Threshold inhibitors are the name that refers to the chemical agents that inhibit scale and work at quantities below the stoichiometric level. These inhibitors foil the whole process of precipitation. Various mechanisms take place when interfering with the process of precipitation. The first manner is the modifying of the crystals into shapes that make it impossible for attachment with other crystals. Secondly, the inhibitors attack the forces that bind the particles into precipitation to break the bond necessary for the precipitation. The third mechanism is through impeding the growth of the particles to bring a non-precipitation zone. Despite the effectiveness of the antiscalants, other indispensable factors determine the whole process. These factors comprise of presence of other ions in the solution, the temperature, the PH and the ratio of super saturation. Moreover, the heaviness of a polymer matters a lot when the antiscalant is polymer (Singh et. al., 2008). CACO3 crystallization is a process that is intricate and requires great understanding to know the reaction that takes place with the antiscalant. The various mechanisms with which the antiscalant inhibits the precipitation are under one method of “charges attraction”. The antiscalant is always negatively charged and it gets attracted to the area with the crystals, which is positively charged. The definition of threshold inhibition is assumed from this description. Threshold inhibition thus refers to the fusing of the particles of the inhibitor to the crystal-filled arena that is rich with ions. The surface of the crystallization zone tends to be loose and hence creates a space for absorption of the inhibitor’s particles. Once the inhibitors have penetrated to the inside of the crystals, the formation of crystals is in interference. It delays the beginning of crystallization since the walls that would bind the crystals are filled with the inhibitors particles. The first crystals cannot be detected since the inhibitors particles impose a derailment between the period of super saturation state and crystallization (Singh et. al., 2008). Consequently, the crystals form but the inhibitors attack to tamper the growth sites. It thus obstructs the normal reaction that would have to happen. The inhibitors modify and alter the growth of the crystals. Results from the modification of the crystals, is retarded crystals that do not have the strength to stick on metal materials. These crystals are then electrostatic charged and thus posses repulsion with particles with the same side charges. It makes the crystals not to converge and clot (Singh et. al., 2008). There is a common fact that phosphonates are better threshold inhibitors than polycarboxylates. Contrarily, polycarboxylates are better dispersants than phosphonates. Both chemical agents show their reaction when in a solution in inhibiting scale threshold. In a condition where the level of super saturation is low, the phosphonates can be the ultimate solution. Conversely, where the level of super saturation is high, polycarboxylates can salvage the reaction (Singh et. al., 2008). Polycarboxylates have properties that can help in dispersing of particles that are useful in a condition of high super saturation. It is a ...Download file to see next pagesRead More

This would include the attraction between positive and negative ions in a crystal of an ionic compound, the covalent bonds in a molecular substance as well as the covalent bonds linking atoms in a network structure, such as that of carbon (diamond).Metallic bonds are also classified as intramolecular forces (Frederick, 1979, P.63)Intermolecular forces operate between, rather than within, the molecules of a covalent substance. This would include the attractions exerted by one molecule of a molecular substance on another, such as the force of attraction between water molecules in ice ,the attractions between atoms... relative...

...x100 = 65.62%. 137x27 Question – 3 a. In 1870, Markonikov laid down a basic principle of chemistry that holds till today. The Markonikov Rule states that when a hydrogen halide (Hydrochloric acid, HCl being an example) reacts with an asymmetrically substituted alkene the hydrogen attaches itself to the carbon atom that has the larger number of its hydrogen atoms substituted. The halogen automatically attaches itself to the carbon atom having the least number of its hydrogens substituted. An example of such an addition reaction: Cl2HC=CH2Cl + HCl  Cl2H 2 C=CH2Cl2 Here the halide chlorine attached to the right hand side of the molecule that had fewer hydrogen atoms replaced. b.

While itwas first detected as early as the 16th century, it wasn’t until nearly two-hundred years later that it was rediscovered and given its chemical name. Hydrogen combines to form a countless number of compounds that position it as a cornerstone to life in the universe. It is an essential element in things as essential as water, as small as healing cuts and bruises, and as large and industrial as oil refinement. This essay examines the historical background of hydrogen, its chemical formula and elements, as well as its use in compounds that make up the fabric of our very existence... Introduction...

This is due to reduced opposite charge potential between them that increase attraction. In C-N, C is partially negative while N is partially positive in charge because one electron is unbounded in C. Fe cations bond on the C side forming negative C-center hence the force of attraction is now distributed for both Fe and N.

... Introduction to Chemistry: Analysis of Oxygen (O2) Introduction Oxygen is a chemical element that largely forms part of the atmospheric and is widely recognized with the sustenance of life and survival of organisms. It has a formula of O­2. As a chemical element, this substance has an atomic number of 8 and belongs to the chalcogen group on the periodic table; thus, making it build and possess certain significant characteristics for its operations such as being a highly reactive non-metallic element. Subsequently, oxygen is widely used as an oxidizing agent through its readiness to form compounds (in most cases oxides), with most of the atmospheric elements (Bauer, Birk & Pamela 145-149). Identification by mass sets this element... in...
