The standard enthalpies of reaction can be calculated using Hess’s law, by finding the difference between standard enthalpies of products and... View Article
LiCl is more covalent than CsCl since the size of the anion in Lithium chloride is bigger than in Caesium chloride (as per Fajan’s rule). Or... View Article
The noble gases are also called inert gases sometimes as they are monoatomic and chemically inert under normal conditions. These gases are... View Article
V3+ (Vanadium 3+ ion) is paramagnetic since it has two unpaired electrons and therefore, it can get easily magnetised in presence of the external... View Article
Solids are rigid bodies that have fixed shapes and volumes. The particles of solids cannot move about their position, since the force of... View Article

Lanthanides do not have the tendency to form oxo-cations, but many actinides form oxo-cations. Since actinides have greeted tendency to form a... View Article
Enzymes work as catalysts that increase the speed of reaction by weakening the substrate bonds and hence reducing the overall activation energy.... View Article
The periodic motion of a pendulum or the to and fro motion is called its oscillation. The center of oscillation is known as the equilibrium... View Article
Sound waves are longitudinal and not transverse because the particles travel parallel to the movement of energy. Learn more here: Difference... View Article
LiCl is more covalent than LiF because the size of the anion in Lithium Chloride is bigger than cation (as per Fajan’s rule). Hence, the covalent... View Article
Maltose which is otherwise called malt is a disaccharide composed of two alpha D glucose units. The two-unit of glucose are connected with an... View Article
FeCl3, Iron Chloride, is a good Lewis acid. Therefore, when benzene reacts with halogens in the presence of FeCl3, aryl halides are formed. This... View Article
When diborane (B2H6) reacts with lewis base (electron-pair donor), it results in Borane adduct. Suppose if diborane is reacted with ammonia,... View Article
