Kierra Roberts 1-4-11 11B How Do Batteries Work? Electricity is the flow of electrons through a wire‚ that is called a circuit. Batteries have three parts to them‚ an anode‚ a cathode‚ and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the

One of the alternatives is to use the electric motor instead of gasoline one. An electric car is a car that powered by an electric motor rather than a regular gasoline engine. There are several major differences between gasoline and electric cars. First of all‚ “the electric motor will replace the gasoline engine” (“How Electric”‚ 2004). Secondly‚ “the electric motor is powered by a controller” (“How Electric”‚ 2004). Thirdly‚ “the controller gets power from the rechargeable batteries” (“How

CORROSION Corrosion is defined as the involuntary destruction of substances such as metals and mineral building material by surrounding media‚ which are usually liquid (i.e. corrosive agents)." Most metals corrode. During corrosion‚ they change into metallic ions. In some cases‚ the product of corrosion itself forms a protective coating. "For example‚ aluminium forms a thin protective oxide layer which is impervious to air and water. In other cases (e.g. iron)‚ however‚ the coating either flakes

Electrodeposition Coating Process for Automobile Bodies* By Yoshiaki 0YABU‚** Nobuo FURUNO‚*** Yoji HIRASAWA*** and Hiroshi OMORI **** Synopsis The earlier electrodeposition processwas mainlypursuitedfor the quality control in terms of mass production. However‚ the coating efficiency was picked up to be a serial problemfrom a standpoint of the harmony between natural circumstancesand human’s living-life conditions and the recovery usage of the paint was earnestlysearched. This trend

Stage 2 Chemistry Investigation Folio: Practical – Galvanic Cell Name: YY Names of Partner: ZZ Part A Investigation Design Proposal: Purpose of Experiment: To determine the effect of concentration of reactants on the current produced by a galvanic cell. Hypothesis: The greater the concentration of solution in the two half cells reacting with the two metals to produce current‚ the greater the flow of current will be produced from the galvanic cell. Independent Variable: Concentration

Osmolality and electrolytes in cerebrospinal fluid and serum of febrile children with and without seizures. During acute febrile diseases mild disturbances of water and electrolyte balance occur frequently. It has been suggested that changes in electrolyte balance‚ in particular hyponatraemia‚ might predispose a child to convulsions during febrile illness; however‚ the changes of electrolytes in the CSF are not known. We have studied the effects of fever and convulsions on water and electrolyte

ISE Determination of Fluoride Content in Various Substances CHM 222 – A 4 / 20 / 2007 Introduction: The ion selective electrode used was made up of a silver / silver chloride reference electrode and a glass electrode. The pH of the electrochemical cell is determined by monitoring the electrical potential difference between the half-cells. The glass electrode is an ion selective electrode (ISE)‚ which only responds to the hydronium ion concentration / activity in a solution under a

Investigating in the effect of ion concentration in electrolytes on the potential difference in a voltaic cell Introduction When two electrodes made of different metals are connected together in a voltaic cell‚ the chemical energy present is converted into electrical energy and an electromotive force is generated. This force‚ called the electrode potential‚ is normally measured under standard conditions‚ which is 298K‚ 1 mol dm-3 solution for the electrolyte. However when one measures the electrode
