Quantum Theory of Covalent Bond - Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence b..

Introduction - Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mechanisms in plants helps u..

The solar spectrum of electromagnetic waves include energy packed heat generating waves called radiation waves. As they lie beyond red colour waves of visible spectrum, they are also called 'infra-red rays'. These infrared rays lie in the wave length range of 700-900 mm. Two types of infrared rays ..

Neils Bohr was a eminent Danish Physicist who obtained his doctorate in theoretical Physics in 1911. He made a great contribution towards the understanding of atomic structure and quantum mechanics. He was awarded the Nobel Prize in Physics at the young age of 37, in 1..

The study of transport mechanisms in plants helps us to understand the uptake of the various types of substances and their passage through the plant..

The study of reactions is one of the important areas of Chemistry. There are many aspects of a reaction like the rate of reaction, energy absorbed or evolved, mechanism of a reaction that can be evaluated only with weight and volume relationships. A study of reactions is possible by ..

Food chain studies help, a) understanding the feeding relationships and the interaction between organisms in any ecosystem. b) comprehend the energy flow mechanism and matter circulation in ecosystems. c) understand the movement of toxic substances and the problem of '..

states that one quantum is absorbed by the molecule responsible for the primary photochemical process. After absorption, the excited molecule can then undergo various reactions. It can form a product, it can catalyze a chain reaction, or it can get de-excited. If on absorption of one ph..
