In this study, we can prove that electricity can be produced by vinegar. After all, vinegar is abundant everywhere. A battery is an electrochemical device that converts chemical energy to electrical energy. It contains thousands of charges (protons & electrons). It is also defined as a container consisting of one or more cells, in which chemical energy is converted into electricity and is used as a source of power. Likewise, vinegar is a liquid consisting mainly of acetic acid and water

known quarks with the number of known leptons, and implied a mass formula that correctly reproduced the masses of the known mesons.[26] In 1968, deep inelastic scattering experiments at the Stanford Linear Accelerator Center (SLAC) showed that the proton contained much smaller, point-like objects and was therefore not an elementary particle.[6][7][27] Physicists were reluctant to identify these objects with quarks at the time, instead calling them "partons"—a term

Chapter 3 Introduction to Microcontrollers 3.1 Just a Start Up A microcontroller (also MCU or ¥ìC) is a computer-on-a-chip. It is a type of micro-computer element that emphasizing high integration, low power consumption, self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor. In addition to the usual arithmetic and logic elements of a general purpose microprocessor, the microcontroller typically integrates additional elements such as read-write memory for

Cellular respiration is a catabolic reaction that takes place cytosol and inside of both outer and inner membranes of mitochondria. Cellular respiration consists of multiple stages that aim to break down glucose into water and carbon dioxide to generate ATP for energy use. Glycolysis in the cytosol, Krebs cycle in the mitochondrial matrix, and oxidative phosphorylation on inner mitochondrial membrane take place in a consecutive order for cellular respiration. The glucose provides as the energy source

Elements such as fluorine, chlorine, bromine, iodine, and astatine belong to the halogen group. Iodine is a chemical element of the periodic table with the symbol I and atomic number 53. Iodine has 53 protons and 53 electrons and 78 neutrons. Iodine was discovered in 1811 by the French chemist Barnard Courtois. He was extracting sodium and potassium from seaweed ashes. He accidentally added too much of sulfuric acid (H2SO4) then a violet colored cloud erupted from the mass.The gas condensed on

They become less basic when mixed with acids. In any acid-base reaction, the equilibrium favors the reaction that moves the proton to the stronger base. When an acid and base combine, they react to neutralize the properties. Acids become less acidic when mixed with bases. The neutralization reaction of an acid with base will produce water and salt. Titration is a method used

Technology Literature Review Cox, A. (2011). “The acceptability of e-technology to monitor and access patient symptoms following palliative radiotherapy for lung cancer.” Palliative Medicine, 25(7), 675-681. This is a very interesting article written by A. Cox. The article states how e-technology dramatically increased new ways to obtain the patient’s symptom information, which was self-reported. They conducted study to provide lung cancer patients post palliative radiotherapy.
