Answer:
the frequency of photons 
Explanation:
Given: first ionization energy of 1000 kJ/mol.
No. of moles of sulfur = 1 mole

We know that plank's constant

Let the frequency of photons be ν
Also we know that ΔE = hν
this implies ν = ΔE/h


Hence, the frequency of photons 
Seas are smaller than oceans. Oceans are where land and water meet, and are usually bigger.
0.0015 kilometers is for sure the answer!
I would say physical, because a physical change is affecting the form of a chemical substance, but not it's chemical makeup.
