Paragraph 1 This essay will evaluate the Haines et al. Also, the essay will discuss about how the structure of FePO4 will change at various temperature ranging from 294K to 1073K. FePO4's A cation is a transition metal, thus it is not the same as other α-quartz isotopes. FePO4' has α-quartz structure which is tetrahedral when it is at a very low temperature. Under huge pressure, FePO4's structure goes through a phenomena called β-phase which it became a more condensed octahedral structure.…

Heterogeneous and Homogeneous mixtures Objectives: To understand definition of mixture and types of mixtures, i.e Heterogeneous and Homogeneous mixtures Matter is, made up of small particles (solid, liquid or gas). These small particles make up substances that can be pure substances such as Mercury, Iron, gold biscuits or mixtures such as air we breathe, food we eat and water we drink. A substance is a kind of matter that cannot be separated into other kind of matter by any physical process.…

of energy. Roentgen found that very penetrating radiations were produced from the anode, which he called x-rays. In an X-ray machine, a stream of highly charged electrons is made to strike a metal target. This arouses some of the electrons in the atoms of the target material. In the process of giving off the excess energy thus gained, the atomic electrons send out Xrays(see fig.2). The principal uses of x-rays are in the field of scientific research, industry, and medicine. Advanced and…

The Quantum-Mechanical Model of the Atom Introduction: The theory of quantum mechanics explains the behavior of the particles, such as photons (particles of light) and electrons, in the atomic and subatomic realms. Since the electrons of an atom determine many of its chemical and physical properties, quantum mechanics is foundational to understanding chemistry. Quantum-Mechanical Model- a model that explains the strange behavior of electrons Electromagnetic Radiation- a type of energy…

The purpose of the lab was to determine which unknown substances were ionic compounds, if any, using 4 different methods. This lab was to determine which of the three unknown substances (X, Y & Z) are ionic compounds and which are not ionic compounds. In conclusion unknown Y is an ionic compound and unknown X and Z are not ionic compounds. In order for a substance to be an ionic compound it must have a high melting point, it must be brittle, it must be soluble in water, it can not conduct…

PE2008 – Phase Equilibrium Thermodynamics Assignment Kayleigh Tobin – 114378781 Separation of Water and Pyridine by Distillation.________________________ (1) Water – H2O • Density: 1,000 kg/m³ • Boiling point: 100 °C • Molar mass: 18.01528 g/mol • Melting point: 0 °C • Formula: H2O • IUPAC ID: Water, Oxidane Water is the most abundant compound on the planet’s surface. Water exists naturally in a liquid, solid and gaseous form. The liquid phase of water is the most common. The solid phase…

Figure1.3: Band gap vs lattice constants diagram for hexagonal nitride compounds. The typical of measured band gap bowing for ternary alloys AlGaN and InGaN is shown by the solid line track[21]. 1.4. Unique Material properties of Gallium Nitride: The unique material properties of GaN engraves it as an prominent semiconductor material for many electronic and optoelectronic devices[18]. • The wide and direct energy band gap sorts GaN as an appropriate materials for device fabrication in the field…

If you consider quartz, it is quite similar too with the positive charge from Si4+ which is 4+. And thus with 2 Si atoms in it, total positive charges will be 8+. As you have noticed, if we replaced the 2 Si atoms with 1 Fe atom and 1 P atom, they will also be able to create bonds with the O atom without any notable changes in the structure. Furthermore, by heating up SiO2, it would demonstrate the α phase at low temperatures and the β phase at high temperatures…

science that reviews the properties of stereoisomers. It can likewise be characterized as the branch of chemistry concerned about the three-dimensional course of action of particles and atoms and the impact of this on concoction responses. A critical branch of stereochemistry is the investigation of chiral atoms. Stereochemistry is otherwise called 3D science in light of the fact that the prefix "stereo-" signifies "three-dimensionality". The primary investigation of stereochemistry is on…
