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:
of
is 0.0513
Explanation:
Solubility equilibrium of :
Solubility product of (
) is written as-
Where and
represents equilibrium concentration (in molarity) of
and
respectively.
Molar mass of = 183.48 g/mol
So, solubility of =
= 0.234M
1 mol of gives 1 mol of
and 2 moles of
upon dissociation.
so, = 0.234 M and
=
so,
