Introduction The determination of nitrogen content or determining protein content in samples such as food was a major issue some years ago. The method that already existed some years ago was not so accurate. That is a proper method was not discovered at that time. Later the Danish chemist Johan ... Read More

Introduction Krypton is an element present along with the noble gases in the periodic table with the symbol Kr. It is an important element in the p block with the atomic number 36. The discovery of elements continued to be very important in chemistry. The extraction of argon gas ... Read More

Introduction Natural gas would be a naturally occurring substance composed largely of methane, with negligible concentrations of various higher alkanes and, in exceptional cases, CO2, N2, H2 S, as well as He. Deep under the earth's crust, with additional solid-liquid hydrocarbon resources such as coal as well as crude oil, ... Read More

Introduction It is readily possible to find air, which is a gift of nature. It is a crucial component of nature that renders life on earth conceivable. Atmospheric pressure is established by the heaviness of the air. The percentages of the several gases that make up air are as follows: ... Read More

Introduction The matter is everything that surrounds us and engrosses space. It has different properties. These properties are defined as intensive and extensive properties of matter, in 1917 these terms were first used by the scientist Richard C. Tolman. Intensive properties do not depend upon the quantity of matter. Extensive ... Read More

Introduction The intermolecular force would be the strong force that exists between surrounding atoms. Thermal energy is the total of all molecules' and particles' kinetic energy. The intermolecular forces of attraction could be also known as Vander Waals forces. Whenever atoms, molecules, as well as ions are close. In contrast, ... Read More

Introduction S and p-block together are called the main group elements of the periodic table. And is the reason that this block constitutes a majority of elements in the periodic table. The discovery of many elements by scientists leads to the classification of elements properly and sequentially. Which further resulted ... Read More

Introduction Clothing is always a needy thing for humans. Animal skin was used by ancient people for the making of clothes. Progress made by humans leads to the development of a variety of fabrics to make clothes. Discoveries made by humans lead to the development of synthetic fibres that we ... Read More

Introduction A member of the organic halogen compounds, iodoform is an organic iodine molecule with the chemical formula CHI3. It is a volatile, crystalline material that is a light-yellow colour. It smells similar to chloroform and has a pungent, recognisable scent that is sweet-smelling. What is Iodoform? The class ... Read More

Introduction Ionization energy (I.E.) is described as the minimum (min) required energy (e) to remove (throw out) the most loosely (weakly) bounded electron (e) of an isolated gaseous (g) atom, +ve ion, or molecule. Ionization energy (I.E) follows periodicity in the modern periodic table. The normal or general trend ... Read More
