Introduction Phosphorus trichloride is considered a fuming liquid and the chemical formula of this element is $\mathrm{PCI_3}$. A colourless liquid is like transparent liquidity in terms of motile. This chemical element is mainly manufactured with the help of burning molten white phosphorus that is kelp in the contact with a strong base of nitrous acid. What is Phosphorus Trichloride? Phosphorus trichloride is mainly available in a liquid state and it can be poisonous as well as volatile in terms of atmosphere. The reactive power of this chemical agent is very high and it displays its explosive nature during the ... Read More

Introduction Phosphorus Pentachloride can be generated through an effective and common procedure of dry chlorine gas action on phosphorus trichloride. In the solid-state Phosphorus Pentachloride, remain as $\mathrm{PCl_4PCl_4^+ PCl_6PCl_6^-}$. The boiling point of Phosphorus Pentachloride is nearly 166.8°C and the melting point of Phosphorus Pentachloride is about 160.5°C. Phosphorus Pentachloride Phosphorus Pentachloride has a crystalline salt-like structure that gets dissociates partially in solution mainly in polar solvents like nitrobenzene. Phosphorus Pentachloride is determined as the solid having a pale greenish-yellow colour, which can be specified with the formula PCl5. The preparation methods of the Phosphorus pentachloride depict that the ... Read More

Introduction The mechanical properties of fluids are a branch of physics that states about the mechanics of the fluids, it includes the liquid, gas and the plasmas. Fluids are incompressible which means the density of the liquid is not dependent on the variation in the pressure and remains as constant. They also count as the most non-viscous. It means, that two liquid surfaces that came in contact are not pressing any kind of tangential force on one another. What is Fluid? In the field of chemistry, the term fluid can be referred to any liquid or ... Read More

Introduction Normally, the measurement of enthalpy and internal energy change is carried out by an experimental approach. This approach is known as calorimetry which is an important part of chemistry. It is mainly a technique which is developed on thermometric procedures. Here, a calorimeter is the vessel in which the procedure happens. In this part, the vessel is submerged in a known liquid volume. What is Enthalpy? Enthalpy is the heat energy and it is absorbed during a chemical reaction progression. In this part, enthalpy is represented by H and it indicates the energy amount. The change ... Read More

Introduction Materials accumulate for the composition of all the objects in the surroundings. The associated properties of the materials are different from one another. Most of the finished goods are made of up raw materials that have their unique traits which are mixed to make a final unit of product. The classification of the properties is done based on various physical as well as chemical properties. What is a Material? Materials are referred to as the building blocks of the finished products available in the market. The material in itself is a broad spectrum to discuss. The classification of the ... Read More

Introduction The mass spectrometers are mainly utilized in order to detect several unknown components through molecular weight and it also helps in the determination of phenomenon. This process also helps to quantify the already detected components and determine the structure and chemical properties of the molecules that are present in the given sample. The mass spectrometer generally performs through three major steps including Ionization Source, Ion Detection System, and Mass Analyzer. The two instruments that are utilized in various technical fields to study mass spectrometry is also determined as mass spectroscopy, are mass spectrometers and mass spectrographs. What is Mass ...

Introduction The molecular orbitals that help in the formation of the band seem to have the same energy as the atomic orbitals. This theory mainly describes the fact that electrons can jump from the valence band to the conduction band. This process happens when the temperature remains ordinary because it can help the solids to conduct electricity. The conductivity mainly depends upon the gap between the valence band and conduction band. Description of Metal Band Theory Band theory is considered a concept that focuses on the matter of solids. This theory is also known as zone theory and it shows ... Read More

Introduction The manufacturing process of different types of lightweight and flexible items is improved from before after considering the application of polystyrene. Styrene is the most effective monomer of polystyrene. Another term associated with polystyrene is ethyl benzene. Phenyl ethane and vinyl benzene are two other components in which all integrated precursors are included. Definition: Polystyrene Polystyrene is an important stiff, transparent and hard resin and is produced by the polymerization of styrene. At room temperature, a thermostatic polymer is found in a solid form. At the time of heating the component at a high temperature, polystyrene started ... Read More

Introduction One of the most important types of carbohydrates is polysaccharides in which starch, cellulose, glycogen and some more elements are included. Polysaccharides are key structural components of a plant cell. Different types of monosaccharide are important in developing different polysaccharides. Each polysaccharide possesses an immense significance that is helpful in maintaining the source of energy. Definition: Polysaccharides Complex carbohydrates are commonly known as polysaccharides that are formed with a chain of monosaccharide. The chains are attached with a bond and these chains are glycoside. There are two main fundamental types of polysaccharides, namely, heteropolysaccharides and homopolysaccharides.Starch is considered one ... Read More

Introduction Polypropylene is generally produced through a reaction of chain-growth polymerization that involves propylene. The polymer can also be known as a type of polypropylene and sometimes it is represented with the abbreviation form of ‘PP’. This type of polymer is called thermoplastic polymer, and it guides to soften by heating and can be remoulded. Definition: Polypropylene Polypropylene is a particular form of polypropylene and it is used for different ranges of purposes. It is mainly made from monomer propylene through a particular process. This type of plastic refers to the thermoplastic that is crystalline in form and it ... Read More
