Introduction Chemical reactions for CBSE class 12 students are very interesting part of study. Itcan be seen everywhere in the daily human lives. It commonly happens when two or more compounds are changed into one or more substances due to the reaction between them. When the chemical reactions produce the substances of chemical compounds or chemical components. In simple words, when the rearrangements are done within the constituent of atoms, the process is commonly called a chemical reaction. Definition of Chemical Reaction Chemical reactions are scientific phenomena happen everywhere all around the world. Starting from the metabolism of ... Read More

Introduction Types of electrophoresis are classification of the processes involves during application of electrical energy to any substance. Electrophoresis is derived from two Greek words, elektron means amber and phoresis means the act of bearing. In 1931, the first work of electrophoresis begins by Arne Tiselius. It was a primitively easy of separating the chemical and molecules analysis. The modern version of this process starts in the 21st century. What is Electrophoresis? Electrophoresis is a method and technique used for separating the RNA, DNA, and protein molecules. The whole process is done on the basis of size of the ... Read More

Introduction Types of Fabric play a crucial role in society, as it provides numerous numbers of benefits to society. This acts as a vital component as the raw material used in the production or manufacturing of garments for all the civilians present within the society. The quality of fabrics tends to influence the quality of the materials used in making the garments. The quality of the garments also changes in the aspects of texture, and smoothness. Fabrics are widely used for a massive range of production purposes. Defining Fabrics Humans come across various kinds of fabrics on a daily ... Read More

Introduction Ununseptium is an artificially created element found in the periodic table and the chemical name of this element is Tennessine symbolised as Ts. It was first invented in the year of 2010 in a Russian laboratory. In the periodic table, it is placed in the group of p-block elements and group number is 7. Therefore, it is classified as a halogen. Ununseptium is solid at room temperature. It has four isotopes such as: $\mathrm{^{291}Ts, \: ^{292}Ts, \:^{293}Ts, }$ and $\mathrm{^{294}Ts}$. What is Ununseptium? Ununseptium is a recently discovered component that is placed in 117 in the periodic table. It ... Read More

Introduction Urea is formed at the time of producing amino acid from dietary proteins. The chemical structure of the element is $\mathrm{CH_4N_2O}$ and another name of this element is Carbamide. The component is one of waste elements of living organism having no physical impact. The procedure of detecting the urea level helps to find the problems of kidneys in the body. The compound also has some commercial and agricultural values. The compound is used as fertilizer in the agricultural sector besides ammonia. What is Urea? Urea is a diamide state of carbonic acid and the chemical formula is $\mathrm{CH_4N_2O}$. The ... Read More

Introduction Uses and applications of the noble gases are very important aspect of chemistry to understand the contribution of these elements in our daily life. Noble gases behave like pure non-metallic compounds, as these are colourless and odourless gases with low melting and boiling points. In the liquid form, these elements are not good conductors of electricity. The condition for noble gases to exist in their gaseous form is at standard temperature and pressure. The general configuration of the noble gases is considered as $\mathrm{ns^2np^6}$. The noble gases generally have a very stable electronic configuration that helps them to ... Read More

Introduction Uranium was first isolated by the French chemist Eugène-Melchior Péligot, in the year 1841. This element was broadly used during the nineteenth century for various purposes like giving the glass a greenish-yellow hue which is also known as vaseline glass. In 1896, scientist Henri Becquerel first discovered its radioactive qualities. This discovery was further researched by Enrico Fermi in 1934. This research helped to discover the nuclear fission caused by uranium isotope U-235. What is Uranium? Figure 1: Atomic structure of Uranium Pumbaa (original work by Greg Robson), Electron shell 092 Uranium, CC BY-SA ... Read More

Introduction Carboxylic acids are prepared when the chloride of acid is hydrolyzed with a water base. This chloride is acid when reacted with the base they produce carboxylic acid, which can be acidified again through laboratory processes. On hydroxylation of acid anhydrides, R-COOH is formed artificially. Carboxylic acids are generally made up of 2 electronegative oxygen atoms that make the molecules of the acid polar. What is a Carboxylic Acid? The organic compound that has a carboxyl functional group is referred to as carboxylic acid. These compounds can be freely found in the environment and can be synthesised artificially ... Read More

Introduction Uses of Iron, copper, aluminium, zinc, and many more are very important for our daily life usages as well as in industrial scale. Earth's crust is composed of several minerals and some of the metals and its ores are determined as the major resources for humanity. Metals such as Iron, Copper, Aluminium, and Zinc are inorganic compounds that are found below the earth’s surface and are easily identified by evaluating their properties. These metals can be identified through their properties like hardness, toughness, ductility, malleability, elasticity, tensile strength, brittleness, and compressive strength. What are p-block and ... Read More
