In an electrochemical cell a redox reaction perform in two halves. Electrons are liberated by the oxidation half reaction at one electrode and go through an electrical circuit to another electrode where they are used for the reduction. The cell potential E is the potential difference between the two electrodes have to balance the thermodynamic tendency for reaction, so that the cell is in equilibrium and no electrical current flows. E is related to the molar Gibbs free energy change in the overall reaction according to
where n the number of moles of electrons passed per mole of reaction and F is the Faraday constant (9.6485×104 C mol-1).
The orbital angular momentum of an electron in 2s -orbital is: (1) 1/2 h/ 2Π (2) h/ 2Π (3) √2 h/ 2 Π (4) Zero Ans

how can we calculate it?
A flash separator "flashes" (abrupt increase in temperature and pressure) a liquid stream containing multiple species. Not all of the liquid vaporizes, but the vapor that does form
Isomers, which vary in the orientation of groups around the double bounded carbon atoms, are known as geometrical Isomers. It is also known as Cis-Trans Isomerism.
Physical Properties - Alkenes (i) Alkenes are odourless and colourless. (ii) Alkenes are soluble in organic solvents and insoluble in water. (iii) Physical state of Alken

Compute the percent ionic character of the interatomic bonds for the following compound: TiO2.
This is an acid-catalyzed addition to the double bond much like hydration, except that an alcohol rather than water is the nucleophile that reacts with the carbocation intermediate
