In this experiment, we are using Calcium, Aluminum, and Magnesium to test our theory about periodic trends. We put these 3 metals through different tests to show why elements in similar group and period react differently. The purpose for this lab is to test the idea of patterns in the periodic trend, and if elements in similar group or similar period react differently due to the trend that they follow. If two elements in the same group or family are to be tested, one of the element reactivity…

radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance. Stars 1. So creating a brand new element requires loading an atom's nucleus with more protons. Stars create new elements in their cores by squeezing…

The element Magnesium got its name when it was discovered. It is a silvery white metal that is highly reactive. Its chemical symbol is Mg and atomic number is 12. Its atomic mass is relatively 24. Therefore, it has 12 protons, 12 neutrons, and 12 electrons. According to Steve Gagnon in “The Element Magnesium” Magnesium was isolated by Sir Humphry Davy, an English chemist, through the electrolysis of a mixture of magnesium oxide and mercuric oxide in 1808. Magnesium has a melting point of 650°…

Despite the practical and informative nature of the Williamson ether synthesis of 2-bromo-4-methoxy-phenoxy benzyl ether. This reaction was not conducted due to an error made in which the initial product was thrown away instead the actual second phase of this synthesis was the Williamson Ether synthesis of 4-methoxy-phenoxy benzyl ether. Figure 4. Williamson Ether Synthesis 4-methoxy-phenoxy benzyl ether ____________________________________¬___ In spite of this outcome there was still much…

Call it what you will. An artificial forest. A hide-and-seek campground. A scientific laboratory. Maybe even Owens Valley Long Wavelength Array. Exciting discoveries are taking place here in Owens Valley. A large array of radio telescopes, designed in the shape of trees, lay scattered across the desert floor, making it look just like a dry forest, artificially. Of course, it would be nice to play a game of hide-and-seek there, hiding between 288 distinct radio antennas under the warm sun.…

The Big Bang theory is a theory scientists use to explain the creation of the universe. According to this theory, the universe was concentrated into a single point 13.7 billion years ago. This theory states that the universe started as a singularity. Time began when this single point exploded causing the expansion of the universe. This expansion formed matter, energy, space, and time. In 1915, Albert Einstein applied his theory of General Relativity to how the universe began. General Relativity…

Name: Hiatal hernia Outline: A hiatal hernia happens when the upper piece of your stomach pushes up through your stomach and into you're midsection. The stomach is an extensive muscle that lies between your midriff and midsection. You utilize this muscle to help you relax. Ordinarily, your stomach is beneath the stomach. Be that as it may, in individuals with a hiatal hernia, a segment of the stomach pushes up through the muscle. The opening it travels through is known as a break. This…

Chlorine is an element that consists of 17 protons, an average of 18.5 neutrons and 17 electrons. It has an atomic number of 17, and an average nuclear charge of 35.5. There are 2 isotopes of chlorine that are 35Cl and 37Cl. 35Cl has an atomic mass of 35 and a natural abundance of 75%. 37Cl has an atomic mass of 37 and a natural abundance of 25%. The average atomic mass or nuclear charge equates to 35.5. Both of the isotopes have the same atomic number. (BBC Bitesize. Atoms and the periodic…

electron transport chain, hydrogen ions are pumped across the membrane creating a chemiosmotic gradient.”(“How Do Mitochondria Use Chemiosmotic Gradients”). Basically, the chemiosmotic gradient drives the electron transport chain. The energy used from proton diffusion transforms ADP into…

reduce the risk of development of hepatorenal syndrome by decreasing the risk of renal dysfunction.2 In addition, patient BB is currently taking pantoprazole 40 mg PO daily. Current practice guidelines recommend that cirrhosis patients should not use proton-pump inhibitors (PPIs) without a significant clinical indication. Many studies have shown evidence that the use of PPIs in cirrhosis patients cause an increase in the risk of developing SBP.2…
