Introduction A type of missile defence system called an Anti-ballistic missile (ABM) is intended to intercept and destroy approaching ballistic missiles. While ABMs are thought to have substantial consequences for both national security and international affairs, their development and deployment have been a source of strategic intrigue and debate ...

Introduction Types of solutions are varied with the variation of the dissolved substances as well as combination with solvent. It results in blending a solid or a liquid compound within another solid or liquid or gas. Solutions refer to a part of daily life because these exist in each common ... Read More

Introduction Unsaturated solutions are in need of more concentrations of solute molecules into the solution. There are different types of solvents that are able to break down a solute and shows significantly different physical properties than its original one. Once all the properties of the solute are assimilated into the ... Read More

Introduction Unit cell of packing efficiency is referred to the development of the particles of constituents of any specific structure or cell with the presence of void spaces between the atoms. The matter of packing cells is obtained with any specific volume that occupied by the particles that are constituent ... Read More

Introduction Unsaturated hydrocarbons are made up of multiple covalent bonds between one or more than one C-C bonds in a single compound. The field of organic chemistry is usually common to have multiple covalent bonds reside between carbon atoms. In IUPAC nomenclature, the numbering is counted from the side where ... Read More

Introduction Uncertainty in measurement may often occur in different experimental and theoretical calculations. Numbers are used conveniently to focus on the possible results in experiments with some amount of uncertainty. The impact of uncertainty in different types of measurements has been defined as a parameter that is associated with the ... Read More

Introduction Titration is a quantitative analysis used in chemistry used to identify the strength or concentration of a given unknown chemical solution by analysing it with a known solution concentration with the presence of an indicator. Both oxidation and reduction happen at the same time. Titration is a process ... Read More

Introduction Ununoctium is the temporarily given IUPAC name which helps to identify the chemical element. Scientists know very little about it; however, it is considered as super heavy element with an atomic number of 118. The atomic number and atomic mass of the discovered element is the highest. What is ... Read More

Introduction Different types of reactions experiment may be seen in the particles when these are passing through chemical reactions. Internal as well as external changes can happen in this reaction or experiment. In these types of reactions, the primary substances does not exerts with any changes in physical properties like, ...

Introduction Ullmann reaction is a coupling reaction between aryl halide molecules. Fritz Ullmann was a German chemist who first noticed this type of reaction and this reaction is called the Ullmann reaction after his name. Copper plays an important role throughout the entire coupling mechanism. Meaning of Ullmann Reaction Ullmann ... Read More
