Ephoton = Ebind + Ekin
hc/delta = Ebind + 0.5mv^2/
I subbed in values provided and rearranged to find velocity.. It
gave me a negative value.
(Ebind = 206000 J, h= 6.6261x10^-34, c= 2.99x10^8, delta = 215 x

Hi,
can anyone please help me with this? i have no clue how to define
if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
