The uncertainty in momentum of an electron is 1 x10 -5 kg- m/s . The uncertainty in its position will be (h= 6.62 x 10 -34 kg - m 2 / s): (1) 1.05 x 10- 28 m
Physical charterstics of monocarboxylic acids Physical state: The first or initial three members (upto 3 carbon atoms) are colourless, pungent smelling liquids.
The bond energy of an O- H bond is 109 kcal mol 1. When a mole of water is formed from H and O atoms, then 218 kcal is released. Two O-H bonds are there is H2O so 2*109 kcal an
