Red Dye 1 Red dye 1 is most likely a polar covalent molecule since we have found that it dissolves into water but does not break apart into ions. Just because it dissolves in water does not make it solely polar covalent, but since it has a relatively low conductivity, 534 mS/cm in the 0-20000 range, then it most likely is polar covalent. This is further confirmed with the fact that it does not react with NaOH, NaCl, or AgNO3, all ionic substances. The red dye does not react with NaOH since…

more focused on the study of the properties of matter as well as the interaction between various types of matter. The interaction is often facilitated by the reactions that involve either electron loss or electron gain, as described by the American Chemical Society (2014). Unlike other sciences, such as physics, chemistry doesn’t put more focus on the nuclear part of the atom, and any other subatomic realm. Perhaps it’s important to emphasize that chemistry is a science, and thus the procedures…

Case studies Many cases in the literature have utilized CT imaging to address bioarchaeological questions; however, predominately they focus on mummification studies, with only a few cases in reference to bone specifically. One such case was in the article Non-invasive Archaeology of Skeletal Material by CT scanning and Three-dimensional Reconstruction by Lynnerup et al. (1997). In this case the skeletal remains are of a very fragile and delicate 7000 year old ancient Sumerian skeleton that was…

printing has made its presence known within mainstream media. The first appearance of 3d printing in modern cinematography was released in 1998. The movie was titled “Small Soldiers” and it featured a scene where a toy was made layer by layer due to a laser, much like how a SLA printer functions. SLA printers are one of many different types of 3d printing commonly available today. The other most notable variety of 3d printing is FDM. FDM printers and SLA Printers function in relatively the same…

3D printing is a mechanical process where solid objects are created by ‘printing’ successive layers of material to replicate a shape modeled in a computer has been adopted in numerous industries. Many people can benefit from this kind of technology such as wounded warriors that may have lost limbs in combat, or even those that have dysfunctional organs and could use a new organ. The creator of 3D printing, Charles Hull, on August 8th 1984 filed for a patent on his photo solidification apparatus.…

Gallium is one of those elements that is used in industry every day. Gallium was discovered in Paris at the private laboratory of Paul-Emile Lecoq de Boisbaudran (1831-1912) at 3 a.m. on August, 1875. He observed a new violet line in the atomic spectrum of some zinc he had extracted from a sample of zinc blende ore (ZnS) from the Pyrenees. He knew it meant that an unknown element was present. Gallium comes from Gallia, the Latin name for France. Gallium also has origins in the Latin word Gallus.…

The most recent example of this idea of duplication as opposed to original generation is the modern phenomenon of three-dimensional or 3D printing. There has been a huge amount of interest following 3D printing as it has transcended from a futuristic figment of the imagination to a shelf-stocked product in a number of years and can be purchased today from just €230. The incredibly innovative sensation that is 3D printing is seen to be completely ahead of its time and to have come out of nowhere.…

CH 204 – Introduction to Chemical Practice Experiment 10 – Kinetics Joshua Fu* Tien Tran TA: Jamie Trindell April 25, 2016 INTRODUCTION This experiment focused on the concept of chemical kinetics, which describes the speed at which a chemical reaction occurs and the amount of reactant or product remaining after a specific period of time. Kinetics is important in analyzing the rates of certain species and reactions, and is a crucial technique to predict different reactions. Kinetics is…

unit. The interface transfers the analyte in solution phase from the LC column to the high vacuum of the MS as a single molecule in the gas phase. Two interfaces will be discussed: Electrospray Ionisation Interface (ESI) Atmospheric Pressure Chemical Ionisation (APCI) Interface Electrospray Ionisation Interface (ESI) Figure 2: Schematic Diagram of Electrospray Ionisation…

New method of synthesis of oligoetherols with carbazole ring Renata Lubczak Abstract: The new method of synthesis of multifuntional oligoetherols with carbazole ring suitable for obtaining the polyurethane foams of enhanced thermal resistance was presented. At the first step of the synthesis the carbazole was reacted with excess glycidol to obtain the product of (n +1) functionality, where n is number of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without…
