An electron has kinetic energy 2.8 x 10 -23 J . de-Broglie wavelength will be nearly: (me: 9.1 x 10 -31 kg) (1) 9.28x 10 -4 m (2) 9.28 x10 -7 m
50ml of 0.1M NH 4 OH ,25ml NH 4 Cl weere used to make a buffer . what is the PH is if Pk b is 4.8? Solution) The given buffer is a base buffer [NH4OH] =[(50*0.1)/75] [NH4Cl] =[(
Definitions A Br ø nsted base a proton acceptor, and Br ø nsted acid is a proton donor. In this definition an acid-base reaction accepts protolysis:
Since fluorine is very electronegative as a result hydrogen develop a very positive character. As a result the H-bonding is very tough because of large difference in electronega
