free group dynamics

This is derived from the Greek word 'dynamis', meaning power. Dynamics involves the study of the cause of motion, which is force. When we relate motion of an object to the forces associated with it and to the properties of the moving objects, we are dealing with dynamics. In th..

Equilibrium and its Dynamic Nature - The state of reversible reaction at which the concentrations of reactants and products do not change with time is called a state of chemical equilibrium. This state can be recognized by the constancy of certain measurable properties such as pressure, d..

The state of reversible reaction at which the concentrations of reactants and products do not change with time is called a state of chemical equilibrium. This state can be recognized by the constancy of certain measurable properties such as pressure, density, colour, concentration, etc. At eq..

The state of equilibrium is a state in which the measurable properties of the system do not undergo any noticeable change under a particular set of conditions. We have seen that all observable properties of a system become constant at equilibrium. It may lead us to think that the reaction stops a..

The vertical column in the periodic table is called as group. There are 18 groups in the long form of the periodic table and they are numbered from 1 to 18 in the IUPAC system. In the old system of naming they are numbered as I to VIII with A and B groups. This conven..

The measurable/visible properties of the system must remain unchanged with time. Once, an equilibrium is reached the properties of the system do not change with time. When equilibrium is attained, there exists an expression of concentrations of the substances involved in equilibrium, which bec..

Which group has more? => buses or bicycles or cars or planes..

On moving down the group the number of valence electrons remain the same and therefore all the elements in the group exhibit the same valenc..

Aromatic hydrocarbons are called arenes. When one or more hydrogens are removed from the aromatic hydrocarbons, the residues left behind are termed as aryl groups (similar to alkyl groups in the case of aliphatic hydrocarbons). The aryl groups are represented by Ar. S..

Functional Groups - When an atom or group of atoms bonded to a carbon atom in the chain or ring of an organic compound, shown some characteristic properties of their own, they are termed as a functional group. Thus, a functional group is an atom or group..
