Magnesium Magnesium is one of the best elements you can own it’s a 3rd period element its part of the alkaline earth metal family. Magnesium is a metal and it’s a solid, with a isotope of 24 and really high energy level. Buy magnesium it’s going to be your favorite purchase you will ever make you won’t regret it. Magnesium was discovered in 1808 by a guy named Sir Humphrey Davy but it was first experimented by joseph black. The Country it was discovered in was England in the United Kingdom.…

In this lab, students learned that in a combination reaction, two or more substances react to form one substance. This can be seen in reaction #2. In reaction #2, magnesium reacts with oxygen to produce magnesium oxide. Although the students can only see magnesium and magnesium oxide, the students were informed on the lab sheet that oxygen was also one of the reactants. This reaction allowed students to see how two substances, magnesium and oxygen, react to produce one product, magnesium oxide.…

The production rate of S2O32- when SoxF metabolized sulfide was similar to that of the wild strain C. pinatubonensis JMP134 (Fig. 2), indicated that knockout of SoxF did not affect the function of the SQR/PDO/ST system. In addition, the double knockout strain CpSQR&SoxF produced almost the same amount of S2O32- and SO42- compared with CpSQR (Fig.S3), which also showed that SoxF did not participated in the oxidation of sulfide. Interestingly, the re-consumption rate of S2O32- (Fig. 2, F),…

The purpose of the experiment is to determine the equilibrium constant of the reaction between Fe3+ ions and SCN2+ ions. In solutions one to five (the reference solutions), a large volume of concentrated Fe3+ ions was used in order to react with and convert all of the SCN2+ ions into FeSCN2+ ions. In solutions six to ten (the test solutions), a constant volume of Fe3+--in lesser concentration--and varying volumes of SCN2+ ions were diluted with DI water and reacted to produce an unknown amount…

Fluorite, also called fluorspar, is a mineral that is composed of calcium and fluorine. Pure fluorite is colorless. Fluorite is known as the most colorful mineral in the world. Each colored fluorite has its own name. The most common colors for fluorite come in purple, blue, yellow, or green (King, Fluorite.) What makes fluorite colorful depends on what elements are substituting calcium in the crystalline structure. Fluorite is an interesting mineral because of its wide range of uses. People use…

Martha Garcia November 10, 2017 Chemical Weathering Background Chemical Weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. It occurs in almost all types of rocks, smaller rocks are susceptible, because they have greater surface area, more common where water is, because water is important to many of the chemical reactions, when water is slightly acidic, which is called ocean acidification. Ocean acidification is…

What is chlorine and how does it have an impact on humans’ health and the environment? Chlorine is a chemical element that was discovered by Carl Wilhelm Scheele in 1774. Its symbol is Cl and its atomic number is 17. Chlorine has the physical form of a diatomic greenish-yellow gas at room temperature and atmospheric pressure. 1. 2. Indeed, its name is derived from the Greek word ‘chloros’, meaning ‘yellow-green’. 3. In the Periodic Table of Elements, Chlorine is found in the P-block, in group…

Scientist Contribution Significance Lavoisier (1743-1794) Antonie-Laurent Lavoisier was born on August 26, 1743 in France’s capital city, Paris. One of his major discoveries was the founding of the law of conservation of mass. This law states the weights of reagents and products are conserved through any chemical reactions. This is demonstrated through his combustion experiments. He pointed out that combustion requires air, since the reactants are weighed heavier than its products. This…

The elements sodium and chlorine show emergent properties, because when sodium is alone it's just a metal and chlorine is a poisonous gas. When you combine the two with an ionic bond the emergent properties are shown, because they come together to form table salt, but on their own this wouldn't be possible. 2.1.2) Yes, even though organisms only require it in small amounts it is still essential because it contributes to the organism's development. 2.1.3) If a person has an iron deficiency it…

the process of nuclear fusion. Stage Six: Nuclear Fusion Ten million years after the shock wave, the star is officially born when it reaches an internal temperature of 10 million degrees Kelvin. At this pivotal temperature, the individual hydrogen protons are unable to repel each other any longer, and collide into each other forming a helium atom. This process not only forms a higher element, but also releases energy. It is this energy that we see as sunshine or light, and can feel as…
