Solid

Of the most abundant elements together 98 percent of the 8 elements form the mass of the earth’s crust, ocean and atmosphere. Two of the most abundant elements of the eight are calcium and magnesium. Calcium and magnesium are located on the periodic table located both in group 2 sharing the same family meaning that they share chemical property’s as well as the same valence electron because of their location and family relation to the period table. The alkaline metals are a reactive group of…

This value is comparable to the CRC Ksp, which is 5.02×〖10〗^(-6). Our calculated value is slightly larger than the literature value because of our experimental error. Some of this error came from the different methods that we chose to separate the solid calcium from the hydroxide solution. The three methods that we used were decanting, separation by centrifuge, and filtration with filter paper. According to the CRC Handbook, the expected concentration at 20 degrees Celsius of dissolved calcium…

by a polymeric membrane, and nanospheres are composed of a cosmetic ingredient dispersed through a sphere (see above picture) [4]. Solid lipid nanoparticles (SLN) have also been found to be especially useful in the formulation industry. Solid lipid nanoparticles differ in their composition and preparation methods. In the most general terms they are composed of solid lipid, emulsifiers, and water/solvent [7]. They can be prepared by various techniques including, but not limited to, high shear…

statistics would sound more reliable compared to Baldwin’s. Consequently, the authors’ social titles supports their writings with ethos. Baldwin’s op/ed which explains about the significance of boredom is mostly based on his own experiences rather than solid facts. The author uses personal anecdotes of how he was benefited from experiencing boredom to develop his…

the Pythagorean Theorem; this is important because the Pythagorean Theorem is still taught in most math classes today. He also made discoveries such as: the five regular solids, construction of given areas and geometrical algebra. Pythagoras thought the stars, planets, and universes were round because a sphere was the best solid figure. He was also one of the first philosophers to state that the earth is a sphere and that the earth revolves around the sun(Brunschwig 721). Euclid is important…

In 1970 geologists Kenneth J. Hsu and William B.F. Ryan were collecting research data while aboard the oceanographic research vessel Glomar Challenger. An objective of this particular cruise was to investigate the floor of the Mediterranean and to resolve questions about its geologic history. One question was related to evidence that the invertebrate fauna (animals without spines) of the Mediterranean had changed abruptly about 6 million years ago. Most of the older organisms were nearly wiped…

forms the test is positive. The triiodide test requires a visual inspection and if the colors are orange, brown or red the test is positive. The zinc ion test requires the solids to be dissolved in 2-3 mL of water (if a precipitate forms .17 M acetic acid should be added) and then to add 1 magnesium turning. If a fine black solid is deposited on the surface the test is positive. Finally the test for zinc metal requires 3 drops of 3 M HCl solution to be added to the test tube and if hydrogen gas…

1.Please explain how medical magnetic resonance imaging (MRI) exploits the magnetic properties of the nucleus. MRI exploits the process known as nuclear magnetic resonance (NMR). In fact the technique used to be called simply NMR or NMR imaging, but the “nuclear” was dropped because of the connotation of radiation hazards from unstable nuclear sources, although there is no logical rationale for such fear. In NMR, a sample of material is placed in a strong magnetic field. The nuclei in the sample…

the burden of planning for college and highlighting my baseball skills for college coaches. However, this setback has not deterred me from achieving a solid academic record and realizing success on the baseball field. I have chosen to study economics as my primary academic focus, and I feel Creighton’s Heider College of Business will provide a solid educational foundation for my future. Another reason for selecting Creighton is their history as a Catholic university. Creighton's Catholic…

emissions testing program half a decade ago. Newer, EPA certified, biomass/solid fuel heaters are replacing the older models and the advancement of sophisticated masonry heater technology has also led to a decrease of PM 2.5. Carbon monoxide if far less of a problem than it was 20 years ago. To help the air quality improve, the Borough and State have initiated a wood stove buy-out program and have also made selling a home with a solid fuel burning appliance difficult. Removal of these systems is…
