Answer: The range of wavelengths of light that can be used to cause given phenomenon is 
.
Explanation:
Given: 222 kJ/mol (1 kJ = 1000 J) = 222000 J
Formula used is as follows.
where,
E = energy
h = Planck's constant = 
c = speed of light = 
Substitute the values into above formula as follows.
Thus, we can conclude that the range of wavelengths of light that can be used to cause given phenomenon is .
Answer:
it is necessary to keep our sense organ clean and healthy for if don't clean our sense organ clean we may suffer from many disease like if we don't clean eyes we can't see anything, if we don't clean ear we can't listen anything, and if we don't clean nose it hard for breathing, and if we don't cleanour tounge should be dry and become our breathe smell is very bad, and if we don't clean skin we may suffer from many disease and that may we get cancer also.

Answer:
c
Explanation:
because the ion are Mobil which mean they are free not combined and carry a charge but when they are combined/ fixed in position they can't carry a charge so therefore can't conduct electricity :)
