Hydrogen cyanide

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.…

Background research: Redox reactions includes the two reactions called oxidation and reduction. Oxidation is defined as the loss of electrons, loss of hydrogen and gain of oxygen. Reduction, on the other hand, is defined as the gain of electrons, gain of hydrogen and loss of oxygen. Oxidation occurs when there is an increase in oxidation numbers and reduction occurs when there is a decrease in oxidation numbers. Oxidation numbers are values assigned to an atom in a compound which measures the…

Introduction: DNP and research question The organic compound 2,4-dinitrophenol (DNP) is a crystalline solid with the molecular formula C6H4N2O5. The molecule is soluble in water to some extent and is fully soluble in sodium and potassium hydroxide solutions. The compound can also be explosive. It is usually used in dye, weed killers, wood preserver, photographic development among other things and it has even been used as a weight loss agent. In fact, it has been claimed to be the king of the…

The 1HNMR of chloro (pyridine) cobaloxime (III) showed all the characteristic peaks of the product. It had very few peaks and is very tidy. This shows that the molecule has high symmetry. The large singlet peak at 2.5ppm, corresponds to the 4 methyl groups that are connected to the double bond N of the dimethylglyoxime. It integrates to 12 H’s. These methyl groups are accounted for at a higher ppm that usual. This could be due to the fact they are doubly bonded to the electronegative Nitrogen…

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…

The sharpie permanent marker a tool used to write things were they could stay permanently or not be addressed.But what people don't know is what they contain.Sharpies contain” Dyes, Propyl alcohol,Butyl alcohol and Diacetone alcohol”.(wikipedia).Propyl alcohol also known as 1-Propanol,(Wikipedia) is i on of the ingredients in a sharpie.Did you know that 1-Propanol “is formed naturally in small amounts during many fermentation processes and used as a solvent in the pharmaceutical industry…

In this lab, the main question is, what is the ideal ratio of Alka-Seltzer to water that will produce the longest canister flight time? In the first experiment, we asked, what amount of water will produce the longest canister flight time? In the second experiment, the question was, what amount of Alka-Seltzer will produce the longest canister flight time? The main reason this lab was split into two parts was because there can only be one independent variable per lab, therefore, the water and…

Single Replacement Reactions and Double Replacement Reactions A chemical reaction is a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The evolution of energy as heat and light, production of gas, formation of a precipitate, and color change are 4 indicators of a chemical reaction. Two out of the six types of reactions are the single and the double replacement reactions. During single…

Why small covalent substances have different properties from macro molecules? • Simple covalent substances will only contain a few atoms that are held by strong covalent bonds for example co2 the molecules contain one atom of carbon that is bonded with 2 oxygen atoms. The intermolecular forces causes the small covalent structures to have a low melting/boiling points, they don’t conduct electricity because they don’t have any free electrons or an electric charge overall. • Macro molecules will…

chemical properties. The gas we got was hydrogen. Hydrogen is a chemical element with the atomic number 1, and has the chemical symbol of H. It is known to be very flammable, and it is also used as a fuel source for a space shuttle’s main engine. So when the fire lit inside the tube, the hydrogen reacted and created a flame strong enough to produce a loud sound and a flash. 4.Although this is highly unadvisable, any liquid inside of a bottle of hydrogen peroxide can be swallowed as long as the…
