthetically and then subsequently discovered in nature. Silicon carbide was first observed in its natural form in 1905 by the Nobel-prize-winning chemist Henri Moissan‚ who discovered it in the meteor that created the Diablo Canyon in Arizona. The transparent mineral‚ now known as
