. Elements with similar properties occupy similar positions when their properties are plotted as a function of their atomic weights was Lother Meyer's arrangement. All the above attempts were very elementary and could not be successfully applied to all the elements, which at present are a..

Measurements - Everything that we use in our daily life is ultimately governed by principles of physics. All gadgets we use everyday at home, bicycles and cars, all different types of machinery and instruments, work on principles of physics. Hence to understand even the elementary working..

Mitochondria are tiny structures that occur in varying shapes cylindrical, spherical, oval, rod shaped etc. They are found distributed all over the cytoplasm. fig. 16.6 - Mitochondria Each mitochondrion is bound by a double membrane. The outer membrane is smooth and straight, while the inner membra..

(i) Skeletal equation (ii) Elementary gas in atomic form (iii) Starting with KMnO 4 : K and Mn are balanced (iv) Balancing O atoms (v) Balancing H atoms (vi) Balancing Cl atoms The equation is now balanced in the atomic form. (vii) To make it molecular..

Elementary reactions are classified according to their molecularity. The number of reacting species, which are involved in simultaneous collision to bring about a chemical reaction is called the molecularity of the reaction. In a unimolecular reaction, a single molecule shakes itself apar..

Limits- operations on functions Continuity of a function Intermediate value, extreme value theorem Derivatives, differentiability Derivatives of functions Chain rule Rolle's theorem, mean value theorem, and L'Hopital's rule Maxima, minima, inflection points, intervals Newton's method (app..

Molecularity - Elementary reactions are classified according to their molecularity. The number of reacting species, which are involved in simultaneous collision to bring about a chemical reaction is called the molecularity of the reaction. In a unimolecular reaction, a single molecule sha..

Series Reactions (First Order) - A complex reaction involving two series reactions can be of the type, A reacts to give B, which is then transformed to C. Both the elementary reactions (1) and (2) exhibit first - order kinetics, that is, For this reaction, [A] = [A] o exp (-k 1 t) (36) It..

Avogadro's number is the number of elementary units (atoms, molecules, or ions) present in one mole of a substance, and it is equal to 6.023 x 10 2 3 . The concept of a mole being equal to a number 6.023 x 10 2 3 is akin to the concept of a dozen being equal to a number 12. A mole of ..

Specific Heat - Two objects made of the same material, say marble, would have heat capacities proportional to their masses. It is therefore convenient to define a heat capacity per unit mass or specific heat that refers not to an object but to a unit mass of the material of the object. Equation (i)..
