Answer:
6.92; neutral
Explanation:
Kw = [H^+][OH^-] = 1.47 × 10^-14
pKw = pH + pOH = 13.83
At neutrality, [H^+] = [OH^-] and pH = pOH
2pH = 13.83
pH = 6.92
The pH will be 6.92.
At 303 K, this will be the neutral pH, because [H^+] = [OH^-]
The wavelength of the radiation is 4.7 x 10⁻⁹ m
What is the Einstein's Formula for Energy?
The energy
E is given, from Einstein's formula, as:
E=h⋅ν
Where:
h=6.63×10⁻³⁴Js is Planck's constant;
ν is the frequency.
You can relate frequency and wavelength
λ through the speed of light c as:
c=λ⋅ν
So finally you get:
E=hc/λ
It is given in the question
The energy of a photon is 4.23 x 10⁻¹⁷ J.
Wavelength = ?
λ = hc/E
λ = 6.63×10⁻³⁴x 3 x 10⁸ / 4.23 x 10⁻¹⁷
λ = 4.7 x 10⁻⁹ m
Therefore the wavelength of the radiation is 4.7 x 10⁻⁹ m .
