I G ev = x eV, where x is

What is drift velocity of free electrons ? Deduce I = n A eV_(d) where the symbols have their usual meaning.

An element undergoes a reaction as shown : X+e^(-) to X^(-) Energy released =30.876 eV The energy released, is used to dissociate 8 g of H_2 molecules equality into H^+ and H^* , where H^* is in an excited state, in which the electron travels a path length equal to four times its debroglie wavelength. (a)Determine the least amount (moles) of 'X' that would be required. Given : I.E. of H =13.6eV/atom Bond energy of H_2 =4.526 eV/molecule.

M_((g)) rarr M_((g))^(+) +e^(-), DeltaH = 100eV M_((g)) rarr M_((g))^(2+) +2e^(-), DeltaH = 250 eV which is incorrect statement?

The range of f(x)=[tan x] is where [.] is a G.I.F

A^(+)(g) rarr A(g) DeltaH =- 2eV 2A(g) rarr 2A^(+) (g) DeltaH = x Find the value of x in eV.

The work function of a mental is X eV when light of energy 2X eV is made to be incident on it then the maximum kinetic energy of emitted photo electron will be

The statement: If x^(2) is not even, then x is not eve is converse of the statement…………

M_((g)) to M_((g))^(+) + e^(-) , DeltaH =100 eV , M_((g)) to M_((g))^(2+) + 2e^(-) , DeltaH =250 eV Which is incorrect statement ?
