GEOCHEMISTRY
The chemical processes taking place in the crust are especially important as they have build ores, concentrated mineral deposits that are exploited industrially as sources of specific components and their elements. Summarizes the principal chemical forms in which each element perform. At least half the elements prepare in the crust as oxides (mostly complex ones such as silicates) or less commonly as halides, and are called lithophiles. All the bigger electropositive metals are in this class. Chalcophiles are components present in sulfide minerals; these include some elements chemically same to sulfur (As, Se) together with less electropositive metals of the later post transition and transition metal groups.

Nitrogenous base: These are heterocyclic organic compound that comprise two or more nitrogen atoms in ring skeleton. These are called bases as the lone pairs of electrons on th
Q. General Characteristics of elements of Group 13? All the elements of Group 13 have similar valence shell electronic configuration of ns 2 np 1 , but the underlying core vari
Q. Explain scale formation and sludge formation in boilers. How are they formed? Ans Boilers are used for steam generation. When hard water is evaporated, progressively
Q. Extraction of Aluminium? Aluminium cannot be extirpated economically from the silicate minerals. Therefore bauxite is the most important ore for the extraction of alumimum,
When the azimuthal quantum number has a value of l= l , the shape of the orbital is : (1) Unsymmetrical (2) Spherically symmetrical (3) Dumb-bell (4)Complicated Ans:
The formation of a co-ordination compound involves reaction between a metal ion and ligands. If the force of attraction of the metal ion with ligands is strong a stable complex may
