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).
How many ion H2- does have The H2- ion having three electrons. This can be conceived as the combination of a hydrogen atom with a hydride ion (H-). By the aufbau principle, two

Acetic Acid or Ethanoic Acid Acetic acid is the oldest termed as fatty acid. It is the major constituent of vinegar and therefore its name (Latin acetum = vinegar)
Why a covalent bond is directional? Covalent bond is formed as a result of pairing of two electrons in atomic orbitals of two atoms. Bond then must lie along the direction of
