Define the Elements of a galvanic cell?
We will treat a galvanic cell as a system. The cell has two metal wires called terminals that pass through the system boundary. Within the cell are phases that can conduct an electric current and are collectively called electrical conductors. Each terminal is attached to an electron conductor that is usually a metal, but might also be graphite or a semiconductor.
Figure: A galvanic cell without liquid junction.
Each electron conductor is in contact with an ionic conductor, usually an electrolyte solution, through which ions but not electrons can move. Both of the electron conductors can be in contact with the same ionic conductor; or they can be in contact with separate ionic conductors, in which case the ionic conductors contact one another at a liquid junction.

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,
p-orbitals of an atom in presence of magnetic field are: (1) Two fold degenerate (2) Non degenerate (3) Three fold degenerate (4) None of these Ans: Non degenerate
The angle among the lines joining the nuclei of the bonded atom with a central atom is known as bond angle.
Assume a cell possesses 1000 genes, but at any point in time, ten percent are being used (i.e., "expressed"). If a typical protein has 100 amino acids, what is the total number of
Deodorants: Just as the name suggests, deodorants are applied basically to mask the body odour. The body odour provides from the bacterial action subsequent perspiration. Hence
Synthetic Detergents - Oils and Fats The synthetic Syndets or detergents are substitutes of soaps. They comprise cleansing power as good or better as compared to ordinary soaps
Merits of atomic fluorescence spectrometry technique: The merit of the AFS methods lies within the greater sensitivity achievable because of low background and interference.
Strategy 2 The wheat flour amount is fixed at 3940g, but that of the active ingredients is varied from 30 to 60 g with the ratio of A : B : C fixed at 3:2:1. The combinations
