Nitrogen is a colorless, odorless gas that can be found in group 15 of the periodic table. Nitrogen is represented by the symbol, N, and has an atomic number of 7. This element was discovered by Daniel Rutherford in 1772. Mr. Rutherford studied Edinburgh University where he began his research on this gas. It started with an experiment including a mouse in a small enclosed area, and from there concluded that the air being released by the mouse was what we know as Nitrogen. At room temperature this element is a gas. Nitrogen has an atomic number of 7, and its isotopes number 14. Other important things to note about this element is the electron configuration which is [He]2s^22p^3, as well as its density which numbers 1035 K.
Nitrous oxide, symbolized by N2O is one of the compounds formed by Nitrogen. This compound was discovered in 1776 by Joseph Priestley. This compound is actually a very easy compound to make. It can be made right at your own home. It involves heating ammonium nitrate to a temperature between 170 degrees Celsius and 240 degrees Celsius in which it breaks down into nitrous oxide and water vapor. The formula is noted as “NH4NO3(s)-2H2O(g)+N2O(g)” (How To Make Nitrous Oxide). What you will need for this type of experiment is Ammonium nitrate, a Bunsen burner, nitrous oxide and water vapor, a test tube and test tube cap, a pipe, hot water, sheet metal with ½ inch hole, and a breaker with pure N2O. Another compound formed by this element is nitric oxide symbolized by NO. “…in air it forms nitrogen dioxide, NO2, a poisonous reddish brown gas.” (Encyclopedia2). Nitrogen trioxide symbolized by N2O3 is also a compound formed from Nitrogen as well as Nitrogen pentoxide, N2O5 which creates nitric acid when it is put in wat...

...ontact with water it creates an ammonia gas product. This compound is known to be a catalyst as well as being able to produce “tiny dark lumps” (Magnesium Nitride) that “could scratch a polished block of boron carbide, something only diamond was known to do.” (Magnesium Nitride). Potassium Nitrate or KNO3 is used mostly in the agriculture business to protect chloride free sources such as tobacco, potatoes, and lettuce from deterioration. This compound is also popular among pharmaceutical companies. ‘Its use being to help in the desensitization of sore teeth, and it is commonly used in many toothpaste products.’ (PNA) Sodium nitrate known as NaNO3 is a combination of sodium and nitrogen and is found in a powder like form. This substance is used every day in the use of pesticides and helps in getting rid of insects and pest that could be a threat to important crops.
This paper describes the methods used in the identification, investigation of properties, and synthesis of an unknown compound. The compound was identified as calcium nitrate by a variety of tests. When the compound was received, it was already known to be one of twelve possible ionic compounds. The flame test identified the presence of the calcium anion in the compound. The compound tested positive for the nitrate cation using the iron sulfate test. At this point it was hypothesized that the compound was calcium nitrate. Reactivity tests and quantitative analysis comparing the unknown compound with calcium nitrate supported this hypothesis. Synthesis reactions were then carried out and analyzed.
Ammonium nitrate, on its own, is relatively harmless in regards to explosives. Ammonium Nitrate is a secondary explosive; it requires a primary explosive for detonation. It is able to burn without detonating and can withstand shock in which primary explosives are unable to do When ammonium nitrate is mixed with fuel oil and detonated the results can be catastrophic. The Oklahoma City bombing of 1995 is evidence of the impact of a blast using ammonium nitrate and fuel oil, known as ANFO. Timothy McVeigh parked a van filled with ammonium nit...
The major sites for the production of ammonia are the intestines, liver, and kidneys. It is biosynthesized through normal amino acid metabolism. The kidneys generate ammonia from glutamine by the actions of renal glutaminase and glutamate dehydrogenase. Ammonia is formed from urea by the action of bacterial urease in the lumen of the intestine, which is absorbed from the intestine by the portal vein. Amines obtained from diet and monoamines that serve as neurotransmitters or hormones can create ammonia by action of amine oxidase. In purine and pyrimidine catabolism, amino groups attached to the rings are released as ammonia.
Acid rain has been proven to have damage forests, fresh waters and soils, killing insect and aquatic life-forms. It also causes damage to buildings and impacts on human health. Many people do not know what acid rain actually is. Acid rain is any form of precipitation that is unusually acidic, low pH levels, higher than normal amounts of sulfuric and nitric acid, occurs naturally and from man made sources. Forms when gases react in the atmosphere with water, oxygen, and other chemicals (what is acid rain?). The only water that will not have some amount of acidity is pure water. Pure water has a pH of 7 which is neutral; regular, unpolluted rain water has a pH of around 5.6. The acidity in rain water comes from the presence of Carbon Dioxide, Nitrogen Oxide, and Sulfur Dioxide. CO2 reacts with water to form carbonic acid. Nitrogen and water react during lightning storms, forming Nitric Oxide. NO is then oxidized to form N02. The NO2 reacts with water to form nitric acid. Due to this, the pH is lowered to be slightly acidic (Acid Rain). Acid rain can occur naturally in the environment, but the problem occurs when human interaction is the cause of the acidic levels.
The progression of humans was a long and lengthy process of advancement by which people originated from their hominin ancestors to intelligent beings. Humans were once merely defenseless and unable to hunt effectively until they discovered a new way of life. The breakthrough of the bipedal and industrial revolution changed the way humans got around and were able to become predators. Humans evolved from quadruped ape-like animals to one of the few animals that use bipedalism. Compared to animals, human language is more intricate and used all the time. In the documentary Project Nim, researcher Herbert Terrace and his team raised a chimpanzee and determined if the chimp could be subjected to developing subtle language skills. The documentary
nucleation. When nucleation in the liquid phase is catalyzed by foreign surfaces other than the material to be crystallized (such as by dust particles or wall surfaces), it is described as primary heterogeneous nucleation. In solutions in which crystals already exist, secondary nucleation is thought to be by far the most significant source of nuclei. The supersaturation at which secondary nucleation rises is much lower than that which gives rise to primary nucleation.( Garside and Davey ,1980; Garside, 1985; Nyvlt et al., 1985); Fig. (I.4) shown A simple scheme for nucleation .

