USING ENLISH TO COMPARE AND CONTRAST THE ELEMENT



COMPARE AND CONTRAST

1. Understanding of compare and contrast
Compare and contrast are compositions that explain the ways in which two (or, very rarely, more) objects are the same or different
In this paper, we will discuss how to compare and describe the similarities between objects. When we compare Uberman and Catman, we may describe their tragic backstories, their double secret lives, and their fondness for fighting evil. Basically, the comparison tells what they have in common
The opposite of comparing is contrast. When you contrast two things, you explain the way in which they are different. Contrast Catman and Uberman, we might note the way Catman uses his opponent's power against him, while Uberman depends on violence
So it can be concluded Compare is a level that focuses on equations or levels of "positive" while the contrast is a level that emphasize the difference

2.  Compare and contrast Magnesium and Barium
A. Magnesium
Magnesium is a chemical element in the periodic table that has the symbol Mg and atomic number 12. Magnesium belongs to the class IIA, which is an alkaline earth metal element. Magnesium has a shiny gray color and is included in a solid element. Magnesium also has an oxidation rate of 2
Magnesium is the eighth largest element that makes up 2% of the earth's crust, and is the third most dissolved element in seawater. The alkaline earth metal is mainly used as an alloy to make the aluminum-magnesium alloy often called "magnalium" or "magnelium"

  B. Barium
Barium is a chemical element in the periodic table that has the symbol Ba and the atomic number 56. Barium belongs to the class IIA, which is an alkaline earth metal element. Barium has a silver gray color and is included in a solid element. Barium also has an oxidation rate of 2
Examples of crystals produced by Barium include Barium sulfate (BaSO4) and Barium hydroxide (B (OH) 2) base examples. Some barium compounds are easily soluble in water and are found in lakes or rivers

  1. Please describe in more detail the differences in physical properties of Mg and Ba!

    1. Magnesium is one type of light metal with the same characteristic as aluminum but magnesium has a liquid point lower than aluminum. As with aluminum, magnesium is also very easy to interfere with air (Oksgen). While Barium is a silver white metal, can be forged and clay, which is stable in dry air. Barium reacts with water in humid air

  2. Why does magnesium react slowly with water while barium reacts quickly?

    1. Because Alkali metals react with water to form hydroxide compounds and H2 gas.
      If M is an alkali metal, then the reaction can be written as follows:
      2M (s) + H2O (l) 2MOH (aq) + H2 (g)
      The reaction progresses with the increase of atomic number from Li to Cs. This is caused in a group from top to bottom the number of skin more and more so the more easily remove the outer electrons that will be used to bind to other elements or compounds.

    1. Magnesium is quite hard, silvery white. This is the lightest of all structural metals. The metal is strong enough to be used for building buildings, bridges, cars, and airplanes. Magnesium is easily formed. Magnesium metal can be formed by forging, bending, cutting, coupled and combined with other metals. Metals should be made before they can be converted into useful products. Strong, tough, or hard metals are not easy to make. They must be made into a blend. A metal that is more easily made (such as magnesium) is combined with the metal. The melting point of magnesium is 651 ° C (1200 ° F) and the boiling point is 1,100 ° C (2,000 ° F). The density is 1.738 grams per cubic centimeter whereas the atomic number 56, the solid phase, the density (g / cm3) 3,59, the Ionization Energy I, kJ / mol 453, the Ionization Energy II, kJ / mol 908, electron value 0.89, Standard -2.90 Atomic radius, A0 2.22, Heat capacity, J / gK 0.204, Ionization potential, Volt 5.212, Electrical conductivity, ohm-cm- 2.8 x 106
