NacI because like it do . hope it helps
Explanation:
Obviously there's an exothermic reaction going on, which suggests a neutralisation reaction. A dark blue precipitate is formed, which could be a copper salt. So a new substance formed.
The formula is simple.
Kinetic energy = Photon energy - Binding energy
In some places, binding energy is also called work function.
So, Photon energy =
=
(Here we multiply lambda by 10^(-9) to change nm to m)
=
J
Change it to ev from Joule (J)
so, Photon energy =
J =
= 7.8 eV
Now, KE = 7.8 - 3.31 = 4.57 eV
Done !!!
