Answer:
We have the final answer as

Explanation:
To find the energy of a photon of this light we use the formula
<h3>E = hf</h3>
where
E is the energy
f is the frequency
h is the Planck's constant which is
6.626 × 10-³⁴ Js
From the question
f = 7.08×10¹⁴ Hz
We have
E = 7.08×10¹⁴ × 6.626 × 10-³⁴
We have the final answer as

Answer:
See explanation
Explanation:
The electrolysis of nickel(II) iodide yields nickel solid and iodine gas.
In the oxidation half equation;
2I^-(aq)-------> I2(g) + 2e
In the reduction half equation;
Ni^2+(aq) + 2e -----> Ni(s)
These are the half equations of the process;
The overall equation is;
Ni^2+(aq) + 2I^-(aq)-------> NiI2
It is not good conductors of electricity or heat!
