Introduction What is Valence Bond Theory? The valence bond theory describes the electrical structure of atoms and molecules. The concept explains how electrons are distributed among a molecule’s atomic orbitals. To better understand chemical bonding, the VBT incorporates quantum mechanical principles and explains the electrical makeup of molecules. According to this theory, all the potential […]
Introduction A mixture is formed by physical means constituting two or more types of components. A mixture is usually of two types: homogeneous and heterogeneous mixture. Heterogenous mixtures are non-uniform mixtures which do not have a single phase throughout. The word “homogeneous” has roots in Latin and Greek. The words homo and gene mean “same” […]
Introduction Various important materials in our daily life remain in a form of a mixture. So, for proper utilization of that element, we need to separate them. Depending on the nature of the materials, they are separated using a different procedure. There are different separation techniques like hand-picking, sieving, filtration, winnowing, and threshing, etc. In […]
Introduction Wool is a kind of fibre that is an important component in every living being’s life. It is obtained from various animals using specific extraction techniques, and it is then used for a variety of applications. Wool is that substance that gives protection to us in chilling weather conditions. It is used irrespective of country or […]
Introduction We need the purest form of metalloids like silicon, and germanium for the production of semiconductors. These metalloids behave like metals as well as non-metals whenever necessary. They are extensively used all over the world in all electronic gadgets and appliances. U.S. scientist W.G.P fann invented this technology in the 1950s with a motive […]
Introduction The valency of an element is indicated by its maximum capacity of making covalent bonds with any other element or the same element. Carbon has tetra valency since it can form a maximum of four bonds with another C atom or with other atoms like S, H, O, Cl, N, etc. Based on this, […]
Introduction The whole universe is composed of two parts; system and surroundings. There occurs an exchange of heat between the system and the surroundings. Thermodynamics tells us about the exchange of heat, different forms of energy, and the transformation of energy into work. It also explains some other properties of the system like temperature, pressure, […]
Introduction The shortest form of polymers is called monomers. Depending on their characteristics, preparation process, and many other factors, they are classified into two types- Natural and Synthetic polymers. The polymers which are generated naturally are called natural polymers, whereas polymers made by humans in some synthetic processes are called Synthetic polymers. There are different […]
Introduction Thermoplastics, polystyrene, and polyethylene can both be regularly moulded. It is therefore feasible to heat a foamed polystyrene cup while also moulding it into an irregular shape. For example, a dish. Individual molecules are separated from each other and move through one another in the polymeric material associated with thermoplastics. But even though the […]
