Double bubble maps

OXYGEN AND NITROGEN



Nitrogen is present in the earth's atmosphere in the greatest number reaching 78%. In nature, nitrogen is not as a free element, but forming a colorless and odorless diatom gas with the N2 molecule formula.
Nitrogen or lymph is a chemical element in the periodic table that has the N symbol and the atomic number 7. This is the lightest technique at room temperature. Usually found as a colorless gas, odorless, tasteless, and a diatomic gas, it is very difficult to react with other elements or compounds. Named a limp because this substance is lazy, inactive reacts with other elements. Nitrogen is a common element in the universe, thought to be the seventh element of total abundance in the Milky Way and the Solar System. On Earth, this element makes up about 78% of the Earth's atmosphere and is thus the most abundant free element. The nitrogen element was discovered as a component that could be separated from the air, by Scottish physicist Daniel Rutherford, in 1772.
In addition to filling 78.08 percent of Earth's atmosphere, nitrogen is present in many living tissues. Substances form many important compounds such as amino acids, ammonia, nitric acid, and cyanide.
The role of nitrogen in the industry is relatively large, and industries that use nitrogen as the basic ingredient are also referred to as the nitrogen industry. Air-derived nitrogen is a major component of fertilizer manufacturing and has greatly assisted in the intensification of food production worldwide. The development of the nitrogen fixation process has succeeded in clarifying the various principles of chemical processes, and high pressure processes and has contributed much to the development of chemical engineering.
Prior to the synthetic nitrogen fixation process, the main source of nitrogen for agricultural purposes is only waste material, and animal waste, the decomposition of these materials and ammonium sulphate obtained from the by-products of coking from coal. Materials such as these are not easily handled not to mention the insufficient amount of all the necessary needs.
Chilean salpeter, salpeter from animal urine, and humans, and ammonia collected from coke making have become important these days but are ultimately set aside again by synthetic ammonia, and nitrates. Ammonia is the base material for the manufacture of almost all types of products that use nitrogen.


HISTORY OF OXYGEN
Oxygen (O2) is the 3rd most abundant chemical element on earth. Oxygen is often called diatomic gas compound with the formula O2 is colorless, tasteless, and odorless. Diatomic oxygen gas fills 20.9% of the Earth's atmospheric volume, oxygen or acidic substances as well as parts of Chemistry. The oxygen in the order of the periodic table is at atomic number 8, is a catalytic element and can easily react with almost any other element. Oxygen separately was discovered by Carl Wilhelm Scheele at Uppsala in 1773 and Joseph Priestley in Wiltshire in 1774.

Priestley's findings are more famous because the publications are the first printed. In his findings Joseph Priestley directs sunlight on mercury (II) oxide so that it breaks down into mercury and oxygen gas. Priestley found that the candle flame was brighter in Oxygen gas than in ordinary air. Shortly after this discovery, Lavoiser discovered that the increasing mass of metal burned in the air is nothing else because it binds Oxygen. The name Oxygen itself is given by Lavoiser on the assumption that the element is present in all acids (Oxygen: acid-forming).

  1. why we should use double bubble map to explain about compare and contrast?

    1. Because double bubble maps make it easy to compare two things and can give an explanation of the difference between the two

  2. Which one is the most abundant in the world, and why

    1. We know that all living things on Earth need Oxygen to perform the process of respiration, and of course this we need enough oxygen to support the metabolic process. Why did not God give Oxygen gas with a percentage, just 21%? Why is Nitrogen the best gas in terms of its levels in Earth's atmosphere? Nitrogen is one of the chemical elements in the periodic table that has the N symbol with its atomic number 7. Nitrogen is heard in colorless, odorless, and flavored gas which is a stable, non-metallic, diatomic gas. The Oxygen itself is one of the elements in the system of the periodic table with the atomic number 8. At the standard temperatures and pressures, the two atoms of this element will bind then will be a colorless, tasteless, and smelly dioxygen (O2). Indeed, Nitrogen diatmosfer the earth far more than Oxygen, but remember we can not enter the relative amounts between Oxygen and Nitrogen that exist throughout the earth. In fact, the relative amount of Oxygen around the earth is much more abundant than Nitrogen. Abundance in this earth is the composition of our earth material is made and the process of earth accretion. Oxygen is a major component of solid earth, together with Si, Mg, Ca, Na. Nitrogen itself is unstable to be part of the crystal lattice because it does not form on the earth padar, and for this reason Nitrogen enriched and reproduced in the atmosphere of the earth (because Nitrogen function is also not less important than Oxygen to support life as the element of making amino acids as a basic architectural of proteins ). Well, Nitorogen is unstable to be part of the crystal lattice, but it is very stable in the Earth's atmosphere unlike the unstable Oxygen and is in the process of various chemical reactions there. Nitrogen is also very stable with solar radiation.

  3. What character is typical of both elements ?

    1. Characteristic of the nitrogen element is the most common element in the world while the oxygen element is ranked second after nitrogen and oxygen are the most needed elements of humans to live their lives
