4.2.1. Material: Lead zirconate titanate (PZT) PZT is a short for lead zirconate titanate inorganic compound that has a chemical formula of Pb [ZrxTi1-x] O3 (0 ≤ x ≤ 1). PZT is made and composed of the two chemical elements lead and zirconium combined with the chemical compound titanate while formed under extremely high temperatures. The dielectric constant of PZT can range from 300 to 3850, depending upon orientation and doping. PZT possesses piezoelectric effect meaning that it changes shape…

disadvantages of the use of printers? These factors will be discussed during this essay as well as the implications of using static electricity to solve problems such as electrical problems. Static Electricity: Everything in our world is made up of atoms and an atom consists of three parts. In the…

Abstract: My research paper is covering the different theories covering the origins of life. Primordial Soup: The primordial soup theory says that life began in a lake or ocean as a combination of chemicals created amino acids, and from there life evolved. A Russian chemist named A.I. oprin and an English geneticist named J.B.S. Haldane came up with this theory in 1920. to test this theory they collected and mixed elements thought to be on earth at the time and sparked the mixture with…

). “The amount of a pure substance is expressed by the SI base unit of the mole”. One mole of a substance contains 6.02 x10^23 particles of the substance. That number is known as Avogadro’s number ("Amount of." SI Units Explained). “The number of atoms or other particles in a mole is the same for all substances” (The Editors of Encyclopædia Britannica). That…

protons, 11 protons, and about 11 neutrons. Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons to become stable 3. Nucleic acids are organic molecule composed of nucleotides. The role of nucleic acids are to store, express, and transmit…

Temazepam, commonly known as Restoril, is a sleeping pill that is prescribed to patients. This drug is classified under a type of drugs called benozaphines, which are, “a large group of drugs with sedative and anxiety-reducing properties, which have been found valuable for a large number of uses” (UXL Encyclopedia of Drugs and Addictive Substances). This class of drugs is used to reduce anxiety and help with insomnia. Since temazepam is classified as a benzodiazepine, I was curious as to what…

The atomic number to my element is 11, the mass number is 23, the number of neutrons is 12, the protons are 11 and the electrons are also 11, the electron configuration of my element is 1s22s22p63s1. The person who discovered my element is Humphry Davy. He discovered sodium in 1807. Origin of sodium is derived from the English word ‘soda’. The appearance of sodium is soft metal that tarnishes within seconds of being exposed to the air. It also reacts vigorously with water. Used as a…

The purpose of the experiment, “Charge to Mass Ratio for an Electron”, was to measure the charge-to-mass ratio (e/m) for an electron. This lab was performed to help students further understand the characteristics of an electron in regards to various things such as its magnetic field strength and velocity. By using a Daedalon (e/m) Apparatus paired with Helmholtz coils and a glass bulb filled with helium gas, students were able to observe electrons travelling in a circular path. This is due to…

7. If during the experiment an air bubble leaked into the eudiometer tube while it was being inverted in the water bath than the measured volume of hydrogen gas would be off. Ultimately the measured volume of hydrogen gas would be too high because the gas being recorded would not only include hydrogen gas, but the air that leaked into the eudiometer as well. Because the volume of hydrogen gas would be too high the calculated molar volume of hydrogen would also be too high. This is because to…

James Chadwick was born October 20th, 1891 in Bollington, United Kingdom. His parents were John Chadwick and Anne Mary Knowles. He attended Manchester High School and Manchester University (James Chadwick – Biographical, Nobelprize.org). While he was at Manchester University he worked on a research project in Earnest Ruthford’s laboratory. Chadwick finished his project successfully and graduated with first class honors in physics in 1911. He continued to work in Earnest’s laboratory until in…
