bridging terminal

So, three of the hybrid orbitals are singly occupied, while the fourth hybrid orbital remains vacant. The two half-filled hybrid orbitals of each B atom overlap with two '1s' orbitals of two 'H' atoms, giving rise to in all four B - H regular covalent bonds. Each boron atom is left with one half-f..

fig 5.9 Salt bridge is an inverted U-tube filled with a strong electrolyte like KCl in Agar-Agar gel. Anode (Negative terminal) is Zn (Oxidation takes place). Cathode (positive terminal) is Cu ( Reduction takes place..

Current through a given area of a conductor is the net charge passing per unit time through the area. To maintain a steady current, we must have a closed circuit in which an external agency moves electric charge from lower to higher potential energy. The work done per unit charge by the source..

This instrument is identical to the meter bridge except that in this case, the resistance wire is of more than a meter length. This enables greater accuracy. A standard cell of emf e 1 maintains a constant current throughout the wire. As the wire is of uniform material and cross secti..
