Magnesium is a shiny grey solid that assembles to five other elements. Magnesium’s atomic number is 12 and it has 12 neutrons, 12 electrons and 12 protons. Magnesium’s symbol is known as Mg. It is the ninth abundant element in the universe. Magnesium was discovered by Joseph Black in 1775. It was isolated by Sir Humphry Davy in 1808. The name magnesium originates from the greek word for a district in Thessaly called Magnesia. It is related to magnetite and manganese, which too was originated from

Table 1 contains corresponding information to figure 1, as already analyzed, despite having the highest concentrated acid solution, zinc has the lowest output of gas compared to aluminum and magnesium. Looking at the trends, aluminum and magnesium have relatively steady increases of mass and corresponding volume (the amount of gas about doubles as the mass is increased by about 0.02 grams). Zinc, on the other hand, increases by almost triple when the mass is tripled, but levels off after and slowly

reaction of magnesium metal. While heated in the crucible, magnesium reacts with oxygen from the air, and the masses before and after the oxidation are measured. The resulting masses are used to calculate the experimental empirical formula of magnesium oxide. With the empirical formula, we can then compare it to the theoretical empirical formula. Using a crucible and a Bunsen burner, the magnesium metal will be heated to a burning. Simple combustion experiments conducted with crucibles, burners, and balances

According to the definition, Environmental pollution may be defined as the contamination of the physical as well as biological components of the atmosphere thus damaging the environment to a large extent Types of environmental pollution and their sources: Air pollution is considered as the most prolific form of pollution. The main source is burning of fuel which is important for our daily needs such as cooking, driving and industrial activities. Sulphur dioxide, which is very toxic, is produced due

During investigating this plane crash, the materials found at the site were: carbon, hydrogen, nitrogen, and oxygen. In order to identify the victims and what happened, I used empirical and molecular formulas. Empirical formula is a formula with the lowest whole number ratio of elements present in a compound. Molecular formula indicates the actual number of atoms of each element presented in a compound. First, I calculated the empirical formula by using the percentages of the compound analysis for

What is Nitro Coffee Nitro coffee is simply coffee that has been cooled to at least 40C which is equivalent to 400F before being infused with nitrogen. Infusing the nitrogen into the coffee can take different forms. This can be done either through pressurization or through the use of a device known as a Nitrogenator. The Nitrogenator works in a similar manner to how water gets carbonated. Various methods can be utilized in brewing Nitro coffee. The coffee has to be held at a pressure that is at least

The question the group was trying to answer is, “How Does the Total Mass of the Substances Formed as a Result of a Chemical Change Compare With the Total Mass of the Original Substances?” The purpose of this lab was to attempt to verify and observe the Law of Conservation of Mass, and the law of conservation of mass also states that matter is never created nor destroyed. The purpose of this lab was also to prove the the claim that the group made, “The total mass of the substance formed as result

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment, a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion, S2O82-, was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability, coupled with its strong oxidizing ability allowed for stabilization of

Electrophoretic deposition (EPD) is a combination of electrophoresis and deposition techniques. It is a process where charged powder material is dispersed in a solvent before it is attracted by a direct current (DC) electric field and deposited onto a conductive substrate of opposite charge surface (Besra & Liu, 2007). There are two types of electrophoretic depositions; cathodic electrophoretic deposition and anodic electrophoretic deposition. The former occurs when positively charged particles

of a material, specifically calcium silicate, also called limestone. Based on the basic rules of thermodynamics, a hypothesis can be formed that, as limestone is heated, it decomposes into calcium oxide and carbon dioxide due to heat transfer and the creation of impurities. The addition of silicon oxide, or quartz, can also cause limestone to decompose in the same manner. This was tested using experiments including Thermogravimetric Analysis (TGA), Mass Spectrometry (MS), and Differential Scanning
