Assignment: Chemistry of Magnesium and Silicon Magnesium Properties Magnesium is a group is a group 2 element with the symbol, Mg, an atomic number of 12 and has a molar mass of 24.31 [1]. It is made up of 12 protons, 12 neutrons, and 12 electrons. It’s electron configuration is 1s2,2s2,2p6,3s2 this given as noble gas configuration is [Ne]3s2. It has a melting point of 650 °C and a boiling point of 1090 °C [2]. It has a metallic radius of 150 pm, a coordination number of 72(6), and a density of…

Not Every Salons Are identical Your skin may be the body's biggest organ and just how we take care of it'll influence our overall health and well-being. Your salon ought to be the place in which you obtain professional skin analysis, effective remedies (that provide you visible results) and splendid indulging. "7 Tips" on Selecting Your Salon: TIP 1: One particular strategy is to request your buddies or individuals the neighbourhood. Recommendations are a way that will help you choose your…

Task 3: Explain standard solutions and at least 3 different types of titrations that are used in industry and compare these to titrations in the lab. Standard Solutions & Titrations A standard solution is a solution of a known concentration. Standard solutions are made by dissolving an accurately weighed mass of a solid in a known volume of a soluble solvent using a volumetric flask. Method • Firstly, you would need to calculate the mass of the NaOH that you are going use. • Next you…

Potassium is everywhere. It races through the bloodstream, drifts in the air, swims through the water, and rises up roots of plants. Furthermore, it is vital for life to exist on earth, from the grass lions, bears, and humans trample on every day, to the fish and plankton in the ocean. Without potassium, the ninetieth element on the periodic table with chemical symbol “K,” life would be immensely different today, notwithstanding any in the first place. Potassium functions a significant role in…

throughout the day. If there was no sun for a couple of days, the wind turbine will generate the energy. The extra energy generated by the solar panels and wind turbines will be used to power the hydrogen generator which is going to split the water by electrolysis generating hydrogen. If there is no wind or sun, then the generator powered by hydrogen will kick in. Although the costs of these machines added together will be high, it will pay off in the long run. 5 kW (kilowatt) solar panels…

Acid rain is any form of precipitation that has unusually high acidity (a pH level below 5.6) and caused by the transformation of nitrogen oxides and sulfur dioxide into secondary pollutants. pH is is a scale used that measures the acidity of liquids and ranged from 0 to 14. The lower the number, the higher acidity, or the higher concentration of hydrogen ions. 0-5 is considered acidic and as you move up to 7, this indicates the substance is neutral. The higher numbers on the scale indicate…

Abstract The paper present the investigation on the effect of temperature, time and current density on surface roughness in electropolishing process on 316L stainless steel. The cathode material under study was 316L stainless steel. The electrolyte was composed of sulfuric acid, phosphoric acid, and DI water. Full factorial design method was used. ANNOVA technique has been used to assess the quantitative influence of the different process factors of the EP. The surface roughness will be…

The objective of Chapter 6: Compounds and Elements was to determine how to synthesize and decompose pure substances, distinguish the difference between compounds and elements, and to determine the difference between complete and incomplete reactions. Previous chapters that contained valuable background knowledge were Chapter 2: Mass Changes in Closed Systems and Chapter 5: The Separation of Mixtures. The Law of Conservation of Mass, which was tested in Chapter 2, proved to be vital in this…

OJ Simpson - actor, athlete, and killer. After the brutal murder of his ex-wife, police were sure the evidence would convict him. However, numerous mistakes were made in the collection and handling of evidence. This was not enough to derail the investigation, OJ was clearly still the culprit, but it was enough to place doubt in the juror’s minds. If the evidence had been collected and handled correctly, Simpson would have gone to jail for his misdeeds. Orenthal James Simpson, or OJ for…

How Does Temperature (thermal kinetic energy) Affect the Phases of Matter? Observation Can matter be in anything that elements can mix to something different? Why does matter have to have more than 2 elements? What things do not have matter? Why does matter have to have more of, weight, volume or density? Why is there such things called matter? Why is the earth made of matter? How much does matter influence the earth and what it does to help? What is matter? How does…
