Solid mechanics

Solid solubility is whether that solid can dissolve in specific solvent or not. When a solid dissolve, the ions that comprise the solid will disperse in the solvent thus create a different concentration distribution within the solvent solution. Thus we can view this as a flow of ion from high concentration to low concentration (there’s a flow of ions) Electrical activity is the ability for electron to travel within the material. Specific solid material molecule will have free electrons to…

The main purpose of this experiment is to purify an impure solid by the technique of recrystallization. This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent…

Paragraph 1 (300 - 500 words) Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4 To compare quartz, α-FePO4 and β-FePO4, it is essential to look at their crystal structures and crystal chemistry. This can be done by observing their three-dimensional structures as well as their reactions to various degrees of temperature. This particular research takes a look at the structure of FePO4 between temperatures of 294K to 1073K. At lower temperatures,…

Title: What was the effect of different types of salt on height of ice cream formation? Purpose The purpose of this experiment was to find out if there was any correlation between different types of salt and the final height of ice cream formations. Background Information Milk is made up of triglycerides (mainly milkfat) dispersed throughout water as an oil-in-water emulsion, or dispersion of globules of one liquid into another. When agitated, the emulsion begins to break down, or coalesce…

and Boiling Points: The particles/substances which are present in a metal are held or joined together by strong metallic bonds. A lot of energy is used to separate these particles. That is why metals have high melting and boiling point. Metals are solid as well as crystalline. They are arranged in a regular pattern and are held closed together. 2. Electrical Conductivity: Metals conduct electricity. The sea of delocalized electrons are mobile and are free to move around in the 3D structure of…

Methods and Materials 0.4g maleic anhydride and 1ml ethyl acetate was added to a test tube and mixed until dissolved. 2ml hexane was then added to the test tube, followed by 0.4ml cyclopentadiene. The test tube reacted for 5 minutes in a test tube rack and then 2 minutes in an ice-bath to allow for complete crystallization. The crystals were then put through the filtering apparatus to collect and dry all the crystals. About 3ml was used to rinse the crystals while in the apparatus. The…

an example of crystalline structure. When the water begins evaporating, the amount of salt stays the same. As water evaporates, the salt molecules are pushed even more closely together, which causes more salt out of the water and into a solid form. The solid form will then come into a salt crystal. When most of the water evaporates, there is no water left, because of this, the salt crystals begin to form. If the water does not evaporate fast, the salt crystals will take more time until the…

Elizabeth Lee James Poland CHEM 104A 21 September 2014 Discussion and Conclusion of Experiment #4: States of Matter Sleuth Discussion The results of this experiment enabled the experimenter to determine the identity of an unknown salt (#3) using ion-exchange chromatography by analyzing the inorganic salts of the unknown salt, which can be examined by acid-base titration using ion-exchange resin. The stationary phase is made up of acid groups which will attach to the resin, which is then rinsed…

During the first century B.C., the Phoenicians invented glass blowing "in the vicinity of the Palestinian coast" (History of Glass). Used for jewelry, decorative pieces, or vessels, blown glass has been a significant type of glass, having been practiced by numerous cultures across the world. However, glass blowing is a tedious task, requiring "extreme patience, tenacity, and dexterity" and is a long, multi-step process (Sacramento Art Glass). Over time, the difficulty of these numerous steps has…

technician is a great job for someone who wants to work on and learn about cars, wants a solid salary and wants terrific job security. One benefit of being an automotive technician is that you get to work on and learn about cars and their technology. As an automotive technician you will be able to repair, maintain and diagnose many different brands and types of cars (Automotive service technicians and mechanics.) As a technician, they have the option to take a test on state inspection. If the…
