Nitrogen

the six delocalized electrons. Nitrogen is ideal so we can imagine replacing a CH group in benzene with a nitrogen atom. The orbitals in the ring have not changed in position or shape and we still have the six electrons from the three double bonds. One obvious difference is that nitrogen is trivalent and thus there is no NH bond. Instead, a lone pair of electrons occupies the space of the C–H bond in benzene.…

In ecology, interspecific competition occurs between two different species that compete for the same resources (Connell, 1983). These resources include sunlight, water, nutrients, space and mates (Connell, 1983). Interspecific competition can lead to reduced fitness of one or both of the species, as resources of the ecosystem become limited (Connell, 1983). In this study, the effects of interspecific competition were compared between Cynodon dactylon (Bermuda grass) and Calyptocarpus vialis…

of the earliest items to be referred as a fire chemical component. The gun powder components are known to be all reactive products which cause the reaction of an explosion. Nitro compounds are highly reactant and is stabled by a molecule which is nitrogen. The molecules which nitro compounds obtain do not bond together which makes the nitro compound explosive since there is no boding whatsoever. When nitro compounds were used they were specifically made for gunnery in wars. If nitro compounds…

The aim of this experiment was to determine the percentage composition of magnesium and oxygen in magnesium oxide and evaluate if the composition varies or remains constant. To test this, magnesium was heated and made to react with the oxygen gas in the atmosphere. This reaction formed the ionic compound, magnesium oxide. The percentage composition was later calculated based on the results of the experiment as shown in the above calculations, Figure 4. These results were compared to the expected…

4.1.1 Particulate control. Particulate can be defined or referred to as tiny particles of matter like dust, smoke, soot which are being emitted during agricultural and industrial processes as well as other economic activities. Various methods involved with particulate control operate basic principles. Solid particulate particles are usually isolated from gases where they are controlled by physical procedures like through a settling chamber. Settling chamber is a wide and elongated pipe where…

Raw material: Two sweet varieties of Apricot (Prunus Armeniaca L.) namely Marghulam and Halman fully ripened fruits were collected from Gilgit Baltistan region in Northern Areas of Pakistan. Apricots were sun dried under open condition (26-34+4 C, RH 41-52%) for 16-19 days. The sun dried Apricots were packed in polyethylene bags containing 01Kg of dried fruit. Further The dried samples obtained were ground to a fine powder and stored at 5°C in air-tight containers prior to further analysis.…

Known for the method used in industry to synthesize ammonia from nitrogen and hydrogen gases, Fritz Haber was, and still is, a well-known German chemist whose invention is used today for the production of fertilizers, cleaning products, and explosives. He was born on December 9, 1868, in Breslau, Prussia. Three weeks after being born, his mother passed away due to the toll her pregnancy took on her, thus leaving him to be raised in a Jewish household by his father, Siegfried, and several of his…

The emergence of cytochrome oxidase is considered to be a very important event in evolutionary history. However, not much is known on the development and emergence of this enzyme. Molecular data demonstrates how cytochrome oxidase emerged before the divergence of archaea and bacteria, and well before the great oxidation event. This paper proposes a research plan to investigate the origins of cytochrome oxidase. Background Throughout the three domains of life, a variety of metabolisms are present…

English chemist.(It’s Elemental- The Element Argon) These two chemists weren’t actually trying to discover this element. Stated at Argon- Element information, properties and uses | Periodic Table, they actually were trying to explain the density of nitrogen from air differed from that obtained by the decomposition of ammonia. It just so happened while they were trying to explain their theory they were able to discover the element Argon. Argon can be found in nature in a very little amount.…

The water quality of the U-High Creek has been tested to be excellent. However, that does not mean that every creek is pure or excellent. Some people, more specifically farmers, use fertilizers made from Nitrogen and Phosphorus to kill pests or bugs. Little do they know, the pesticide or fertilizers get into streams and creeks and contaminate it leaving algae growing more rapidly or consistently. Consequently, if the algae overfills the creek, organisms will then die out from oxygen shortage…
