which element have highest oxidation number and why?
If hydrogen atom is in an energy level represented by n=4,how many spectral lines are possible in its emission spectrum? Ans) There is a formula for this i.e [ (n 2- n 1 +1)
The frequency of radiation emitted when the electron falls from n= 4 to n=1 in a hydrogen atom will be (Given ionization energy of H = 2.18x 10 -18 J atom-1 and h= 6.625x 10-
scientist''s explain about atomic
basic principle of electrogravimetry
The first ionization potentials for Na, K, and Rb are 5.138, 4.341, and 4.166 eV, respectively. Assume that the energy level of the outer electron can be represented by a hydrogenl
I think you are talking about aniline(Nitrogen containing compounds) . If so then no, they do not undergo friedel craft as nitrogen donates its lone pair to form a complex and do
54) Note: This problem is worth double credit.It is desired to concentrate a caustic soda solution from 12.5 to 40.0% in a double-effect evaporator. Feed solution at a flow rate of