The origin of the name "nickel" is a derivative from the German word "kupfernickel", meaning "Devil's Copper" or "St. Nicholas's Copper".The chemical properties of nickel are as follows: Nickel has the atomic number of twenty-eight. The atomic symbol of nickel, "Ni". It has the atomic weight (mass) of 58.70, to be exact, 58.693. It occurs in five stable isotopes. Physically, nickel is a lustrous silvery-white and takes on a hard polish.
Every chemical element or compound have specific properties that make them different than the other. However, these properties help us to understand every element or compound in which they can be used and how we can deal with them. These properties can be chemical properties which are defined as "that property must lead to a change in the substances ' chemical structure", such as heat of combustion and flammability ("Physical and Chemical…"). Also, these properties can be physical properties which are defined as the properties "that can be measured or observed without changing the chemical nature of the substance", such as mass, volume, boiling and freezing points ("Physical and Chemical…"). These two properties are related to each other. For
Nitrogen containing flame retardants release stable and inert compounds like nitrogen gases which stop the fire cycle by either interfering with the flammable gases or with the thermal degradation of the burning material. Nitrogen containing FRs can also enhance the performance of phosphorus FRs when
Dalton was the first person to develop a scientific atom theory, the ancient Greeks had ideas about the atom but could not prove it scientifically. Antoine Lavoisier and Dalton are responsible for the discovery of 90 natural elements. Dalton also explained the variations of water vapor in the atmosphere, the basis of meteorology. Dalton’s atomic theory says that each element contains its own number of atoms. Each element has its own size and weight.
NiSource is one of the biggest natural gas distribution companies in the USA. Company is not responsible for the production of natural gas, but rather purchases fossil fuel at the source and transmits supply thru its pipelines to industries and local costumers. Natural gas can be transported to distribution facilities in two ways: underground gas pipelines or shipped by the sea in LNG tankers. In nature during the extraction, natural gas exists as a gas, which needs to be captured by special pipeline system designed for gathering processes. Captured gas contains water and other impurities that have to be removed in production well. In order to be transported, it needs to be cooled and transformed into liquid, which increases transportation efficiency to processing units and improves transportation cost ratio. Regasification is the process when "wet", liquid natural gas is processed and changed to pipeline quality natural gas. Natural gas needs to be turned back to gas in order to be useful for residential and commercial customers. This process needs to be monitored and measured for quality and content of natural gas due to the risk of pipeline rupture and safety. "Natural gas entering the system that is not within certain specific gravities, pressures, Btu content range, or water content level will cause operational problems, pipeline deterioration, or even cause pipeline rupture."1 Natural gas transported to distributors is called "dry" gas due to the physical state.
These are some of the many properties reasons and qualifications for us using sodium in our everyday lives. These are the reasons why sodium is used all around the world to this very day and is also why we use so much of it. Ammonia has an important role in the formation of salt crystallizations which is why it is mentioned in the above paragraph and which so will be used in the experiment that is going to take place to test the importance of ammonia in salt crystallization and to see exactly how the ammonia is going to affect the salt in the end result.

The molecular formula of carbon dioxide is CO2. Carbon dioxide is a naturally produced nontoxic gas that has no smell. Carbon Dioxide is the most abundant greenhouse gas on the planet next to water vapor. In solid form it is commonly known as dry ice. It is a gas that is mandatory to the survival of most, if not all, living organisms on this planet. Terrestrial animals naturally create carbon dioxide in their lungs when the breathe out Humans alone do not physically or directly need carbon dioxide to survive though. Humans need carbon dioxide to survive because it feeds the plants which produce oxygen for us to breathe. Carbon dioxide in the atmosphere also allows for a warmer temperature so that conditions on Earth allow it to be inhabitable. Today we hear that carbon dioxide in the atmosphere is becoming a problem even though it is a naturally occurring gas. This is because humans have been interfering with the natural cycle of carbon dioxide.
